The bunny scene makes use of the Stanford Bunny from the Stanford 3D Scanning Repository.
The reference image was rendered with one sample per pixel
Render times were measured using
std::chrono::high_resolution_clock and only include time to render,
ie. time to load the scene and write the images to disk is ignored. Both images were rendered with 8 threads and
8x8 blocks with 16 samples taken per pixel, sample positions were generated with a low-discrepancy (0, 2) sequence.
