The image on the left is of the Stanford Happy Buddha, with 543,652 vertices and 1,087,716 triangles. On the right is the Stanford Dragon with 437,645 vertices and 871,414 triangles. Both models were downloaded from http://www-static.cc.gatech.edu/projects/large_models in ply format.

Design Choices

Below are some of the design decisions I made:

I decided to implement a grid acceleration structure because it was recommended in class and it was an extension of the heightfield.
The acceleration structure is added to the group, which is then added to the scene. Individual objects are added directly to the structure, so that the user has control over what is included in the acceleration structure.
I also changed my value of epsilon to 1.e-8 instead of using 1.e-4 because the triangles of the mesh are so small.

Extra Credit

I didn't implement the extra credit.
