Irrlicht Engine Changelog

What's new in Irrlicht Engine 1.8.1

Nov 28, 2013

For speed improvement the following attributes accessible by ISceneManager::getParameters() are no longer updated in release:
"culled", "calls", "drawn_solid", "drawn_transparent", "drawn_transparent_effect".
They can be enabled by compiling Irrlicht with the define _IRR_SCENEMANAGER_DEBUG.
Thanks @hendu for reporting, see http://irrlicht.sourceforge.net/forum/viewtopic.php?f=2&t=48211 for the discussion.
Fix compile problem with CIrrDeviceSDL on VS2008 (and maybe other systems). Thanks @HellFlip for reporting.

Fix buffer overrun in x-loader
Fix cursor visibility update problem under Windows 8
Fix irredit links in loadScene/saveScene docs.
Fix issue in CAnimatedMeshSceneNode::clone which caused a crash.

New in Irrlicht Engine 1.8 (Nov 28, 2013)

Let sphere mesh use full opaque color, just as all the other ones do
Gcc on Win32 (MinGW) now also works with the _w file access functions when compiled with _IRR_WCHAR_FILESYSTEM.
Fix a bunch of off-by one errors in irr::core::string in functions equals_substring_ignore_case, findFirst, findFirstChar, findNext, findLast, findLastChar, replace, remove and removeChars.
This prevents some potential memory access errors, find functions no longer try to find the \0, replace no longer replaces the \0 and remove no longer tries to remove it (which did remove the last character instead).
matrix4::setRotationAxisRadians added
user clipplanes fixed
Skip rendering of lines, points, and polygons, as these lead to crahses due to wrong access to the vertex lists. A fix would need major rewrite of the vertex cache, or at least some other render methods.
Add mipmap generation for makeColorKeyTexture
Add another saveScene overload which allows to pass in a user-created XMLWriter. Patch suggested by eversilver.
quaternion conversions to and from matrix4 no longer invert rotations.
To test if your code was affected by this you can set IRR_TEST_BROKEN_QUATERNION_USE in quaternion.h and try to compile your application.
Then on all compile-errors when you pass the matrix to the quaternion you can replace the matrix transposed matrix.
For all errors you get on getMatrix() you can use quaternion::getMatrix_transposed instead.
CGUIEnvironment::loadGui - loading a gui into a target-element no longer messes up when the gui-file contained guienvironment serialization.
Colladawriter now exports materials per node when those are used in Irrlicht
Colladawriter now writing matrices for node transformations as old solution did not work with CDummyTransformationSceneNode's.
Colladawriter no longer create an extra node for the scenemanger as has that job in Collada.
Colladwriter no longer makes all Scenenodes children of ambient-light as that can be parallel on the same layer instead.
Colladareader now creates the ambient-light correct instead of creating a point-light for it.
Add new parameter to array reallocate function. This prevents a reallocation in case the array would become smaller. As the reallocation operation is quite time consuming, this can be avoided on request now, on the expense of more memory consumption.
Add IAnimatedMeshSceneNode::getLoopMode
CSceneNodeAnimatorCameraFPS now resets the key-input when it was disabled (thx @ gerdb for reporting and patch-proposal)
Properly destroy OpenGL resources on linux
Fix diplay bux in the attribute-panel of the GUIEditor. Fixes bug 3517314 (thx @Darkcoder for reporting).
Allow caching cursor position on X11 to work around slow XQueryPointer calls
Make sure after EGET_EDITBOX_ENTER and EGET_COMBO_BOX_CHANGED event processing no more code is executed for the corresponding editbox or combobox objects to allow clearing the environment on those actions
Fix string::replace which failed replacing substrings at the end when the replacement was longer
Struct packing works now with gcc 4.7 changes on MinGW
Struct packing uses now same solution throughout (by including headers in corresponding places)
User can now set characters used for decimal point in fast_atof for localisation.
Add parameter useAlphaChannel to second IGUIEnvironment::addImage function.
Get rid of unnecessary warning "Could not load sprite bank because the file does not exist" for "#defaultfont".
Fix MRT disabling. Bug found and fixed by hendu.
core:::array::reallocate returning now immediately when it has nothing to do. Should reduce a lot of memory thrashing on irrArrays.
Start mesh animations at first OnAnimate , before start-frame was rather random. Thx @Auria for reporting and patch proposal.
renderTargetTexture now working with ECF_R5G6B5
add -fPic in c::b linux fast math shared build.
Fix by Auria for starting the animated meshes only at first OnAnimate instead of at random times and animation frames.
Add support for MAX_COMBINED_TEXTURES, which allows more texture support than with the original fixed pipeline texture check under OpenGL. Now, more than 4 textures should also work with newer gfx cards and drivers, which often only support 4 fixed pipeline textures.
triangle3d::isPointInsideFast now using some epsilon to catch all points on the borders.
triangle3d::getIntersectionOfPlaneWithLine calculates now with higher precision for more exact results.
triangle3d::isOnSameSide (used by isPointInside) calculates now with higher precision and uses some epsilon to make it work with larger integers and less floating point troubles. Slightly slower now.
new function equalsByUlp to test for spacing between floating point numbers.
speedup for collada writing.
speedup for xml-writing.
Fix 8bit grey image TGAs, which were not working due to missing palette. Also switched to RGB8 format, as otherwise a loss in precision would occur. Thanks to Klunk for the error report and a test image.
fixed issues with a D3D driver and Aero effects.
Fix font-drawing in CGUIButton to use EGDF_BUTTON again (thx @DJLinux for reporting).
Add texture cache with proper reference handling. This avoids deletion of textures while still being active on the GPU. Test case and fix by m(att)giuca
CFileSystem::removeFileArchive now checking for normalized path
Fix zip's with passwords on 64-bit systems (thx @ Dr. Gladman for writing the bugfix)
replace asserts in tests with macro assert_log to allow running all tests through on problems.
added IGUIElement::setName and IGUIElement::getName (similar to ISceneNode)
irr::s64 support
line2d::getClosestPoint can now also get the closest point on the line additional to only checking for closest point on the line-segment.
avoid division by zero in line2d::getClosestPoint when start- and endpoint are identical
Support for sw drivers under OSX
Fix font-loading which got broken by fixed xml-loading. Thanks @ pc0de for finding and providing a test and patch.
Don't crash draw2DSpriteBatch when it get's no textures.
Add support for int passing in setShaderConstant
Support for better collada texture wrapping support on loading.
Fix for render context change where only the window id is given. We now try to change only the window ID, keeping context and display unchanged. Suggestion by vovo4ka from the forum.
XML-reader now ignores all whitespace-only EXN_TEXT elements as old way didn't work in cross-platform way (and arguably also not well on Windows).
CXMLReader initializes IsEmptyElement now.
line2d::intersectWith and and line2d::getClosestPoint work now also with integers.
line2d::getMiddle and line3d::getMiddle work now also with integers. But can be slower for compilers which are not optimizing division by 2 to multiplication by 0.5 for floats.
Add Nadro's initial Cg support. Example 10 is enhanced to allow also Cg shaders.
Add mipmap support from FBO extension, patch by Nadro.
Add vertex optimization algorithm submitted by curaga
rename texureBlend functions to textureBlend
Add threshold for slerp calculation, switching between linear and slerp at this point.

Reduction of multiple skinning the same mesh and frame in one render cycle
Added ISceneNodeAnimatorCameraFPS::getKeyMap and a new ISceneNodeAnimatorCameraFPS::setKeyMap.
CSceneNodeAnimatorCameraFPS uses now SKeyMap instead of SCamKeyMap (structs were identical which was confusing and there wasn't any explanation in comments, so I decided to simplify it).
Add some workaround to MeshViewer to show how we can currently fix the FPS-cam when users to alt-tab while moving. We can improve that some day when we have focus-events, but this works for now.
Fix LZMA decompression
Ply normal fixes

CGUISkin::draw3DSunkenPane no longer ignores fillBackGround in non-flat mode. Also borderlines are no longer drawn overlapping to avoid ugly corners.
CDummyTransformationSceneNode::clone() added.
IParticleSystemSceneNode::doParticleSystem now public to allow rendering outside scenegraph.
getRelativeFilenames updates and fixes
Renamed IOSOperator::getOperationSystemVersion to getOperatingSystemVersion. Changed return type from wchar_t to core::stringc, as that's the internal representation the name is built on.

Added suppport for right-to-left (RTL) text, supplied by Auria from STK
Added ISceneManager::createSceneNodeAnimator to create animators by name
The Makefile now creates a symlink from the soname to the binary name during install. Binary compatibility is only confirmed between same minor releases.
Added SMF mesh loader, loads meshes from 3D World Studio. Originally written by Joseph Ellis
The loader selection process now consistently checks loader lists in reverse order, so new loaders added to Irrlicht override the internal ones. This applies when adding external mesh, image, scene and archive loaders, image writers, plus node, animator and GUI element factories.
Added getters to retrieve mesh, scene and archive loaders.
Added ISceneLoader interface and .irr loader. Users can now add their own scene loaders to the scene manager and use them by calling loadScene.
Renamed IGUIElement::bringToBack to sendToBack, like in Windows
Send EGET_ELEMENT_CLOSED event when context menus should be closed (thx @ Mloren for reporting).
Added treeview to GUI editor, provided by Armen

Fixed panel scrollbars in GUI editor, reported by Armen
Fix b3d loading of files with mixed mesh/bone sections.
Fix particle emitters which used integer random numbers so far. The distributions of the particles should be much better (and the code also somewhat faster) now.
Add new random method frand: Returns a random number in the interval [0..1] and gives better distributions than using fmodf on the integer number.
Add node parameter to saveScene and loadScene. saveScene saves the given node and all descendants to the file (if 0, the full scene is saved as before). loadScene loads all elements of the scene as childs of the given node. As before, 0 would load the file on the top level (scenemanager).
Add method to make a filename relative to a given directory.
Fix setMesh to correctly update the joints cache.
Fix setting transition time of skinned meshes back to 0.
Add some getters to IGUIImage: getImage, getColor
Fix OpenGL FBODepthTexture to create less overhead
Fix MRT disabling under OpenGL
API change: Added write only lock mode for textures. The lock method has changed the signature and uses an enum parameter now instead of a bool. The default is still to lock for read/write (previously 'false'). The old 'true' value should be replaced by ETLM_READ_ONLY.
Speedup deleting of particles
Add function IParticleSystemSceneNode::clearParticles
Fix RTT render states under OpenGL
Fix AntiAliasing setup under Windows/OpenGL in case no AA is available
Fix transformation matrices when RTT used
API change: getScreenCoordinatesFrom3DPosition has a new parameter, which needs to be set to true to get the original behavior. Now, the method returns coordinates which would fit as render coordinates of a currently enabled viewport. With the parameter set to true the result would fit only after the viewport is reset to full window rendering.
More checks for Stencilbuffer
Improve render state resets
Fix MRT handling
Fix file search
Add flag and method to disable clipping of the text to the gui element rectangle in GUI static text.
addShadowVolumeSceneNode now replaces an existing shadow. One should avoid to call this method multiple times without changing any parameter, as it is quite time consuming and cannot recognize the duplicate calls.
Add function IGUIEnvironment::removeFont (TODO: Does not remove the texture from cache so far)
Fixed mem leak in mountfilesystem
Update to libjpeg 8b, zlib 1.2.5, bzip2 1.0.6, libpng 1.4.4 and lzma from 9.20 SDK

Fix blend states for MRTs
64bit targets for MSVC added
The following functions will now use a "ISceneNode *" instead of a "const ISceneNode *":
ITriangleSelector::getSceneNodeForTriangle, ISceneNodeAnimatorCollisionResponse::getCollisionNode, ISceneCollisionManager::getCollisionPoint and ISceneCollisionManager::getCollisionResultPosition.
As collision functions often are followed by changing node positions users where so far forced to using const_casts (found by Greenya).
Add vector3d::getAs3Values (patch provided by slavik262)
Add function to SViewFrustum to get corners of the near plane (patch provided by Matt Kline, aka slavik262)
ParticleFadeOutAffector::setFadeOutTime can no longer be set to invalid values
ParticleFadeOutAffector uses now throughout u32 for fadeOutTime (found by greenya)
Add missing access function CParticleSystemSceneNode::getAffectors() (seen by B@z)
Add missing setters/getters for particle emitters (seen by B@z)
Compile-defines can now be disabled from Makefiles/Projectfiles instead of having to change IrrCompileConfig.h each time.
IGUITabControl::setActiveTab should only take IGUITab* and not IGUIElement* (thx to greenya for finding)
Add new skin-colors: EGDC_GRAY_WINDOW_SYMBOL, EGDC_EDITABLE, EGDC_GRAY_EDITABLE, EGDC_FOCUSED_EDITABLE
Disabled state is now extended to sub-elements
Make disabled state for several elements more visible
Bugfix: Icons in tabcontrol get now affected immediately by skin-changes

XML reader bugfix
Disable mipmaps in 2d mode everywhere
Add xml example written by Yoran Bosman.
Fix cursor cleanup under Linux when using multiple devices
Fix collada parser
Fix MRT reset under D3D
Add a generic attribute interface for querying video driver attributes which are not necessarily of type bool. This interface allows to check certain supported features, such as the number of user clip planes, supported lights and textures, MRTs, and other things. The interface might change in the future, but it's fully functional already. The supported attributes are listed in the API docs of the function:
The following names can be queried for the given types:
MaxTextures (int) The maximum number of simultaneous textures supported by the driver. This can be less than the supported number of textures of the driver. Use _IRR_MATERIAL_MAX_TEXTURES_ to adapt the number.
MaxSupportedTextures (int) The maximum number of simultaneous textures supported by the fixed function pipeline of the (hw) driver. The actual supported number of textures supported by the engine can be lower.
MaxLights (int) Number of hardware lights supported in the fixed function pipieline of the driver, typically 6-8. Use light manager or deferred shading for more.
MaxAnisotropy (int) Number of anisotropy levels supported for filtering. At least 1, max is typically at 16 or 32.
MaxUserClipPlanes (int) Number of additional clip planes, which can be set by the user via dedicated driver methods.
MaxAuxBuffers (int) Special render buffers, which are currently not really usable inside Irrlicht. Only supported by OpenGL
MaxMultipleRenderTargets (int) Number of render targets which can be bound simultaneously. Rendering to MRTs is done via shaders.
MaxIndices (int) Number of indices which can be used in one render call (i.e. one mesh buffer).
MaxTextureSize (int) Dimension that a texture may have, both in width and height.
MaxGeometryVerticesOut (int) Number of vertices the geometry shader can output in one pass. Only OpenGL so far.
MaxTextureLODBias (float) Maximum value for LOD bias. Is usually at around 16, but can be lower on some systems.
Version (int) Version of the driver. Should be Major*100+Minor
ShaderLanguageVersion (int) Version of the high level shader language. Should be Major*100+Minor.
Fix getRotationDegrees
Add creation parameter which allows to disable highres timers on Windows upon device creation.
Several transparency setup bugs fixed. Now, alpha_vertex_blend uses proper alpha blending instead of a mixed add/alpha blending.
Added a method to get real time and date in a human readable struct
Fix add folder archives method to support files without trailing slashes.
fix transparent_reflection_2_layers
Add support for MSVC 2010
Fix "unsupported format" warning on RTT usage
Add IGUIElement::bringToBack (patch written by DtD, although I'm to blame for the function-name)
BurningVideo:
add Normalmap Rendering (one light only), pushed Burningvideo to 0.46
add Stencil Shadow Rendering (one color only and 32 bit only),
pushed Burningvideo to 0.47
internal vertexformat changed
changed fixpoint from 9 to 10 bit fract resolution
renamed createBurningVideoDriver to createBurningVideoDriver and uses SIrrlichtCreationParameters like opengl
internal interfaces for the trianglerenders unified.
Example 11, changed the light billboards to use the light color.
allow to disable the bump/parallax on the earth like in the room ( with transparency )
added DDS Image files, DXT2, DXT3, DXT4, DXT5, based on code from nvidia and Randy Reddig
added Halflife 1 Model Loader (based on code by Fabio Concas)
Halflife 1.1.0.8, Counter-Strike 1.6 working
Load all Textures ( can even optimize it to texture atlas ), all bone animation, all submodels.
But to make use of the values (named animation, mouth animation)
the Interface for IAnimatedMeshSceneNode has to be redone.

Fix incorrect cursorpos for resizable windows on Windows Vista (found and patched by buffer)
Change the beginScene window parameter from void* to SExposedVideoData&. This will allow to manage contexts for OpenGL at some point.
Add bzip2 and LZMA decompression modes for zip loader.
Add OBJ_TEXTURE_PATH and B3D_TEXTURE_PATH to SceneParameters to allow setting texture-paths for obj and b3d.
Irrlicht keeps now filenames additionally to the internally used names, thereby fixing some problems with uppercase-filenames on Linux.
Bugfix: Mousewheel no longer sends EMIE_MOUSE_WHEEL messages twice on Linux.
Use latest jpeglib
refactoring: E_ATTRIBUTE_TYPE and IAttribute have now own headers
CStringWArrayAttribute speedup
SceneNodeAnimatorFollowSpline can now loop and pingpong
Meshviewer.example got some fast-scale buttons.
Support AES-encrypted zip files. Should work with 128, 196, and 256 bit AES. This addition also adds a new PRNG, SHA, and other algorithms to the engine, though no interface is yet added for them. The implementation of the encryption algorithms is provided by Dr Brian Gladman.
flattenFilename and getAbsolutePath fixed and properly added at several places.
Added geometry shaders for OpenGL. A first version of the code was submitted by Matthew Kielan (devsh).
Bugfix: irrArray should no longer crash when using other allocators.
Add MaterialViewer example.
Texture activation now back in setMaterial, which simplifies writing external material renderers (OpenGL only).

Changed colors for window-title caption to keep them readable when not active.
Draw sub-menus to left side if they would be outside main-window otherwise.
Give ListBox better defaults for the ScrollBar stepsizes.
Double and triple click events now for each mouse-button. Old events for that got removed.
Fix adding archives twice, which caused multiple archives of the same name and type covering each other. This one required a texture name change from using backslashes to slashes under Windows.
Give access to texture mipmaps. You can provide custom mipmap textures upon generation, regeneration, and locking.
Make sure the provided data is large enough and covers all miplevels. Also the returned pointer (from lock) will only cover the smaller data of the mipmap level dimension chosen (level 0 is the original texture).
Separate TextureWrap mode into U and V fields
Add mirror texture wrap modes
windows show now active/inactive state

Fix pingpong for CSceneNodeAnimatorFlyStraight (found by gbox)
Fix bug with IGUIEditBox where the cursor position is reset on text change.
Make sure the window top-left corner on Windows is not negative on start so that Windows sytem-menu is always visible.
Fix problem that the window did sometimes not get the keyboard focus in X11 in fullscreen. Add more debug output in case focus grabbing goes wrong.
Fix screensize in videodriver when we didn't get the requested window size. This also prevents that gui-clicks are no longer synchronized with gui-drawing and elements can't be hit anymore.
Bugfix: Prevent a crash when getTypeName was called for the guienvironment. EGUIET_ELEMENT got changed for this.
Bugfix: Horizontal centered font with linebreaks draw now all lines. For example multiline TextSceneNodes work again.
Bugfix: spinbox can no longer get in an endless loop due to floating point rounding error (found by slavik262)
API change!! Disabled AntiAliasing of Lines in material default
Please enable this manually per material when sure that it won't lead to SW rendering.
IGUIComboBox: clicking on the statictext displaying the active selection does now close and open listbox correctly. (Bug found by Reiko)
Scrollbuttons in IGUITabControl adapt now to tab-height.
Fix texturing of cylinder mesh
Fix modal dialog position (found by LoneBoco: http://sourceforge.net/tracker/?func=detail&aid=2900266&group_id=74339&atid=540676)
Fix DMF loading
Fixing left+right special keys (ctrl, shift, alt) on Win32 (thanks to pc0de for good patch-ideas).

Bugfix: CGUIToolBar::addButton does no longer mess up when no image is set and does now actually work with the text.
Fix ninja animation range which got messed up a little when b3d animations got fixed (thx gbox for finding)

New in Irrlicht Engine 1.6 (Mar 19, 2012)

Added IFileSystem::createEmptyFileList, exposed IFileList::sort, addItem and added getID
Fix MAKE_IRR_ID so it can be used from outside the irr namespace (Micha's patch)
Renamed some methods in ISkinnedMesh to match the official Irrlicht naming scheme according to createXXX()
Change debug data to draw using lines instead of arrows, which is much faster. Patch by pc0de
Fix a bug with FPS camera animator causing stutters. Patch by FuzzYspo0N
Fix scrolling controls in CGUITabControl
Fix a bug when getting optimal texture size in D3D drivers, by Jetro Lauha (tonic)
Added EGDS_TITLEBARTEXT_DISTANCE_X and EGDS_TITLEBARTEXT_DISTANCE_Y to GUI, submitted by FuzzYspo0N
Fix for UFT8 filenames displayed in file dialog, patch by MadHyde.
Added const method for array::binary_search, potentially slow as it doesn't sort the list!
Add support for scaling button images.
Irrlicht can now come with multiple device types compiled in, the device to use is selected by SIrrlichtCreationParameters.DeviceType. This defaults to EIDT_BEST which automatically select the best device available starting with native, then X11, SDL and finally the console.
Added support for EXP2 fog distribution. This required a change in the setFog parameters where now an enum value instead of the bool linear is given.
IFileSystem changes:
Renamed the following functions-
IFileArchive::getArchiveType to getType
IFileSystem::registerFileArchive to addFileArchive
IFileSystem::unregisterFileArchive to removeFileArchive
IFileArchive::openFile to createAndOpenFile
New enum, E_FILE_ARCHIVE_TYPE. getType on IArchiveLoader and IFileArchive now both return this.
IFileSystem::addFileArchive takes a parameter to specify the archive type rather always using the file extension. IFileSystem::addZipFileArchive, addFolderFileArchive and addPakFileArchive now use this but these functions are now marked as deprecated. Users should now use addFileArchive instead.
Added TAR archive loader.
The ZIP archive loader can now load gzip files, combined with the TAR loader this means Irrlicht now has native support for .tar.gz
Currently this must be done in two calls, for example:
fileSystem->addFileArchive("path/to/myArchive.tar.gz");
fileSystem->addFileArchive("myArchive.tar");
Fix highlighting in IGUIEditBox where kerning pairs are used in the font. For example in future italic, OS or other custom fonts.
IOSOperator::getTextFromClipboard returns now const c8* instead of c8*
Support for copy&paste on linux (X11) added (fixing bug 2804014 found by Pan)
bugfix for 2795321 found by egrath: Don't rely anymore on broken XkbSetDetectableAutoRepeat.
bugfix: CMountPointReader::openFile no longer returns true for empty files. Corresponding test added.
Direct3D now also uses screen coordinates in 2d mode, just like OpenGL. This means that screen coords are going from 0..ScreenWidth and 0..ScreenHeight instead of -1..1.
ALT+F4 keypress now closes Windows SDL device
Allow Direct3D drivers in SDL, patch by Halifax
Added compiler error when attempting to compile with VC6.
Use setWindowTextA in Windows device for WIN64 platform, posted by veegun
ELL_ERROR log events are now created when shaders fail to compile or link, reported by Halan
irrList now uses irrAllocator, fixed by Nox
Added IGUIWindow::setDraggable and IGUIWindow::isDraggable, by Nox
Added SGI RGB file reader by Gary Conway, for loading Silicon Graphics .rgb, .rgba, .sgi, .int and .inta textures
Renamed setResizeAble to setResizable
Added new device method minimizeWindow which minimizes the window (just as if the minimize button has been clicked).
SkyDome is now serialized correctly
Added PLY mesh reader and writer
Ensure ListBox on combo box doesn't hang off the bottom of the GUI root, by Matthias Specht
Made IGUIElements recalculate clipping rectangle after setNotClipped, reported by Aelis440
Bug fix for the combo box where it showed white text instead of skin colour before being focused, fix posted by drewbacca
EGDS_MESSAGE_BOX_HEIGHT is now honoured, bug reported by Spkka
Fixed a bug in the edit box where events are sometimes sent to a null parent, reported by Sudi.
Coordinate system fix for OpenGL in SDL device
Added generic console device. You can now use Irrlicht to create and manipuate graphics on a shell where no graphics hardware
or windowing system is available. To enable it uncomment #define _IRR_USE_CONSOLE_DEVICE_ in IrrCompileConfig.h
The console device can now present images from the software drivers and display them as ASCII art in the console
By default it replaces the default font in the skin, to prevent fonts from being huge.
Fixed problems with changing cursor visibility while mouse is pressed on windows
Allow control of background drawing in listbox
Allow control of drawing background and titlebar in windows
Improved window serialization
Add mouse events EMIE_MOUSE_DOUBLE_CLICK and EMIE_MOUSE_TRIPLE_CLICK (thx to Ulf for patch proposal)
Set "ButtonStates" for mouse events also on Linux (was only for Windows formerly)
Add Shift+Control states to mouse event
bugfix (2003238): serialize modal screens
allow stacking modal screens
allowing hiding modals
replace many IsVisible checks with virtual isVisible() checks in IGUIElement
bugfix: reset selected row when clearing CGUITable
adding events EGET_EDITBOX_CHANGED and EGET_EDITBOX_MARKING_CHANGED
prevent editbox from recalculating its textbreaking each frame
let spinbox react on each textchange without waiting for enter to prevent getting value changes without corresponding EGET_SPINBOX_CHANGED events.
new test for zipreader
prevent dropping objects accidentally in many set functions
Reversed change in vector3d::normalize.
Works now again as documented and a corresponding test has been added.
Does fix bug 2770709 (https://sourceforge.net/tracker/?func=detail&aid=2770709&group_id=74339&atid=540676)
Animations can now be paused by setting the fps to 0.
Avoid fp-precision problem in getPickedNodeBB (see also http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=33838&highlight=).
This change might also fix the problem with picking nodes found by aanderse (http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=32890&highlight=)
implemented isALoadableFileFormat ( File *file ) for the Archive Loader
PixelBlend16 and PixelBlend16_simd are working for the new rules.
bugfix. CLightSceneNode didn't correctly update it's attributes
vector template and equals tests
also set the equal test for s32 to behave like the f32 routine.
The function equals always implements a weak test.
that means a tolerance MUST always be used if you use the equal function. default is 1.
VideoDriver drawPixel
The HW renderes are using the alpha components for blending.
The Software Renderes and image loaders are using CImage::setPixel copy.
so setPixel is engaged to either blends or copy the pixel
default: false
Burningvideo
added RenderMaterial EMT_SPHERE_MAP
pushed burningsvideo to 0.43
added RenderMaterial EMT_REFLECTION_2_LAYER
pushed burningsvideo to 0.44
set EMT_TRANSPARENT_ALPHA_CHANNEL_REF
to use AlphaRef 0.5 like Direct3D
One Note: in OpenGL there is know difference between sphere_map and reflection layer
both using GL_TEXTURE_GEN_MODE GL_SPHERE_MAP, whereas in d3d one time using camera_normal
on sphere and reflection on refletcion_layer.
The visual difference is that on sphere map the "image is not moving" when you rotate the
viewer. For Burning i took the opengl visual. always moving
rename quake3 SEntity to IEntity to be confom with IShader
fixed createMeshWith2TCoords, normals were missing during copy.
added
//! Creates a copy of the mesh, which will only consist of S3DVertex vertices.
IMesh* CMeshManipulator::createMeshWith1TCoords(IMesh* mesh) const
added io::IFileSystem* CSceneManager::getFileSystem()
added virtual const c8* ISceneManager::getAnimatorTypeName(ESCENE_NODE_ANIMATOR_TYPE type);
added CSceneNodeAnimatorFlyCircle::radiusEllipsoid.
if radiusEllipsoid == 0 the default circle animation is done
else radiusEllipsoid forms the b-axe of the ellipsoid.
> gummiball bouncing
added ISceneManager::createFlyStraightAnimator variable bool ping-pong
used in loop mode to device if start from beginning ( default ) or make ping-pong
> straight bouncing
changed IFileSystem::registerFileArchive
remove the index of the hierarchy and added a new interface method
//! move the hirarchy of the filesystem. moves sourceIndex relative up or down
virtual bool moveFileArchive( u32 sourceIndex, s32 relative ) = 0;
bugfix and changes in SViewFrustum::SViewFrustum
wrong size of Matrices copy.
renamed E_TRANSFORMATION_STATE_2 to E_TRANSFORMATION_STATE_FRUSTUM
therefore also changed SViewFrustum::setTransformState to not tap
in the pitfall again of wrong memory...
moved
//! EMT_ONETEXTURE_BLEND: has BlendFactor Alphablending
inline bool textureBlendFunc_hasAlpha ( E_BLEND_FACTOR factor ) const
from the material renderes ( 3x declared ) to SMaterial.h
updated managed light example to use standard driver selection
BurningsVideo
LightModel reworked.
Point Light & Direction Light works for Diffuse Color as expected
Specular and Fog still have problems ( needs new pixel shader )
pushed burningsvideo to 0.42 for this major step
removed obsolete matrix transformations
renamed E_TRANSFORMATION_STATE_2 to E_TRANSFORMATION_STATE_BURNING
cleaned line3d.h vector3d.h template behavior.
many mixed f32/f64 implementations are here. i'm not sure if this should be
the default behavior to use f64 for example for 1.0/x value, because they
benefit from more precisions, but in my point of view the user is responsible
of choosing a vector3d or vector3d.
added core::squareroot to irrmath.h
> for having candidates for faster math in the same file
added AllowZWriteOnTransparent from SceneManager to burningsvideo
added hasAlpha() to ITexture
This info can be used for e.q to downgrade a transparent alpha channel blit
to add if the texture has no alpha channel.
FileSystem 2.0 SUPER MASTER MAJOR API CHANGE !!!
The FileSystem is now build internally like for e.g. the image- and meshloaders.
There exists a known list of ArchiveLoaders, which know how to produce a Archive.
The Loaders and the Archives can be attached/detached on runtime.
The FileNames are now stored as core::string. where c16 is toggled between char/wchar
with the #define flag _IRR_WCHAR_FILESYSTEM, to supported unicode backends (default:off)
Replaced most (const c8* filename) to string references.
Basically the FileSystem is divided into two regions. Native and Virtual.
Native means using the backend OS.
Virtual means only use currently attached IArchives.
Browsing
each FileSystem has it's own workdirectory and it's own methods to
create a FileTree
add/remove files & directory ( to be done )
Hint: store a savegame in a zip archive...
basic browsing for all archives is implemented.
Example 21. Quake3Explorer shows this
TODO:
a file filter should be implemented.
The IArchive should have a function to create a filetree
for now CFileList is used.
Class Hierarchy:
IArchiveLoader: is able to produce a IFileArchive
ZipLoader
PakLoader
MountPointReader ( formaly known as CUnzipReader )
IFileArchive:
ZipArchive
PakArchive
MountPoint (known as FolderFile)
IFileSystem
addArchiveLoader
changed implementation of isALoadableFileExtension in all loaders
to have consistent behavior
added a parameter to IFileList * createFileList
setFileListSystem
allows to query files in any of the game archives
standard behavior listtype = SYSTEM ( default)
CLimitReadFile
added multiple file random-access support.
solved problems with mixed compressed & uncompressed files in a zip
IrrlichtDevice
added:
virtual bool setGammaRamp( f32 red, f32 green, f32 blue, f32 brightness, f32 contrast ) = 0;
virtual bool getGammaRamp( f32 &red, f32 &green, f32 &blue ) = 0;
and calculating methods to DeviceStub.
implemented in Win32, SDL, Linux TODO: other Devices
irrlicht.h
changed exported irrlicht.dll routines createDevice, createDeviceEx, IdentityMatrix
to extern "C" name mangling.
ParticleSystem
removed the private (old?,wrong?) interface from the ParticleEffectors
to match the parent class irr::io::IAttributeExchangingObject::deserializeAttributes
Generic
vector3d& normalize() optimized
added reciprocal_squareroot for f64
dimension2d
added operator dimension2d& operator=(const dimension2d& other)
to cast between different types
vector2d bugfix operator+=
C3DSMeshLoader renamed chunks const u16 to a enum
removing "variable declared but never used warning"
added a global const identity Material
changed all references *((video::SMaterial*)0) to point to IdentityMaterial
removed warning: "a NULL reference is not allowed"
modified IRRLICHT_MATH to not support reciprocal stuff
but to use faster float-to-int conversion.
core::matrix4
USE_MATRIX_TEST
i tried to optimize the identity-check ( w.r.t. performance)
i didn't succeed so well, so i made a define for the matrix isIdentity -check
for now it's sometimes faster to always calculate versus identity-check
but if there are a lot of scenenodes/ particles one can profit from the
fast_inverse matrix, when no scaling is used. further approvement could
be done on inverse for just translation! ( many static scenenodes are not rotated,
they are just placed somewhere in the world)
one thing to take in account is that sizeof(matrix) is 64 byte and
with the additional bool/u32 makes it 66 byte which is not really cache-friendly..
added buildRotateFromTo
Builds a matrix that rotates from one vector to another
irr::array. changed allocating routine in push_back
added a new method setAllocStrategy,
safe ( used + 1 ), double ( used * 2 + 1)
better default strategies will be implemented
removed binary_search_const
i added it quite a long time ago, but it doesnt make real sense
a call to a sort method should happen always. i just wanted to safe
a few cycles..
added binary_search_multi
searches for a multi-set ( more than 1 entry in the sorted array)
returns start and end-index
changed some identity matrix settings to use core::IdentityMatrix
added deletePathFromFilename to generic string functions in coreutil.h and
removed from CZipReader and CPakReader
s32 deserializeAttributes used instead of virtual void deserializeAttributes in
ParticleSystem ( wrong virtual was used)
strings & Locale
started to add locale support
added verify to string
added some helper functions
XBOX
i have access to a XBOX development machine now. I started to compile
for the XBOX. Question: Who did the previous implementation?. There
is no XBOX-Device inhere. maybe it's forbidden because of using the offical
Microsoft XDK. I will implement a native or sdl device based on opendk.
irrlicht compiles without errors on the xbox but can't be used.
Windows Mobile
reworked a little. added the mobile example to the windows solution for
cross development.
added maximal 128x128 texture size for windows mobile ( memory issues )
Collision Speed Up
The Collision Speed Up greatly improves with many small static child-nodes
added COctTreeTriangleSelector::getTriangles for 3dline from user Piraaate
modified createOctTreeTriangleSelector and createTriangleSelector
to allow node == 0, to be added to a meta selector
CSceneNodeAnimatorCollisionResponse has the same problem as CSceneNodeAnimatorFPS
on first update:
Problem. you start setting the map. (setWorld). First update cames 4000 ms later.
The Animator applies the missing force... big problem...
changed to react on first update like camera.
add Variable FirstUpdate. if set to true ( on all changes )
then position, lasttime, and falling are initialized
added #define OCTTREE_USE_HARDWARE in Octree.h
if defined octtree uses internally a derived scene::MeshBuffer which has
the possibility to use the Hardware Vertex Buffer for static vertices and
dirty indices;-)
if defined OCTTREE_USE_HARDWARE octree uses internally a derived scene::CMeshBuffer
so it's not just a replacement inside the octree. It also in the OctTreeSceneNode.
define OCTTREE_PARENTTEST is also used. It's skip testing on fully outside and takes everything on fully inside
virtual void ISceneNode::updateAbsolutePosition()
changed inline CMatrix4 CMatrix4::operator*(const CMatrix4& m2) const
changed inline bool CMatrix4::isIdentity() const
to look first on Translation, because this is the most challenging element
virtual core::matrix4 getRelativeTransformation() const
Hierarchy on Identity-Check
) ->getRelativeTransform -> 9 floating point checks to be passed as Identity
) ->isIdentity () -> 16 floating point checks to be passed as Identity
inline void CMatrix4::transformBoxEx(core::aabbox3d& box) const
added isIdentity() check
changed CSceneNodeAnimatorCollisionResponse
added CSceneNodeAnimatorCollisionResponse::setGravity
needed to set the differents Forces for the Animator. for eq. water..
added CSceneNodeAnimatorCollisionResponse::setAnimateTarget
added CSceneNodeAnimatorCollisionResponse::getAnimateTarget
changed CSceneNodeAnimatorCollisionResponse::animateNode to react on FirstUpdate
TODO: set Gravity to Physically frame independent values..
current response uses an frame depdended acceleration vector.
~9.81 m/s^2 was achieved at around 50 fps with a setting of -0.03
may effect existing application..
SceneNodes
CSkyDomeSceneNode
moved radius ( default 1000 ) to constructor
added Normals
added DebugInfo
added Material.ZBuffer, added SceneManager
CVolumeLightSceneNode:
changed default blending OneTextureBlendgl_src_color gl_src_alpha to
EMT_TRANSPARENT_ADD_COLOR ( gl_src_color gl_one )
which gives the same effect on non-transparent-materials.
Following the unspoken guide-line, lowest effect as default
changed SceneNode Skydome from f64 to f32
AnimatedMesh Debug Data:
mesh normals didn't rotate with the scenenode fixed ( matrix-multiplication order)
Camera SceneNode setPosition
Camera now finally allow to change position and target and updates all
effected animators..
Device:
added the current mousebutton state to the Mouse Event
so i need to get the current mouse state from the OS
GUI
CGUIFont:
added virtual void setInvisibleCharacters( const wchar_t *s ) = 0;
define which characters should not be drawn ( send to driver) by the font.
default: setInvisibleCharacters ( L" " );
added MultiLine rendering
should avoid to us CStaticText breaking text in future
CGUIListBox
changed Scrollbar LargeStepSize to ItemHeight
which easy enables to scroll line by line
CGUIScrollBar
bug: event lost when moving outside the window
bug: Scrollbar notifyListBox notify when the scrollbar is clicked.
changed timed event in draw to OnPostRender
added GUI Image List from Reinhard Ostermeier, modified to work
FileOpenDialog
changed the static text for the filename to an edit box.
changed the interface for addEditBox to match with addStaticText
changed the interface for addSpinBox to match with addEditBox
added MouseWheel to Spinbox
changed CGUITable CLICK_AREA from 3 to 12 to enable clicking on the visible marker
CGUISpritebank
removed some crashes with empty Sprite banks
IGUIScrollBar
added SetMin before min was always 0
changed ScrollWheel Direction on horizontal to move right on wheel up, left on wheel down
IComboBox: added ItemData
optimized IsVisible check in IGUIElement::draw
Image Loaders
added TGA file type 2 ( grayscale uncompressed )
added TGA file type (1) 8 Bit indexed color uncompressed
ColorConverter:
added convert_B8G8R8toA8R8G8B8
added convert_B8G8R8A8toA8R8G8B8
Media Files

added new irrlicht logo irrlicht3.png
OctTree
added
define OCTTREE_PARENTTEST ( default: disabled )
used to leave-out children test if the parent passed a complete frustum.
plus: leaves out children test
minus: all edges have to be checked
added MeshBuffer Hardware Hint Vertex to octtree
CQuake3ShaderSceneNode:
removed function releaseMesh
Shader doesn't copy the original mesh anymore ( saving memory )
so therefore this (for others often misleading ) function was removed
changed constructor to take a (shared) destination meshbuffer for rendering
reducing vertex-memory to a half
don't copy the original vertices anymore
added deformvertexes autosprite
added deformvertexes move
added support for RTCW and Raven BSPs ( qmap2 )
added polygonoffset (TODO: not perfect)

added rgbgen const
added alphagen
added MesBuffer Hardware Hint Vertex/Index to Quake3: static geometry, dynamic indices
added Quake3Explorer examples

renamed SMD3QuaterionTag* to SMD3QuaternionTag* ( typo )
updated quake3:blendfunc
added crouch to Quake3Explorer
(modifying the ellipsiodRadius of the camera animator )
added crouch to CSceneNodeAnimatorCameraFPS
still problems with stand up and collision
Quake3MapLoader
modified memory allocation for faster loading
Quake3LoadParam
added Parameter to the Mesh-Loader
added
The still existing missing caulking of curved surfaces.
using round in the coordinates doesn't solve the problem.
but for the demo bsp mesh it solves the problem... (luck)
so for now it's switchable.
TJUNCTION_SOLVER_ROUND
default:off
BurningVideo
pushed BurningsVideo to 0.40
added blendfunc gl_one_minus_dst_alpha gl_one

Burning checks this flag and when set, it bypasses the power2 size check,
which is necessary on 3D but can be avoided on 2D.
used on fonts automatically.
added Support for Destination Alpha
Direct3D8
added 32 Bit Index Buffer
compile for XBOX
Direct3D9
fixed crash on RTT Textures DepthBuffer freed twice.
added deleteAllTextures to destructor
NullDriver
removeallTextures. added setMaterial ( SMaterial() ) to clean pointers for freed textures
ISceneCollisionManager::getSceneNodeAndCollisionPointFromRay() allows selection by BB and triangle on a heirarchy of scene nodes.
Triangle selectors created from animated mesh scene nodes will update themselves as required to stay in sync with the node.
IVideoDriver has methods to enumerate the available image loaders and writers.
Octtree scene nodes are now IMeshSceneNodes rather than ISceneNodes, and so you can call getMesh() on them.
New scene parameter B3D_LOADER_IGNORE_MIPMAP_FLAG to ignore the often missing mipmap flag in b3d files. If this parameter is true, the old pre Irrlicht-1.5 behavior is restored.
Added Mipmap LOD Bias attribute to MaterialLayer.
Added ColorMask support to selectively disable color planes on rendering.
Added support for all available depth test functions.
Add an outNode to getCollisionPoint() that returns the scene node that was hit, as well as the triangle.
Initial support for Alpha To Coverage, needs some more fixing until it works on all supported platforms.
Added support for Anti-Aliasing modes per material
Added an ICollisionCallback to ISceneNodeAnimatorCollisionResponse, to inform the application that a collision has occured. Thanks to garrittg for this.
Added an startPosition parameter to createFlyCircleAnimator() to allow starting the animator at any position on the circle.
Many uses of dimension2d changed to dimension2d, including IImage, ITexture and screen dimensions. You will have to change (at least) createDevice() calls to use dimension2d
Added Doublebuffer flag to SIrrCreationParameters, for better finetuning
Added Stereo-Framebuffer support for professional OpenGL cards
Added IFileSystem::createMemoryWriteFile() to allow creation of an IWriteFile interface that uses an application supplied memory buffer.
Added an IVideoDriver::writeImageToFile() overload that can take an IWriteFile interface.
(Internal) Replaced CMemoryReadFile with CMemoryFile, that also implements an IWriteFile interface.
Added an optional light manager to the scene manager to allow the user application to turn lights on and off during scene rendering. This can be used to produce "zoned" lighting. See example 20.ManagedLights.
Added a method to flip the Y movement of the FPS camera.
The Anisotropy filter can now be set to the AF value per texture layer. So no forced MAX_ANISOTROPY anymore. .irr files will probably fail, though.
AntiAlias parameter in SIrrCreationParameters is now an u8 value specifying the multisampling level (0 for disabled, 4,6,8, and others for anti-aliasing)
D3D devices use DISCARD for windowed renderbuffers now, can be faster.
Changed behaviour of PixelBlend16() / PixelBlend16_simd() so that they treat the 1 bit alpha of the source pixel as boolean, i.e. they draw either the source pixel, or the destination pixel, rather than "blending". (Issue revealed by the fix to IVideoDriver::makeColorKeyTexture()).
IVideoDriver::makeColorKeyTexture() bug fixed so that only alphas, not whole texel colors, are zeroed. An optional parameter allows using the old (buggy) behaviour for backwards compatibility.
position2d is now a synonym for vector2d. position2d is therefore marked as deprecated, although it's unlikely to be removed.
ISceneNodeAnimator now has a hasFinished() method.
ISceneNodeAnimatorCollisionResponse exposes the target node. Setting the node again resets the last position, allowing the node to be teleported.
Add a hitPosition out parameter to ISceneCollisionManager::getCollisionResultPosition() - this is a (small) API breaking change.

New in Irrlicht Engine 1.5.2 (Mar 19, 2012)

New in Irrlicht Engine 1.5.1 (Mar 19, 2012)

Make sure a missing font does not corrupt the skin.
Fix getAngle in vector2d as suggested by xray. This has only a minor impact on s32 vectors.
bugfix: CGUIFont::getCharacterFromPos regards now kerning (found by Arras)
Add support for range fog in some OpenGL versions.
Fix for shadow volume removal, submitted by vitek.
Avoid using X11 autorepeat to deal with broken X11 versions.
Speculars are properly exported into mtl files now, instead of corrupting them.
Binary type loading in attributes fixed.
bugfix: Use make_lower throughout for spritebank filenames (found and patched by Ion Dune)
STL loader fixed: Right-handedness corrected, normals and bboxes are correctly added now.
bugfix: CUnZipReader::openFile no longer returns true for empty files. Corresponding test added.
Big endian issues in .x loader fixed.
HSLColor methods repaired.
copyToScaling fixed.
Fixed problem with highlighting menus when mouse was outside sub-menu area.
bugfix (2796207): menu acted (wrongly) on left-click down instead of left-click up.
bswap16 fallback macro fixed
getBaseName fixed to work correct with dots in filenames.
static method isDriverSupported allows for simple check of available drivers.
Some defines added to check for the Irrlicht version of the library.
Make sure all renderstates are properly initialized
Wrong size for main depth buffer fixed.
Fix 3ds shininess to the allowed range.
Fix loading of Collada files from irrEdit 1.2
Remove texture pointers after texture clear.
WindowsCE pathnames fixed.
Some virtuals are now overridden as expected.
Incomplete FBOs are properly signalled now
Update to libpng 1.2.35, fixed issues on 64bit machines with system's libpng.
Fixed wrong grab/drop in setOverrideFont
Added draw2dRectOutline
rectf and recti added.
Fix ALPHA_CHANNEL_REF to a fixed check for alpha==127 as expected.
Fixed OSX device bug where screen size was not set in fullscreen mode.
cursor setVisible changed to be called less often.
OpenGL version calculation fixed.
OSX device now supports shift and ctrl keys.
Fixed ambient light issues in burningsvideo.
device reset for d3d fixed when using VBOs.
Fix dimension2d +=
MD2 mesh loader: Now uses much less memory, reduced number of allocations when loading meshes.
OpenGL render state (texture wrongly cached) fixed.
Fixed animator removal.
Checnged collision checks for children of invisible elements to also be ignored (as they're actually invisible due to inheritance).
Fix terrain to use 32bit only when necessary, make terrain use hw buffers. Heightmap loading and height calculation fixed. Visibility and LOD calculations updated.
Some mem leaks fixed
FPS camera resets the cursor better

New in Irrlicht Engine 1.5 (Mar 19, 2012)

Construction calls for FPS camera changed to take speed in units/milliseconds, just as the setSpeed method does.
Code::Blocks workspaces added. C::B projects (using gcc) now output to /lib/gcc and /bin/gcc, when built on either Windows or Linux.
Added a test suite in the /tests directory. This can be used to perform regression tests, and should be updated with new tests to verify fixes or validate new features.
Changed the preferred way of altering light node's radius: Use the new member methods of ILightSceneNode instead of directly modifying the SLight structure.
Changed the initial attenuation back to (0,1/radius,0). To override this value simply change the attenuation in the SLight (lightnode->getLightData().Attenuation.set(x,y,z))
Dirty fix for OSX device setResizable and a bug fix to do with resizing the device.
Terrain heightmap and texture were flipped in order to draw them as expected (looking onto the terrain from high above will just look like the actual texture/heightmap).
Significant internal change to the way that FPS camera jump speed and collision response animator gravity interact. The behaviour is now much more realistic, but it will require you to adjust your jump speed and gravity.
Skybox won't be culled anymore by nearplane or farplane.
BBoxes of animated meshes (skinned meshes) are updated again.
Lost devices (as found with D3D) are properly handled now. So the screen can be resized or minimized without crashing the app.
Renamed IGUIElement::setRelativePosition(const core::rect& r) to IGUIElement::setRelativePositionProportional(), as it has radically different functionality from setRelativePosition(const core::rect& r)
Added IGUIElement::setRelativePosition(const core::position2di & position) to set a new position while retaining the existing height and width.
Many Collada fixes. z_up coords are supported now, texture coords are properly loaded. Transparency is supported.
Camera scene node rotation and target can now be bound together so that changing one automatically changes the other (as the FPS camera has always done). See ICameraSceneNode::bindTargetAndRotation()
Removed the extra libpng files for OSX. OSX now also uses the default libpng.
Enhanced PCX support with some more color formats and write support.
Fixed LMTS problems with extra data in files.
Removed VS6 .dsw / .dsp project files - VS6 is no longer supported.
Particles can be scaled during animations. Particle scaling needs to happen in the emitter now, instead of in the Particle system scene node. Deprecation methods will guide the user.
ISceneNode::setParent and addChild now updates node SceneManager pointers if the node was from another SceneManager.
Basic support for joystick input events on Windows, Linux, SDL and OSX. Tested with wired Logitech and Thrustmaster wired controllers and XBox 360 wireless controller ( http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver )
Fixed scaled octree nodes being incorrectly frustum culled.
FSAA under OpenGL and Win32 added. Now all hw drivers and platforms should support it.
Unlimited RTT fix for D3D systems. Depth buffers are now shared if possible, otherwise a new depth buffer is generated. In order to save VidMem one should create RTTs starting with the largest one.
Avoid RTTs with nonFBO-support under OpenGL which are larger than the screen. Since we rely on rendering into textures in this case we need to clamp the size by the screensize.
Fixes for getAbsoluteFilename under Linux in order to return a filename instead of en empty string in case the file doesn't exist.
Use absolute path names when creating / finding textures.
Font tool implementation for Linux with xft, by Neil Burlock.
Support for normals and UV coords from DeclData in .x files.
Modified line2d::intersectWith() to cover more cases.
Added IVideoDriver::drawPixel().
Moved the window pointer from endScene to beginScene, as this is required for OpenGL support of external window pointers.
Fix for terrain culling.
Added minimize button to win32 window (if resizable)
Major API change: RTTs are now created via addRenderTargetTexture instead of createRenderTargetTexture, which allows to retrieve them from the texture cache, but also changes the way of removing the RTTs, and especially one must not drop the pointer anymore.
WindowsCE-Bugfix
disableFeature can be used to override feature support of the video driver.
draw2DImage can now also handle RTTs under OpenGL (which were flipped before).
Ogre mesh format fixes for proper texture support.
Added .obj mesh writer.
Some core::string constructors made explicit to avoid unintended conversions. Just add core::stringc() or core::stringw() around the old code to avoid warnings.
IdentityMatrix is now a properly defined global, with external visibility on all platforms.
Bugfix for context releases with glx 1.3 on error.
Removed constraints for sizes of the terrain scene node.
Support for 32bit indices in a special MeshBuffer class.
isBetweenPoints return true now even for the begin and end points, i.e. line segments are now including their start and end.
Fix XML reader creation for non-existing files and invalid callbacks.
Changed interpretation of MaterialTypeParam==0 in transparent materials. Now it's consistent with all other values, but one has to set the value to 0.5 to get the old behavior (slightly faster rendering, but no smooth borders)
Replaced transformBox by transformBoxEx in some internal methods to avoid major malfunction of the transformations.
Fix use of zip file inside zip files.
Avoid loading textures which are not used by the mesh in b3d loader.
Added scaleTCoords methods to MeshManipulator
Enable use of other meshes for shadow mesh generation, can be used to speed up shadow generation and rendering for complex meshes. Patch based on a version by tonic.
Fixed usage of SIrrCreationParameters struct, which dind't have copy constructor and assignment operator anymore, since the Irrlicht version string was made const.
New glext.h (version 41) and glxext.h (version 20) supporting OpenGL 3.0
Added support for read-only locking of textures. Can speed up those calls.
Added support for locking RTTs under OpenGL.
Implementation of UserData events from system events.
ICameraSceneNode::setIsOrthogonal replaced by a parameter to setProjectionMatrix.
All meshbuffers are now dynamically allocated to avoid problems with grabbed buffers, which may be deleted before the last drop happens (due to static memory allocation).
Enhanced scene graph traversal with example from rogerborg.
FPS camera disabling of event receiver works better now.
scene deserialization allows for a user defined callback after a new scene node is created.
Fixed tangent mesh loading from .irrmesh files.
OpenGL clamp modes are now properly set.
IMeshManipulator::transformMesh renamed to transform, also supports meshbuffers now.
scaleMesh renamed to scale, supports meshbuffers as well.
vector3d::rotationToDirection added.
New mesh generators for cone and cylinder.
Hardware accelerated Vertex and Index Buffer support finally integrated into Irrlicht. Thanks to a resource handling idea by Klasker and the almost immediate implementation by Luke, Irrlicht now supports VBOs under OpenGL and D3D.
Hardware buffers make rendering the same vertices much faster. To use this feature with a mesh, simply set a usage type via MeshBuffer->setHardwareMappingHint(scene::EHM_STATIC). The driver will upload the vertices and indices on the next draw and reuse this information without the need to upload it each frame.
Vertex and Index buffers can also be updated separately, which is e.g. useful for the terrain node's LOD.
Changed FBO creation according to Nadro's patch. Seems to have zbuffer problems currently.
Update to libpng 1.2.29
Compiler flag for PerfHUD support added.
recalculateNormals and tangent space creation enhancements by ryanclark.
Added getColorFormat methods for device and driver, returning the color format of the device's window and the driver's framebuffer.
Added isFullscreen method.
Added isWindowFocused and isWindowMinimized methods.
Screenshots are now always made from the frontbuffer, so always the last completely rendered image is captured. However, overlapping windows may corrupt those parts of the screenshot (as was previously happening with d3d already).
New device creation parameter to disable Irrlicht's system event handling.
New device creation parameter to specify depth bits.
New device creation parameter to request alpha channel in framebuffer.
Draw2DImage methods under OpenGL now also handle RTTs correctly.
Fixed RTT bug which lead to strangely clamped textures.
Speed improvement for screenshots on some Intel cards under OpenGL.
My3D file loader fixed.
Terrain mesh performance increased.
Fixed mem leak in cube node.
Compiler errors in shaders won't corrupt the material renderer list anymore.
Quake3 shader files now have properly working texture matrices again.
FPS and Maya style cameras are now standard cameras with a special animator.
ISceneNodeAnimator now inherits IEventReceiver
New method ISceneNodeAnimator::isEventReceiverEnabled, returns false by default
CCameraSceneNode::OnEvent passes events to animators with enabled event receivers
ISceneNodeAnimatorCameraFPS and ISceneNodeAnimatorCameraMaya interfaces for changing camera settings at run-time.
Changed SExposedVideoData to use void* instead of s32. Fixed 64bit portability.
Added support for front face culling.
Fix for HLSL shaders in one file.
Billboard::setColor bug fix by rogerborg.
Scene node sorting uses squared distances now.
Enhanced API for hte math functions. Many of them will now return a reference to *this for chained method invocations.
prevent .x loader to load .xml files.
AntiAlias support for OSX device.
Period character handling bug fixed.
New filesystem methods for filename handling.
added getVideoModeList and getDesktopResolution support for OSX
Octree supports tangent meshes now. Some performance improvements for the generation.
Fix mouse pointer and fullscreen mode problems in OSX.
Make cube and sphere scene node a mesh scene node (for access to the cube/sphere mesh).
Support for normal maps in 3ds files. Mem leak fixed. Loading for files with keyframe data fixed.
BillboardTextSceneNode is now an IBillboardSceneNode and an ITextSceneNode.
Support for external windows under Linux.
.X loader bug fixes.
Better debug visualization for MeshSceneNodes.
Fixed bug in material serialization when using the NullDriver.
Fix for Win32 CursorControl::setVisible
Support for LWO files.
Support for Collada 1.4 files.
Better and faster terrain smoothing by Frosty Topaz.
Fixed a performance bug in ISceneNode constructor reported by izhbq412
Win32 device now makes the cursor invisible immediately when setVisible(false) is called.
Command line tool for mesh conversion added.
Added volume light scene node
.obj files now won't duplicate vertices unnecessarily. This allows recalculation of smooth normals and other things, and is also faster when rendering. The loading is a little slower now.
They also support normal maps and texture clamping now. Group support added, can be ignored via scene manager attribute scene::OBJ_LOADER_IGNORE_GROUPS.
Normals will be calculated if the file doesn't provide them.
Better fix for hires timers on dual core machines by RogerBorg
added Initial Windows Mobile 6 Version.
Windows Mobile 6 SDK
Visual Studio 2005
Added checks to avoid buffer overrun in b3d loader. Enabled normals calculation in all cases, previously it was not done for lightmapped meshes.
Fixed transparency support. Added mipmap creation flag support which might disable mipmap creation too often. Should be checked.
Burningvideo: MipMap Selection repaired
renamed private Driver function getTextureSizeFromImageSize to getTextureSizeFromSurfaceSize
Added collision manager speedup patch by RogerBorg.
D3D drivers now releases the IImage member from initialization, thus freeing lots of memory. The image is accessible via the driver anyway.
SDL device character handling enhanced.
MeshBuffers can now access the elements of the S3DVertex base class in all vertex types directly, instead of using the getVertices() pointer access. This simplifies simple mesh manipulations as it does not require a switch statement over all vertex types.
More OpenGL renderstate bugs fixed
GLSL changes for setting arrays. Also allow for only pixel or vertex shader to be set.
Bugfix for removeChild in AnimatedMeshSceneNode.
Some bugfixes for Joint handling and skinned meshes. Added getJointCount in IAnimatedMeshSceneNode and isStatic in ISkinnedMesh.
Added WAL image format support based on the original loader by Murphy McCauley, written for Irrlicht around version 0.7.
OpenGL RTTs now also support alpha values.
New method driver->getVendorInfo() to query information about the actual hardware driver.
Fixed somed CQuake3ShaderSceneNode problems.
Changed BurningsVideo internal Vertex Format. version changed to 0.39
SceneManager:
Removed the seperate rendering states for quake3 Shader Scene Nodes.
Nodes are now solid or transparent. ( but still more states are needed )
GUI:
Editbox didn't draw children
Checking IsEnabled is now consistent across all GUI elements
Move window to front bug fixed.
Disabling the BMP loader now compiles without the built-in font
Added setTextAlignment to IGUIComboBox
Avoid dropping skin pointer which is in use.
Better warning for fonts without regions (sometimes wrong file is loaded by the user).
Fixed a bug in CGUISpriteBank which caused a crash when a non-looping animated sprite reached the end of its animation.
Modal screens no longer flash invisible children when rejecting a focus change.
Finally added StarSonata patch with table element and TabControl additions. Table is based on MultiColor listbox by Acki, and has loads of changes by CuteAlien.
