radiance_cascades_2d

2D implementation of Radiance Cascades (invented by Alexander Sannikov)

To-Do (vaguely ordered by priority and ease of implementation)

• Interval overlap: how much of the next inverval overlaps with the previous one (0 to 1)

• Free allocated stuff

• Bilinear filtering

• Save resulting render to file

• Single texture for all of the cascades (they will need to vertically fill the texture)

• Move cascades calculations on the gpu

  • cascades creation
  • cascades merging

• Calculate cascades for each frame (moving objects)

• Setup benchmarking environment

  • Test cases
  • Logging
  • Data visualization

Investigate

• Different memory layouts

  • for each cascade, probes are adjecent (default)
  • for each cascade, every direction ray data is adjecent

• Build and merge at the same time, starting from last cascade
