Temporally Adaptive Ray Tracing Decomposition
using MPI

• Rafal Zboinski

2
Basic Ray Tracing

• A rendering technique used to generate realistic
  scenes
• Rays are shot from a view point (the eye) into
  the scene

3
Ray Tracing (cont.)

• Different Materials combined with scene geometry
  orientation make ray tracing unbalanced
• Advanced Ray Tracing Techniques
• Shoot out multiple rays to solve rendering
  artifacts due to basic ray tracing method
• Increases computational complexity of rendering
  and variability of complexity between pixels
