Realtime GPU Path Tracing engine based on OpenCL and OpenGL

Watch on YouTube

Features

• Unidirectional wavefront path tracer done entirely on GPU using compute shaders
• OpenCL backend
• OpenGL backend (WIP)
• Hybrid path tracing (rasterization of the primary visibility) in OpenGL mode
• Lambert diffuse, GGX reflection BRDF
• Explicit point, directional light sampling
• Simple temporal reprojection filter
• Depth, normals, albedo, motion vectors AOV generation
• Hot kernel reloading
• OpenCL/OpenGL interop for presenting the image

Pre-Requisites:

OpenCL SDKs

• NVIDIA CUDA Toolkit — for NVIDIA GPU
• AMD OpenCL™ SDK — for AMD GPU/CPU
• Intel® SDK for OpenCL™ Applications — for Intel CPU/GPU
