.SS SYNOPSIS
.IP
.nf
\f[C]
#include <embree3/rtcore.h>

void rtcFilterOcclusion(
  const struct RTCOccludedFunctionNArguments* args,
  const struct RTCFilterFunctionNArguments* filterArgs

.SS DESCRIPTION
.PP
The \f[C]rtcFilterOcclusion\f[R] function can be called inside an
\f[C]RTCOccludedFunctionN\f[R] callback function to invoke the occlusion
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]rtcFilterOcclusion\f[R] only rays that are
still valid (valid mask set to \-1) should signal an occlusion.
.SS EXIT STATUS
.PP
For performance reasons this function does not do any error checks, thus
will not set any error flags on failure.
