WebSep 1, 2013 · The surface area heuristic (SAH) is widely used as a predictor for ray tracing performance, and as a heuristic to guide the construction of spatial acceleration structures. We investigate how well SAH actually predicts ray tracing performance of a bounding volume hierarchy (BVH), observe that this relationship is far from perfect, and then … WebJul 5, 2024 · The first ray tracing algorithm used for rendering was presented by Arthur Appel in 1968. [1] This algorithm has since been termed “ray casting”. The idea behind ray casting is to shoot rays from the eye, one per pixel, and find the closest object blocking the path of that ray.
