Notes

• Not optimised for efficiency.
• I use a slightly different method for refraction calculation (see first reference).

Final Scene

Rendered at: 2000px * 1333px, 500 samples/px, maximum depth of 50.

Future Work

• Rectangular parallelepipeds.
• Triangle support.
• Abstracting the description of scenes (maybe a DSL and custom file-format).
