Reservoir logic for understanding spatio/tempral resampling.
ReSTIR, or Spatio-Temporal Reservoir Resampling, is the mathematical basis for a new generation of Ray Tracing engines. This new generation aims to produce photo-realistic images in real-time by using smart math for re-using the previous computations.
Understanding it is key to try yourself in this new area. However, diving into the research papers can be challenging. To help, I created this repository to implement the basics of reservoirs in Rust.
Example light evaluation in 2D using ReSTIR:
