Repo link.

Highlights:
Finished path tracing core features:

  • diffuse shaders
  • perfect specular reflection
  • 1st-bounce ray intersection caching
  • radix sort by material type
  • path continuation/termination by Thrust stream compaction

Finished Advanced Features:

  • Refraction with Fresnel effects using Schlick's approximation
  • Stochastic sampled anti-aliasing
  • Physically-based depth of field
  • OBJ mesh loading with tinyobjloader

Used 1 late day.

Feedback:

  • Too many global variables across the base code which decreases code readability.
