The project is organized as follows:
- Includes: Contains the header files.
- Src: Contains the source files.
- plugins: Contains source code for plugins.
- Assets: Contains assets usable for configurations.
- Doc: Contains the documentation.
- scenes: Contains the scene
.cfgfiles.
The project can be built using the provided Makefile. To compile the source code and produce an executable named raytracer, run the following command in the terminal:
makeWe use libconfig++ for parsing config files (.cfg). Below is an example configuration for a scene:

aspectRatio = 1.0;
imageWidth = 400;

adaptativeSupersampling = { activated = true, threshold = 10.0 };
}
