Open Asset Import Library (assimp)
==================================
A library to import and export various 3d-model-formats including scene-post-processing to generate missing render data.
Open Asset Import Library is a library to load 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.
