It's a great Open Source C++ rendering engine that supports both DirectX and OpenGL, and a lot of 3rd party plugins exist.
Unfortunately I felt it was a bit slow, so I decided to rewrite Ainur to use Horde3D, a C based Open Source rendering engine that supports OpenGL.
It doesn't have the same 3rd party support that Ogre3D has, but it seems faster and lightweight when compared.
I still have the old source code so we will see if this Horde3D rewrite will succedes. If I will find some problems, I can easily switch back to Ogre3D.
