Ray tracing algorithms

Definition

Ray tracing algorithms are computational techniques used to simulate the way light interacts with objects in a virtual environment, generating realistic images by tracing the path of rays of light as they travel through a scene. This method is particularly effective for visualizing complex structures, including fractals, as it allows for accurate rendering of shadows, reflections, and refractions that contribute to the depth and detail of fractal sets.
