ReSTIR lajolla

This is an implementation of ReSTIR with spatial reuse in lajolla, UCSD CSE 272 renderer.

Build

All the dependencies are included. Use CMake to build. If you are on Unix systems, try

mkdir build
cd build
cmake ..

It requires compilers that support C++17 (gcc version >= 8, clang version >= 7, Apple Clang version >= 11.0, MSVC version >= 19.14).

Apple M1 users: you might need to build Embree from scratch since the prebuilt MacOS binary provided is built for x86 machines.

Run

The test scene is located at scenes/restir_test_scene/test.xml. Please directly change the parameters to tune the result. Try

cd build
./lajolla ../scenes/manylight/test.xml

This will generate an image "image.exr".

To view the image, use hdrview, or tev.
