primpoint

int  primpoint(<geometry>geometry, int primnum, 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.

primnum

The primitive number to get a vertex from.

vertex

The vertex number inside of a primitive. 0 is the first vertex.

Returns

The point number the vertex is wired to. Returns -1 if failed to find the corresponding point.
