Notes

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

Final Scene

An image of the final rendered 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).
