+Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a single, in-memory format__. It supports more than __30 file formats__ for import and a growing selection of file formats for export. Additionally, assimp features various __post processing tools__ to refine the imported data: _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.
