DXTViewer

DXTViewer is a compressed texture viewer. It will let you easily visualize DirectDrawSurface file (*.DDS) and can save all usual formats (*.bmp, *.jpg, *.tga, ...) into DirectDrawSurface DDS or oZone3D O3TC compressed format. O3TC format can be used in Hyperion demos.

DXTViewer is a compressed texture viewer. These textures, mainly in DDS format (Direct Draw Surface), are commonly used in realtime 3D applications.

Compressed textures leads to increased procurement efficiency, due to two major improvements which are: less diskspace and video memory consumption and direct loading into the graphics video memory (no transformation stage required) Texture loading is dramatically increased even for high resolution images (4096x2048 for instance).

DXTViewer handles the following S3TC compression formats: DXT1, DXT3, DXT5 and ATI's 3Dc.

DXTViewer allows to load usual image formats such as JPG, BMP, TGA, PNG or GIF. These files can be converted in compressed textures in DDS (Direct Draw Surface) or O3TC (oZone3D Texture Compression) formats. The O3TC format has the same features than DDS (S3TC DXT1,DXT5 and ATI 3Dc), is really simple to load and is not Y-reversed like the DDS

Here are some key features of "DXTViewer":

￭ Use of OpenGL for texture rendering ￭ (GL_EXT_texture_compression_s3tc / GL_ATI_texture_compression_3dc extensions) ￭ Loading of *.DDS (DXT1, DXT3, DXT5 and ATI 3Dc ) format ￭ Loading of *.O3TC (DXT1, DXT5 and ATI 3Dc) format ￭ Loading of *.JPG, *.BMP, *.TGA, *.PNG, *.GIF, *.TIF, *.PSD formats ￭ Texture Saving in *.DDS (Direct Draw Surface) and *.O3TC (oZone3D Texture Compression) with DXT1, DXT5 compression. ￭ Normal-map compression: export in Swizzled-DXT5 or ATI's 3Dc compression ￭ Very fast texture paning and zooming

Requirements:

￭ Processor: Pentium III or AMD Athlon and up processor - 800 MHz and up. ￭ Memory: 256M RAM or higher ￭ Graphics Controller: ATI Radeon 9500 and up (with the latest Catalyst drivers) or GeForce FX 5200 and up (with the latest Forceware drivers)
