Usage:

Compiling:

This project uses CMake to compile. To compile, run the following commands:

cmake -S . -B build
cmake --build build

Running:

To run the program, run the following command:

./raytracer

Config File:

The config file used to generate the image is located at the root of the project and is called config.cfg. The config file is a text file that contains all the information needed to generate the image. The config file is divided into sections, each section containing information about a specific aspect of the image. The sections are as follows:

• camera: Contains information about the camera used to generate the image.
• primitives: Contains information about the primitives in the scene.
• lights: Contains information about the lights in the scene.
• materials: Contains information about the materials used in the scene.
• AntiAliasing: Contains information about the anti-aliasing used in the scene.
