This is like osd_limitsurface but for vertex attributes instead of point attributes. See osd_limitsurface for more information.
int osd_limitsurfacevertex(<geometry>geometry, string attrib_name, int face_id, float u, float v, <type>&result)
int osd_limitsurfacevertex(<geometry>geometry, string attrib_name, int face_id, float u, float v, float &result[])
<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.
