CocosSharp is a C# implementation of the Cocos2D and Cocos3D APIs that runs on any platform where MonoGame runs (https://github.com/mono/CocosSharp ).
Cocos3D can probably load a model/scene created in 3ds Max.
My questions are:
Can I use XF together with Cocos3D?
Are there any alternatives to load a 3D Scene in XF and render it with OpenGL without doing the heavy lifting stuff of writing an object loader and Rendering-Code?
