Path Tracer January 2015

1,488 Go 3D Graphics

CPU-only, unidirectional path tracing engine written in Go.

This was the first thing that I wrote using Go and I've been loving it ever since! The inspiration for this project came from Evan Wallace's WebGL Path Tracing.

  • Supports OBJ and STL file formats
  • Supports textures, bump maps and normal maps
  • Supports raymarching of signed distance fields
  • Supports volume rendering from image slices
  • Supports various material properties
  • Supports configurable depth of field
  • Supports iterative rendering
  • Supports adaptive sampling and firefly reduction
  • Uses k-d trees to accelerate ray intersection tests
  • Uses all CPU cores in parallel
  • 100% pure Go with no dependencies besides the standard library
