int hedge_prev(<geometry>geometry, int hedge)
Returns -1
if hedge
is invalid. Otherwise, returns the number of the half-edge
that precedes (its destination is the source of) hedge
in the polygon that contains it.
<geometry>
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 op:/path/to/sop
reference.
hedge
Input half-edge.
Returns
The number of the half-edge that precedes (its destination is the source of) hedge
in the polygon that contains it.
Returns -1
if the half-edge is not valid.
Examples ¶
int prev; // Get the previous half-edge of half-edge number 3. prevhedge = hedge_prev("defgeo.bgeo", 3);
