This demo compute image by shooting rays from sceren to an object.
The demo repeats following two rendering modes:
- retro reflection: orthogonal projection direction and parallel light direction is aligned
- ambient occlusion
This demo has an implementation of the following paper:
"Fast parallel construction of high-quality bounding volume hierarchies",
Tero Karras and Timo Aila.
