NAME
SYNOPSIS
DESCRIPTIONThe rtcOccludedNM function checks whether there are any hits for a stream of M ray packets (ray argument) of size N with the scene (scene argument). The ray argument points to an array of ray packets with specified byte stride (byteStride argument) between the ray packets. See Section [rtcOccluded1] for a description of how to set up and trace occlusion rays.A ray in a ray stream is considered inactive if its tnear value is larger than its tfar value. The packet size N must be larger than 0, and the stream size M can be an arbitrary positive integer including 0. Each ray must be aligned to 16 bytes. EXIT STATUSFor performance reasons this function does not do any error checks, thus will not set any error flags on failure.SEE ALSO[rtcIntersectNM] Visit the GSP FreeBSD Man Page Interface. |
