  • Parallel Performance Measures for Volume Ray Casting VGC

    Abstract. We describe a technique for achieving fast volume ray casting on parallel machines, using a load balanc ing scheme and an e cient pipelined approach to com positing. We propose a new model for measuring the amount of work one needs to perform in order to ren der a given volume, and use this model to
