Metal Performance Shaders (MPS) harnesses the massive parallelism of the GPU to dramatically accelerate calculations at the heart of modern ray tracing and ray casting techniques. See how ray tracing can provide greater realism in 3D scenes through improved shading, soft shadows, and global illumination. Understand how MPS accelerates ray-triangle intersections while enabling dynamic scene updates, and learn how to extend your app across multiple GPUs for even greater performance.
