    - Built and tested with the DAE importer, seems to work fine.

Open Asset Import Library (assimp) 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. 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.
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. According to [Travis-CI] (https://travis-ci.org/), the current build status of the trunk is [![Build Status](https://travis-ci.org/assimp/assimp.png)](https://travis-ci.org/assimp/assimp) APIs are provided for C and C++. There are various bindings to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.
