.SS DESCRIPTION
.PP
The \f[C]rtcFilterIntersection\f[R] function can be called inside an
\f[C]RTCIntersectFunctionN\f[R] callback function to invoke the
intersection filter registered to the geometry and stored inside the
context.
For this an \f[C]RTCFilterFunctionNArguments\f[R] structure must be
created (see \f[C]rtcSetGeometryIntersectFilterFunction\f[R]) which
basically consists of a valid mask, a hit packet to filter, the
corresponding ray packet, and the packet size.
After the invocation of \f[C]rtcFilterIntersection\f[R], only rays that
are still valid (valid mask set to \-1) should update a hit.
.SS EXIT STATUS
.PP
For performance reasons this function does not do any error checks, thus
will not set any error flags on failure.
