 | Parker, Steven G.; Hansen, Charles D.; Shirley, Peter S. | Interactive ray tracing for volume visualization | We present a brute-force ray tracing system for interactive volume visualization, The system runs on a conventional (distributed) shared-memory multiprocessor machine. For each pixel we trace a ray through a volume to compute the color for that pixel. Although this method has high intrinsic computa... | Ray tracing; Volume visualization; Isosurfaces; Maximum-intensity projection; Traversal optimizations | 1999 |
