rtcRetainGeometry - increments the geometry reference count
#include <embree3/rtcore.h> void rtcRetainGeometry(RTCGeometry geometry);
Geometry objects are reference counted. The rtcRetainGeometry function increments the reference count of the passed geometry object (geometry argument). This function together with rtcReleaseGeometry allows to use the internal reference counting in a C++ wrapper class to handle the ownership of the object.
On failure an error code is set that can be queried using rtcGetDeviceError.
