SharpAssimp

SharpAssimp is a maintained, modern fork of AssimpNet and AssimpNetter, the cross-platform .NET wrapper for the Open Asset Import Library (otherwise known as Assimp), which is a 3D model import-export library. The primary motivation is for this library to power (offline) content pipelines to import and process 3D models into your game engine's internal format, although the wrapper can be used at runtime to enable your users to import custom content. Please see the Assimp website for a full list of supported formats and features. Each version of the managed wrapper tries to maintain parity with the features of the native version.
