Calculates the UV coordinates of a spatial projection, and stores it as a per-polynode 3D vector attribute on the "self" object that can be used as a texture projection when rendering.
|   Attribute Name  | 
                    Specify the name of an attribute to store the 3D vector texture coordinates per polynode.  | 
               
|   Normalize  | 
                    Normalizes the XYZ components to the interval [0, 1].  |
