prim

<type> prim(<geometry>geometry, string attribute_name, int primnumber)

<type>[] prim(<geometry>geometry, string attribute_name, int primnumber)

<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.

attribute_name

The name of the attribute (or intrinsic) to read.

primnumber

The primitive number to read the attribute on.

Returns

The value of the given attribute on the given point number, or 0 if the attribute or point do not exist.
