A customizable NVIDIA PhysX SDK wrapper library for C# and other .NET framework languages. Compatible with XNA, Mogre, Truevision3D, SlimDX, Tao framework, and your own math library.
Very nice to be able to use this in .net. Works great, I've had no trouble getting this to work. Porting the existing samples was pretty straight forward. Personally I use Mogre (managed ogre3d ). Only thing I think is missing is a sample scene with serialization.
