If you want infinite thickness with an object pattern, you can wrap the
pattern in a function after having centerer the object with thickness
about some plane in space. Say the x-y plane at z=0. Then call your
FnWrapObjectPattern as FnWrapObjectPattern(x,y,0.0) making the pattern
effectively a 2D, infinite in z, x,y pattern.
