   NAME

              rtcSetGeometryMask - sets the geometry mask


   SYNOPSIS

              #include <embree4/rtcore.h>

              void rtcSetGeometryMask(
                RTCGeometry geometry,
                unsigned int mask
              );


   DESCRIPTION
       The rtcSetGeometryMask function sets a 32-bit geometry mask (mask
       argument) for the specified geometry (geometry argument).

       This geometry mask is used together with the ray mask stored inside the
       mask field of the ray.  The primitives of the geometry are hit by the
       ray only if the bitwise and operation of the geometry mask with the ray
       mask is not 0.  This feature can be used to disable selected geometries
       for specifically tagged rays, e.g. to disable shadow casting for
       certain geometries.

   EXIT STATUS
       On failure an error code is set that can be queried using
       rtcGetDeviceError.
