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
- 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
- Sandio 3D mouse support
- Locked objects can now be shown in full 3D (or wireframe as before) - see advanced settings
- Improved DDS loading
- Improved PNG support
- New Milkshape exporter from TFPsoft which uses the AC3D hierarchy to produce a skeleton
- ATI NMF exporter: turn your high-resolution model into a normal map for a low-resolution model. Works well with ATI’s NormalMapper
- Mac – Leopard fixes. Most Mac users should notice a speed increase with multiple views
