int hedge_isvalid(<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
The integer representing a half-edge.
Returns
1
if hedge
represents a valid half-edge in the referenced geometry, or 0
otherwise.
Examples ¶
int srcpt; // find the source point of a half-edge number 3 if it is valid if (hedge_isvalid("defgeo.bgeo", 3)) srcpt = hedge_srcpoint("defgeo.bgeo", 3);
