NAME
-
rtcGetGeometryFace - returns the face of some half edge
SYNOPSIS
-
#include <embree3/rtcore.h> unsigned int rtcGetGeometryFace( RTCGeometry geometry, unsigned int edgeID );
DESCRIPTION
The rtcGetGeometryFace function returns the ID of the face the specified half edge (edgeID argument) belongs to. For instance in the following example the face f1 is returned for edges e4, e5, e6, and e7.This function can only be used for subdivision geometries. As all topologies of a subdivision geometry share the same face buffer the function does not depend on the topology ID.
EXIT STATUS
On failure an error code is set that can be queried using rtcGetDeviceError.SEE ALSO
