From the report:
The project applies Monte Carlo integration and ray-tracing techniques to calculate complex light interactions within a 3D scene, including reflections, refractions, and diffuse color >bleeding. The model, developed in C++, is designed to handle multiple light bounces, allowing for accurate simulation of indirect lighting. Results demonstrate the renderer’s effectiveness in >creating realistic images, though at a high computational cost.
