This filter is the king of texture creating filters. It is extremely
efficient but very complex. It uses a mathematical method named
Cellular Automata.

Starting filter
You can find this filter from the image menu through
Filters → Render → Pattern → CML Explorer

“CML Explorer” filter options(Hue)
Filter options are distributed among
Hue,Saturation,
Value, Advanced,
others and
Misc.ops tabs.
Some more options are available. They will be described in
following section.
Preview
This filter offers you a Preview where you can see the
result of your settings before they are applied to the
image.
New seed; Fix seed; Random seed
Open; Save
With these both command buttons you can save pattern
settings in a file, and to get them back later.
Hue tab
This filter works in the HSV color model. In this tab, you
can set options for Hue.
Function type
In this drop-down list, you can select the method that
will be used to treat the current layer. These methods
are:
Keep image's values: With this
option, image hue values will be kept.
Keep the first value: With this
option, starting color will be standard cyan.
Fill with k parameter,
k{x(1-x)}^p,
k{x(1-x)}^p stepped,
kx^p,
kx^p stepped,
k(1-x^p),
k(1-x^p) stepped: pattern look
will depend on k that you will
set later in options.
Delta function,
Delta function stepped: FIXME
sin^p based Function,
sin^p stepped: These options
create wave-like patterns, like aurora borealis or
curtain folds.
A book could be filled with results of all these
functions. Please, experiment!
Misc. Arrange
This drop-down list offers you some other parameters:
Standard,
Use average value,
Use reverse value,
With random power (0,10),
With random power (0,1),
with gradient power (0,1),
Multiply rand. value (0,1),
Multiply rand. value (0,2),
Multiply gradient (0,1) and
With p and random (0,1).
Also a book would be necessary to explain all
possibilities of these parameters.
Use cyclic range
//TODO
Mod. rate
With this slider and the input box, you can set
modification rate from 0.0 to 1.0. Low value results in a
lined pattern.
Env. sensitivity
Value is from 0.0 to 1.0
Diffusion dist.
Diffusion distance: from 2 to 10.
# of subranges
Number of sub-rangers: from 1 to 10.
(P)ower factor
With this option you can influence the
Function types using the
p parameter. Value from 0.0 to 10.0.
k Parameter
With this option you can influence the
Function types using the
k parameter. Value from 0.0 to 10.0.
Range low
Set lower limit of hue that will be used for calculation.
values vary from 0.0 to 1.0.
Range high
Set the upper limit of hue that will be used for
calculation. Variations are from 0.0 to 1.0.
Plot a graph of the settings
By clicking on this large button, you can open a window
that displays the graph of hue present settings.
In this tab you can find various options about copy and loading.
Copy settings
These options allow you to transfer information from
one of the HSV channel to another one.
Selective load setting
With the Open button of this
filter, you can load previously loaded settings. If you
don't want to load all of them, you can select a source
and a destination channel here.
