.SS DESCRIPTION
.PP
The \f[C]rtcIntersectNM\f[] function finds the closest hits for a stream
of \f[C]M\f[] ray packets (\f[C]rayhit\f[] argument) of size \f[C]N\f[]
with the scene (\f[C]scene\f[] argument).
The \f[C]rays\f[] argument points to an array of ray and hit packets
with specified byte stride (\f[C]byteStride\f[] argument) between the
ray/hit packets.
See Section [rtcIntersect1] for a description of how to set up and trace
rays.

.PP
A ray in a ray stream is considered inactive if its \f[C]tnear\f[] value
is larger than its \f[C]tfar\f[] value.
.PP
The packet size \f[C]N\f[] must be larger than 0, and the stream size
\f[C]M\f[] 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.
