vertexhedge

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

examples

int vtxhedge;

// Get the hedge out of vertex vertex number 2.
vtxhedge = vertexhedge("defgeo.bgeo", 2);
