Ray Tracing and Path Tracing with NVIDIA OptiX

12/27/2020 ray-tracer

• Implemented simple ray tracer with NVIDIA OptiX
• See INSTALL-LINUX/WIN.txt for compile instructions
• Tested version:
  Windows 10: CUDA 10, OptiX 6.5; Ubuntu 20.04: CUDA 10.2, OptiX 6.5
• Used native GeometryTriangles and self-defined Sphere for geometry primitives
• Blinn–Phong shading model, recursive trace for mirror reflection

     

12/29/2020 path-tracer-light

• Solve render equation for direct area lighting
• Modified Phong BRDF
• Monte Carlo integration with stratified sampling
