cd build
cmake ../
### Build
cd ..
BuildDebug.bat / BuildRelease.bat
First build may take a while because it's going to build all the dependencies with the project.
This is the repository accompanying the blog post series "Simple GPU Path Tracing". It contains all the code that we write throughout the series. Each branch in this repo corresponds to a blog post.
Here's a summary of all the episodes in the series : Simple GPU Path Tracing : Introduction
Simple GPU Path Tracing, Part. 1 : Project Setup
Simple GPU Path Tracing, Part. 1.1 : Adding a cuda backend to the project
Simple GPU Path Tracing, Part. 2.0 : Scene Representation
Simple GPU Path Tracing, Part. 2.1 : Acceleration structure
Simple GPU Path Tracing, Part. 3.0 : Path Tracing Basics
Simple GPU Path Tracing, Part. 3.1 : Matte Material
Simple GPU Path Tracing, Part. 3.2 : Physically Based Material
Simple GPU Path Tracing, Part. 3.4 : Small Improvements, Camera and wrap up
Simple GPU Path Tracing, Part. 4.0 : Mesh Loading
Simple GPU Path Tracing, Part. 4.1 : Textures
Simple GPU Path Tracing, Part. 4.2 : Normal Mapping & GLTF Textures
Simple GPU Path Tracing, Part. 5.0 : Sampling lights
Simple GPU Path Tracing, Part 6 : GUI
Simple GPU Path Tracing, Part 7.0 : Transparency
Simple GPU Path Tracing, Part 7.1 : Volumetric materials
Simple GPU Path Tracing, Part 7.1 : Refractive material
Simple GPU Path Tracing, Part 8 : Denoising
Simple GPU Path Tracing, Part 9 : Environment Lighting
Simple GPU Path Tracing, Part 10 : Little Optimizations
Simple GPU Path Tracing, Part 11 : Multiple Importance Sampling
