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)
