primvertexcount

int  primvertexcount(<geometry>geometry, int prim_num)

<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.

prim_num

The primitive number of the primitive to count vertices on.

Returns

The number of vertices in the given primitive, or -1 if the primitive does not exist.

Examples

examples

int        nvtx;

// Get the number of vertices of primitive 3
nvtx = primvertexcount("defgeo.bgeo", 3);
