If I have a face primitive, how do I find the faces which share an edge with the face? I don't seem to be able to find a function in GEO_HedgeInterface which will do this.
And GU_Detail::buildRingZeroPrimitives appears to return all faces which share a point with the face in question, which is not what I need.
In VEX, I've done this in a attribute wrangle which runs over primitives by calling primhedge(), which gives me a half-edge in the face, which I can then use to circulate around the face and query for edge neighbours.
Any help immensely appreciated!
