Overview

RTVK is a Vulkan ray-tracing renderer I’m developing to study and experiment with light-transport methods. It currently loads glTF scenes, creates acceleration structures, and traces rays using path tracing and Monte Carlo sampling.

Highlights

  • Vulkan hardware ray tracing with BLAS and TLAS
  • glTF scene and physically based material support
  • BSDF importance sampling and next-event estimation
  • Transmission, alpha materials, and normal mapping
  • Ray-cone texture filtering, exposure, and tone mapping
