The \f[C]ray\f[R] argument points to an array of ray packets with specified byte stride (\f[C]byteStride\f[R] argument) between the ray packets. See Section [rtcOccluded1] for a description of how to set up and trace occlusion rays. .IP .nf \f[C] \f[R] .fi .IP .nf \f[C] \f[R] .fi .PP A ray in a ray stream is considered inactive if its \f[C]tnear\f[R] value is larger than its \f[C]tfar\f[R] value. .PP The packet size \f[C]N\f[R] must be larger than 0, and the stream size \f[C]M\f[R] can be an arbitrary positive integer including 0. Each ray must be aligned to 16 bytes. .SS EXIT STATUS .PP For performance reasons this function does not do any error checks, thus will not set any error flags on failure. .SS SEE ALSO .PP [rtcIntersectNM]
