int vertexhedge(<geometry>geometry, int vertex)
<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.
vertex
The linear vertex number in the geometry. 0
is the first vertex.
Returns
The number for the half-edge that has vertex
as source and the vertex following vertex
in the primitive of vertex
as destination.
Returns -1
if failed to find the corresponding vertex.
Examples ¶
int vtxhedge; // Get the hedge out of vertex vertex number 2. vtxhedge = vertexhedge("defgeo.bgeo", 2);
