NAME rtcSetGeometryMask − sets the geometry mask

---

SYNOPSIS #include <embree3/rtcore.h> void rtcSetGeometryMask(   RTCGeometry geometry,   unsigned int mask );

---

DESCRIPTIONThe 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. Ray masks are disabled in Embree by default at compile time, and can be enabled through the EMBREE_RAY_MASK parameter in CMake. One can query whether ray masks are enabled by querying the RTC_DEVICE_PROPERTY_RAY_MASK_SUPPORTED device property using rtcGetDeviceProperty.

---

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