ASSIMP currently supports the following file formats. Note that the library does not always support all features of a format.

CAD/3D Modelling file formats

• 3D Studio Max 3DS ( *.3ds )
• 3D Studio Max ASE ( *.ase )
• Wavefront Object ( *.obj )
• Milkshape 3D ( *.ms3d )
• Polygon Library ( *.ply )

Game file formats

• Valve StudioModel ( *.smd,*.vta )
• Quake I ( *.mdl )
• Quake II ( *.md2 )
• Quake III ( *.md3 )
• Return to Castle Wolfenstein ( *.mdc )
• EliteForce II ( *.mdr )
• Doom 3 ( *.md5 )

Other file formats

• DirectX X ( *.x ).
• 3D GameStudio ( *.mdl )
• 3D GameStudio Terrain ( *.hmp )
  (All sub versions of 3D GameStudio models/terrains are supported: mdl2, mdl3, mdl4, mdl5, mdl7, hmp4, hmp5, hmp7)

Real-time rendering

• OpenGL to DirectX conventions.
• Limit bone weights per vertex. Useful for hardware skinning
• Triangulate higher-level polygons. (*)
• Remove redundant vertices.

Compute Vertex components

• Per-face normal vectors. "Flat shading"
• Per-vertex normal vectors. "Smooth shading"
• Tangents and bitangents. Required for Normal Mapping

Scenegraph

• Remove scenegraph. Transform all vertices into worldspace
• Optimize the graph. Remove small nodes and too deep hierarchies

Other

• Validate the output structure. For extra stability
• Check for infacing normals.
• Kill imported normals. Force a recomputation.
• Split large meshes. Both a vertex and a triangle limit can be set.

(*) = Always active in jAssimp. There is no support for polygons in this port.
