NAME rtcAttachGeometryByID − attaches a geometry to the scene   using a specified geometry ID

---

SYNOPSIS #include <embree3/rtcore.h> void rtcAttachGeometryByID(   RTCScene scene,   RTCGeometry geometry,   unsigned int geomID );

---

DESCRIPTIONThe rtcAttachGeometryByID function attaches a geometry (geometry argument) to a scene (scene argument) and assigns a user provided geometry ID (geomID argument) to that geometry. All geometries attached to a scene are defined to be included inside the scene. A geometry can get attached to multiple scenes. The passed user−defined geometry ID is used to identify the geometry when hit by a ray during ray queries. Using this function, it is possible to share the same IDs to refer to geometries inside the application and Embree. This function is thread−safe, thus multiple threads can attach geometries to a scene in parallel. The user−provided geometry ID must be unused in the scene, otherwise the creation of the geometry will fail. Further, the user−provided geometry IDs should be compact, as Embree internally creates a vector which size is equal to the largest geometry ID used. Creating very large geometry IDs for small scenes would thus cause a memory consumption and performance overhead.

---

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