vertexpoint

int  vertexpoint(<geometry>geometry, int linearvertex)

<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.

linearvertex

The linear vertex number. The vertexindex function can be used to compute a linear vertex from a primitive number and vertex number pair.

Returns

The point number associated with the vertex, or -1 if the vertex has no point.

Examples

int        pt;

// Get the point of vertex 3
pt = vertexpoint("defgeo.bgeo", 3);
