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

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


#include <embree4/rtcore.h>
void* rtcGetGeometryUserDataFromTraversable(
    RTCTraversable traversable,
    unsigned int geomID);

The rtcGetGeometryUserDataFromTraversable function is equivalent to rtcGetGeometryUserDataFromScene but takes traversable object (traversable argument) instead of a scene object. Using this method is optional on CPU but it is required for SYCL.

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