rtcGetGeometryUserDataFromScene(3) Embree Ray Tracing Kernels 4 rtcGetGeometryUserDataFromScene(3) 

rtcGetGeometryUserDataFromScene - returns the user data pointer
  of the geometry through the scene object


#include <embree4/rtcore.h>
void* rtcGetGeometryUserDataFromScene(RTCScene scene, unsigned int geomID);

The rtcGetGeometryUserDataFromScene function queries the user data pointer previously set with rtcSetGeometryUserData from the geometry with index geomID from the specified scene scene. When rtcSetGeometryUserData was not called yet, NULL is returned.

In contrast to the rtcGetGeometryUserData function, the rtcGetGeometryUserDataFromScene function an get used during rendering inside a SYCL kernel.

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