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

rtcGetGeometryThreadSafe - returns the geometry bound to
  the specified geometry ID


#include <embree4/rtcore.h>
RTCGeometry rtcGetGeometryThreadSafe(RTCScene scene, unsigned int geomID);

The rtcGetGeometryThreadSafe function returns the geometry that is bound to the specified geometry ID (geomID argument) for the specified scene (scene argument). This function just looks up the handle and does not increment the reference count. If you want to get ownership of the handle, you need to additionally call rtcRetainGeometry.

This function is thread safe and should NOT get used during rendering. If you need a fast non-thread safe version during rendering please use the [rtcGetGeometry] function.

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