pointvertex

int  pointvertex(<geometry>geometry, int point_num)

Use this to find linear vertex number of the first vertex to share this point. Then you can use vertexnext to iterate over the other vertices in the point.

<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.

Returns

Returns the linear vertex number of the first vertex to share this point. Returns -1if no vertices share this point.

Examples

examples

int        vtx;

// Get the linear vertex  of point 3
vtx = pointvertex("defgeo.bgeo", 3);
