Image Synthesis Class

Homework 7:

Implement implicit indirect lighting and show the results using the Cornell Box.

NOTE: All images are gamma corrected with gamma 2.


Indirect lighting in the Cornell Box
with 64000 samples per pixel.

Light Intensity: Low
(Spectral Values: 1)
Light Intensity: Mid
(Spectral Values: 2)
Light Intensity: High
(Spectral Values: 3)
Rays per pixel: 15625
Rays per pixel: 4096
Rays per pixel: 2197
Rays per pixel: 1000
Rays per pixel: 343
Rays per pixel: 64

Contribution of Various Ray Depths:

Below is a comparison of the contributions of various depths. Depth 1 is just light sources, depth 2 is direct lighting, depth 3 is one bounce indirect lighting, etc.


Depth: 1

Depth: 2

Depth: 3

Depth: 4

Depth: 5

Depth: 6
