Open Asset Import Library (assimp)
==================================
Open Asset Import Library is a library that loads various 3D file formats into a shared, in-memory format. It supports more than __40 file formats__ for import and a growing selection of file formats for export.

APIs are provided for C and C++. Various bindings exist to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.
Additionally, assimp features various __mesh post-processing tools__: normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials and many more.
