Yes, I see that, both conceptually and from the POV definition. But it's
the PATTERN that turns this one-dimensional "thing" into actual 3D
spatial colors, no? It seems to me that a "color_map without a pattern" is
like a race horse without legs... simply a concept. That is, for any real
usefulness, 3D pattern and color_map are inextricably interwoven (which is
how I usually think of them.) That being the case, in what axis or axes can
I expect to see the visual results of FREQUENCY at work on the color_map?
I guess that's my basic question AND conceptual difficulty. I suppose the
answer depends on the pattern specified(?)
SCALE, by contrast, seems to have a very straightforward, clear and
understandable effect on the color_map and pattern simultaneously.

Didn't mean to lead everyone down a wrong path.
In my use of SCALE, I'm simply substituting it for FREQUENCY (in the same
location in the code), without any extra <x,y,z> modifiers. Straight
scaling of all axes equally, in other words.
