int hedge_next(<geometry>geometry, int hedge)
When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.
Alternatively, the argument can be a string specifying a geometry file (for example, a
.bgeo) to read from. When running inside Houdini, this can be an
The number of the half-edges that follow (its source is the destination of)
hedge in the polygon that contains it. Returns
-1 if the half-edge is not valid.
int nexthedge; // Get the next half-edge of half-edge number 3. nexthedge = hedge_next("defgeo.bgeo", 3);
