The Stanford dragon, 500k triangles, rendered through the BVH in roughly ten seconds.
A CPU ray tracer I wrote in C over one semester, with no external dependencies. I wrote my own dynamic array, hash map, lexer, and scene file parser. Each assignment added a feature, starting with Perlin noise images and adding camera projection, Phong shading, texture mapping, triangle meshes, reflection, and refraction. A bounding volume hierarchy (BVH) splits each node at the midpoint of its longest axis. With it, the tracer renders the half-million-triangle Stanford dragon in about ten seconds.
