This repository hosts the code that was developed alongside with the masters thesis "Comparison and Evaluation Of Modern Sampling Techniques For Realtime Ray Tracing". The application was developed on top of the rapid prototyping framework "foray". The ReSTIR shadercode is based on https://github.com/lukedan/ReSTIR-Vulkan
Working as of the 16th of October 2023 with Vulkan 1.3.261.1.
- Vulkan 1.3.261.1 (Other versions not tested) Follow install instructions on https://vulkan.lunarg.com/sdk/home
- Clone the repository with its submodules.
git clone --recursive https://github.com/Vulkemp/foray_restir.git
Clones the repository and the foray submodule.
The repository contains three main scenes:
- emissive spheres
- pillar room
- bistro exterior
A scene can be chosen in the restir_app.cpp file by editing void RestirProject::loadScene() method. Simply comment in the desired scene path.
Due to size restrictions before using the bistro exterior scene, the gltf binary must be unzipped. Inside the path data/scenes/bistro_exterior the buffer.zip file must be unzipped, so the buffer.bin is available in the directory.
There are two apps available
- restir_app - Main application that shows the reservoir light sampling on the three available test scenes.
- sampling_testapp - Used for testing the other sampling methods. Only supports the emissive scenes scene.
