hedge_nextequiv

int  hedge_nextequiv(<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 next half-edge equivalent to hedge, or hedge if there are no other half-edges equivalent to it. Successive calls to hedge_nextequiv() cycle through all the equivalent half-edges. Returns -1 if the half-edge is not valid.

Examples

examples

// Determine the number of half-edges equivalent to half-edge number 3 (including itself)
int num_equiv = 0;
int h = 3;
do
{
h = hedge_nextequiv("defgeo.bgeo", h);
num_equiv++;
} while (h != 3);
