Description
Add path tracing with an arbitrary number of bounces.
Reflected Light
Note how light bounces between the spider and the floor, allowing red light to reach the shadowed area of the floor and illuminating the underside of spider's legs. This image was created with 625 samples per pixel, jittered sampling with cubic b-spline filtering, and a maximum of 10 bounces per ray. Compare this to my single bounce images.
Convergence
Just a couple more images to show how this picture converges.
64 samples per pixel
256 samples per pixel
