AC3D description
AC3D - A 3D object and scene modeler

AC3D is a program that will help you to view, edit and create 3D graphics with this popular 3D object/scene modeller, available for Windows and Linux (previous versions for SGI, Solaris and HP also available). AC3D is very easy to use but powerful too.

Here are some key features of "AC3D":

· Simple, intuitive 'click and drag' user interface
· Truetype font 2D and 3D text generator
· Integrated graphical texture coordinate editor
· Fast subdivision surface modeling
· Many 3D file formats supported

Specifications:
· Fast real-time OpenGL graphics views (2D and 3D)
· Multipoint polygon and line editing down to vertex level
· No polygon limits
· Extrusion and surface revolution
· Software development kit and plugin interface.
· Fast and memory efficient, compact program binary.
· Built-in fast OpenGL 3D renderer with adjustable field-of-view - instantly see results of your actions in 3D. Spin the model or switch into 'walk mode' for Quake-style control.
· Edit at different granularity - groups, objects, surfaces, vertices
· Full polygon editing. e.g create a sphere and easily move the points (vertices) to deform the shape.
· Create and edit multi-point polygons and lines - not just triangles.
· Manipulate individual surfaces: insert/remove vertices, make holes, spike, spline, bevel, triangulate, flip, subdivide
· Texture mapping support with real-time rendering.
· Texture/background image file formats supported: GIF, JPG, PNG, BMP, DDS, PPM, TGA (Targa), TIF
· Graphical Texture Coordinate Editor (UV Mapper)
· Assemble surfaces into new objects
· 4 views - 3 orthographic and one 3D. All atonce or individually.
· Named objects can be searched for within a scene
· Navigate/Zoom around the 2d views with cursor keys and other single key presses
· Hierarchical view window
· Hide/unhide objects for easier/faster editing of complicated scenes
· Headlight and up to 7 other positionable lights
· 24-bit colour palette with adjustable diffuse; ambient; emissive; specular; shininess and transparency
· Adjustable 2D and 3D grid guide lines with grid-snap function
· Create new surfaces/objects around any selection (Convex hull)
· Configurable to use external renderers such as Povray and BMRT - just select Tools->Render to start
· Multi platform program - AC3D file format compatible across platformsAttach URLs to objects for use in VRML files
· Attach string data to objects to be used as scripting in Dive or special directives for POV or renderman
· Supports many output/input formats including: 3D-studio 3DS, Lightwave LWO, Alias triangle, DXF, VRML1 and 2 and Inventor, Povray, Renderman RIB, Triangles, Direct X, Milkshape, Quake 3 bsp, MD2, Wavefront OBJ, OFF, stl (ascii), sof (airfoil), SMF, T3D, LDRAW .ldr (Lego)
· Extrude and revolve 2D lines to make 3D shapes
· Scale a selection to a specific size
· Flip a selection (mirror) about X, Y or Z axis
· Remove duplicate vertices and surfaces ('optimize')
· Simple documented file formats allow easy conversion from other forms of data - ideal for visualizing your own data in 3D
· Developer SDK


Requirements:

· Pentium 120 (or equiv) minimum
· 64 MB RAM minimum
· 10 MB free hard disk space
· preferable, but not necessary - 3D accelerated video card with OpenGL drivers


Limitations:
