Object files (.obj) define the geometry and other properties for objects in Wavefront's Advanced Visualizer. Several other 3D graphics applications, including Alias Model, SoftImage, Autodesk 3DStudio support this format.
Although the .obj file format supports both polygonal objects and free-form objects, Ez3d objects are written out as polygon geometries with information on vertices, vertex normals, texture vertices and faces (connectivity) information.
Currently the following Wavefront primitives are handled:
o Polygonal Meshes
o Groups (it works best if the groups are unique, polygons belonging to more than one group will be duplicated in the Inventor file This will be improved for the release version. )
