This is small educational raytracing renderer from C++ course at MIPT. It is based on "Ray Tracing in One Weekend" article, but with better architecture and code quality.
To change render parameters you should see include/config.h. It is possible to render and save as file or display the image
on the screen (see PREVIEW_MODE), but keep in mind that a quality render takes ~15-20 minutes on Ryzen 5700X,
so the preview parameters should be much lower.
The scene itself is defined in src/main.cpp.
It it powered by CMake -- so I hope you will figure it out how to compile it by yourself
