A small path tracing renderer written in Rust.
Branch: master
Clone or download


This is a CPU-based path tracing renderer focused on rendering SDFs, specifically fractals. It was originally based on the book "Ray tracing in one weekend" by Peter Shirley, which I heartily recommend, though it has now evolved into a structure of my own design, taking hints from both that and pbrt, which is also an excellent reference.


  • Architected to use 128-wide SIMD to full extent with the help of ultraviolet, and in the future perhaps 256 or 512 as well.
  • Physical light transport algorithm
  • Depth of field
  • Arbitrary animation and time-sampled motion blur
  • Importance sampling (soon multiple importance sampling)
  • Multiple-bounce indirect lighting/global illumination
  • Signed distance field rendering through leveraging sdfu
