  rtcSetGeometryUserData - sets the user-defined data pointer of the
    geometry

  #include <embree3/rtcore.h>

  void rtcSetGeometryUserData(RTCGeometry geometry, void* userPtr);

The rtcSetGeometryUserData function sets the user-defined data pointer (userPtr argument) for a geometry (geometry argument). This user data pointer is intended to be pointing to the application’s representation of the geometry, and is passed to various callback functions. The application can use this pointer inside the callback functions to access its geometry representation.

The rtcGetGeometryUserData function can be used to query an already set user data pointer of a geometry.

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