Attached an image of four isosurfaces occupying the same bounded space. 
Using one polygon object, but with four different potential pattern 
settings wrapped in four functions for the isosurfaces.

I used a 'bounded_by' to create an overly large bounding box and, on 
rendering, the flag -ur so it wasn't ignored.

The white frame is what the 'ip_type 3' bounding frame looks like. (I 
had a bug in this code I didn't see just looking at it as a pigment on a 
plane. Now fixed.)

The yellow-brown shape is the 'ip_type 6' potential value field of the 
polygon itself.

The blue-grey rods the 'ip_type 4' spheres for polygon points scaled big 
in z so as to clip on the isosurfaces bounding box.

The yellow lines the 'ip_type 5' connected point to point value field 
scaled slightly larger in z so the smaller ip_offset protrudes enough to 
just show up.
