A raytracer written in rust.

Supports:

• Tracing (Integrator)

  • Whitted tracing
  • Path tracing with basic Monte-Carlo global illumination
    • Lambertian
    • Specular
    • Dielelectric

• Objects

  • Sphere
  • Plane
  • Mesh
  • OBJ file to mesh import
  • Infinite Mesh

• Skysphere with Rayleigh and Mie Scattering

• Procedural Objects

  • Ocean (Tessendorf's algorithm with Phillips spectrum)
  • Random Cubes

• Multithreaded

• Progressive rendering
