The super hard work I was doing Friday night that took soooooooo long and I had to change about 8 files in my Raytracer, and it was a good 600 lines of code added at least... it's ALL WORKING now!!!!! Yeeeeeeah!!
So this is an extension to my Voxel Traversal where I now subdivide the meshes into it's sub-pieces (triangles, polygons, etc) and treat those pieces as Primitives instead of treating the Mesh as a Primitive. This implies a monstrous increase in performance because now the Voxels can contain just a subset of the mesh instead of the *entire* mesh. This is totally sweet and I am super psyched that it's finally working.
The results.... the Venus De Milo mesh is rendering in 141 seconds (~2 minutes) as compared with 2752 seconds (~46 minutes) with the other version of the Voxel Traversal where the mesh is considered to be a Primitive. Awesome.
Here are some pretty pictures.
Cows scene now rendering correctly with my Voxel-Polygon optimization
Non-hierarchical scene now rendering correctly with my Voxel-Polygon optimization
Simple cows hierarchical scene now rendering correctly with my Voxel-Polygon optimization
