A (small) raytracer and pathtracer using MLX, the graphic library of 42.
GPU utilization is forbidden in this project. To enhance our goal of achieving smooth movement and fast rendering, we implemented multi-threading, pixel shuffling, and an optimized rendering mode during motion. This approach not only improves performance but also ensures a seamless visual experience.
