ACM SIGGRAPH 2005 Courses on - SIGGRAPH '05, 1999 We examine a rendering system that interactively ray traces an image on a conventional multiprocessor. The implementation is "brute force" in that it explicitly traces rays through every screen pixel, yet pays careful attention to system resources for acceleration.
