Project structure

raylib/  : Contains raytracing implementation. Built as a DLL.

           Select a demo scene, adjust rendering options, and execute raytracer.
gui-app/ : GUI version of the CUI app. Written in C# for practice.

How to build

1. Run Setup.ps1.
2. Build at the top level using CMake. This should build raylib and src.
3. Build gui-app. Copy FreeImage.dll, OpenImageDenoise.dll, raylib.dll, and tbb12.dll from raylib output to gui-app output directory.
