MR File Format & .OBJ Importer

Importing a scene modeled in other programs is essencial to test my raytracer. Today I've finished the definition of a file format (.mr) capable of represent objects, normals, UVW maps, lights, shaders, camera and some rendering settings. I've also implemented an .MR parser and a .OBJ to .MR converter. Here is a render of gargoile with about 30.000 triangles:

This gargoile render took about 3 hours! I definitely have to implement some ray-object acceleration method soon! My next development will probably be a KD-Tree data structure...
