Ray tracing

Based on: Ray Tracing In One Weekend

Local Setup

1. Install cmake, a C++17 compiler, and the CUDA toolkit v12.1
2. Build the project.

   cmake -DCMAKE_BUILD_TYPE=Debug -B out/build
   cmake --build out/build --config Debug

   Or replace Debug with Release if you want a release build
3. Run the project.

   ./out/build/raytrace

4. Alternatively, if you're using VS Code, there's quite a good cmake extension you can use for bulding and running the project.

Discalimer

The CUDA SDK is tightly coupled system type and hardware specifications, meaning there is no guarantee of this project working on platforms which it hasn't been explicitly tested.

The project has been tested on Ubuntu 22 with an Intel CPU, and a Geforce 1660ti.

If the project is incompatible with your machine, or if you'd prefer not to download the CUDA sdk, this project also contains an implementation for running on the CPU, which should hopefully be more consistent across platforms.
