Ray Tracer Part 5: Reflection

Single Reflection Ray on Mirrored Sphere

This assignment's focus was adding reflection to the Ray Tracer. Due to the size of my floor, I moved the reflective sphere around a little for a more aesthetic reflection. I also moved the light sources slightly to the center so the shadows would reflect in the back sphere.

I also implemented using multiple reflection rays to approximate a BRDF. Below you can see the results of some of these experiments.

 

6 reflection rays, in a cone-radius
of .005



8 reflection rays, with a cone-radius of .01
