Assignment 8

Direct/Indirect Lighting

Direct/Indirect Lighting of the Cornell Box. I use RGB (for now).

These images use whites that are purely achromatic (red = green = blue), which is why they are not as brown or yellow as those of other people in the class.

(May be off by a factor of pi here somewhere . . . )

4 samples/pixel, 4 shadow rays/hit, 20% chance of absorbing indirect ray at each step.

4 samples/pixel, 4 shadow rays/hit, 10% chance of absorbing indirect ray at each step.

8 samples/pixel, 8 shadow rays/hit, 20% chance of absorbing indirect ray at each step.

8 samples/pixel, 8 shadow rays/hit, 10% chance of absorbing indirect ray at each step.
