pointattrib

<type> pointattrib(<geometry>geometry, string attribute_name, int pointnumber, int &success)

<type>[] pointattrib(<geometry>geometry, string attribute_name, int pointnumber, int &success)

<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.

&success

The function overwrites this variable with 1 if the attribute exists and was read successfully, or 0 otherwise.

Returns

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