 Open Asset Import Library (assimp) 
 ========
 
-Open Asset Import Library is a Open Source library designed to load various __3d file formats and convert them into a shared, in-memory format__. It supports more than __40 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.

-This is the development trunk of assimp containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [assimp.sf.net](http://assimp.sf.net) or from *nix package repositories.
