smoke-metal-skin-cse457

This project extends the RayTracingInOneWeekend Book 1 path tracer with CPU multithreading, CUDA and OptiX support, and new geometry and materials such as cubes, emissives, and volumes. Created by Group K: Advanced Raytracing, UW CSE457 SP23

Requires Boost, libpng16, for CPU backend.

Requires stb_image, g++12 (nvcc 12.x is not currently compatible with g++13), CUDA 12.x, and OptiX 7.x for the two GPU backends.

Edit set(OptiX_INSTALL_DIR /opt/optix) in CMakeLists.txt:37 to point to your OptiX install directory.

Currently resolution and sample count are hardcoded but they can easily be changed by editing the screenInfo values at the top of main.cpp and rebuilding.

Building

1. Ensure appropriate dependencies are installed
2. Create and cd into a build directory (mkdir build && cd build)
3. Run cmake ..
