6              rtcGetGeometryFace - returns the face of some half edge

8   SYNOPSIS
9              #include <embree3/rtcore.h>
10
11              unsigned int rtcGetGeometryFace(
12                RTCGeometry geometry,
13                unsigned int edgeID
14              );

16   DESCRIPTION
17       The  rtcGetGeometryFace  function returns the ID of the face the speci‐
18       fied half edge (edgeID argument) belongs to.  For instance in the  fol‐
19       lowing example the face f1 is returned for edges e4, e5, e6, and e7.
20
21       This  function  can  only  be  used for subdivision geometries.  As all
22       topologies of a subdivision geometry share the  same  face  buffer  the
23       function does not depend on the topology ID.

25   EXIT STATUS
26       On  failure  an  error  code is set that can be queried using rtcGetDe‐
27       viceError.
