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