Notes

Unfortunately, I had an odd memory write error for scenes that were too complex or when I was computing too many rays per pixel (for super-sampling). I was therefore limited in the total complexity of my scenes. I broke up the most complicated pieces (a checkered floor and transparent spheres) as you can see in the examples below.

For super-sampling, I implemented a block filter for sizes 4 and 9.

Results

No anti-aliasing
4 sub-pixel rays

9 sub-pixel rays
No super-sampling, too complex

No anti-aliasing
4 sub-pixel rays

No anti-aliasing, turquoise ball reflective
4 sub-pixel rays

No anti-aliasing, turquoise ball refractive
4 sub-pixel rays

No anti-aliasing, floor non-reflective
No anti-aliasing
