.SS SYNOPSIS

.nf
\f[C]
#include <embree4/rtcore.h>

void rtcInvokeOccludedFilterFromGeometry(
  const struct RTCOccludedFunctionNArguments* args,
  const struct RTCFilterFunctionNArguments* filterArgs
);

.SS DESCRIPTION
.PP
The \f[C]rtcInvokeOccludedFilterFromGeometry\f[R] function can be called
inside an \f[C]RTCOccludedFunctionN\f[R] user geometry callback function
to invoke the occlusion filter registered to the geometry.
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]rtcInvokeOccludedFilterFromGeometry\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.
