For multiplication of functions, I readily agree. It's the addition of functions
that has me puzzled. Strangely, I have never given much thought to the order of
them until now.
My present code is *so* complex-- for both the isosurface and matching texture
(pigment) functions-- that I cannot easily discern how the functions interact
visually, or if the order of them really matters.
I guess I should set up a much-simplified test with maybe two functions, and
switch them around to see...perhaps using a box function as the main object,
then sin(...) and f_noise3d for A and B. Or some other simple yet clearly
'different' pair of distortions. I'm still not entirely sure of what to expect,
or if I could even understand the visual difference when switching the two. It
is an interesting experiment to try, but difficult to pre-visualize the outcome.
I suppose that if there is *any* change at all, then the order does matter.
