Monte-Carlo-Raytracer with Radeon Rays and OpenCL 1.2

Features

• Regular Path Tracer
• Bidirectional Path Tracer
• Light Sources
  • Directional Light
  • Point Light
  • Area Lights
• GUI with editable Scene
• Uber Material
  • Glossy Reflection and Transmission: Torrance-Sparrow Microfacet BRDF and BTDF with a Trowbridge-Reitz distribution for dielectrics
  • Specular Transmission
  • Specular Reflection
  • Lambertian Reflection
  • Normal Mapping
• Currently a random sampler is used however it can be changed to Sobol via #define in assets/kernels/samplers.cl

Build

• git clone --recursive https://github.com/compix/Monte-Carlo-Raytracer.git
• CMake - Currently only Windows is supported, minor modifications need to be made to support Linux.
• Tested on Windows 10, compiled with Visual Studio 2017 (which has built in CMake support)
