While thinking of deleting the quilted value pattern, started to toy
with the idea of replacing it with a seed pattern having values in the
function_interval range of -1 to 1.
The wave shape modifiers have been extended to support +- function
values, but to make use of them without some seed, you need to create
functions as input.
What if we had one or more seed or base patterns aimed at being fuel for
more complex patterns?
Idea thus far looks promising.Two images attached. One showing the
concept from seed pattern through to more complex patterns derived from
it. The other a larger fall color image using the technique.
A - The seed pattern on a y plane. Negative values as red and positive
values as green. The black between the near 0 values.(using
B - What is in A, but used directly in an isosurface.
C - Combining two of A in an average pigment. (function_interval)
D - Pattern of C as an isosurface.
E - C pattern (adding sine_wave along with function_interval)
F - Using E in an isosurface.
G - Adding six more rotations of A to the C average pigment.
H - G using the modified povr cubic_wave (selection) functionality.
I - H adding phase -0.1 to shift the colors toward negative red.
J - H again with phase +0.1 and adding some turbulence.
K - J adding the povr wave inverse wave keyword.
L - J made more turbulent. Adding a light to the scene.
