int hedge_presrcpoint(<geometry>geometry, int hedge)
<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 point of the point into which the vertex that comes before the source vertex of the hedge
in the primitive that contains hedge
is wired.
Returns -1
if the half-edge is not valid.
Examples ¶
int presrcpt; // Get the pre-source point of half-edge number 3. presrcpt = hedge_presrcpoint("defgeo.bgeo", 3);
