Repairing Virtual Reality (VR) models is a challenge for productive applications. This paper describes a fast implementation of Nooruddin and Turk's ray-stabbing method 14 based on standard graphics hardware. Ray-stabbing is used to convert a polygonal model into a volume model (also called voxelization). The volume model is back-converted into a polygonal(More)
We study the effect of memory access ordering policies on processor performance. Relaxed ordering policies increase available instruction-level parallelism, but such policies must be evaluated subject to their effect on memory consistency — since virtually all microprocessors are designed to be compatible with shared memory multipro-cessor systems, even(More)
