Part 8/10:
Despite the iterative advances, creating a single animation frame still demands an astronomical number of rays for accurate results. Here, bounding volume hierarchies (BVHs) come into play, significantly enhancing efficiency by organizing triangles into manageable bounding volumes, streamlining intersection calculations.
Today's GPUs are astonishingly powerful, capable of performing tens of trillions of operations per second due to specialized cores designed for ray tracing. This technological progress has made real-time rendering feasible in video games and significantly accelerated CGI workflows in films.
