This filter is the king of texture creating filters. It is extremely
efficient but very complex. It uses a mathematical method named Cellular
Automata [WKPD-CA].
13.7.2. Activating the filter
You can find this filter from the image menu through
→ → → .
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
-
Random plays a large part in creating patterns. With these
options, you can influence the way random is generated. By
clicking on the New seed button, you
can force random to use a new source of random. The preview
will show you the result.
Fix seed lets you keep the same seed
and so to reproduce the same effect with the filter.
Random seed generates a random seed
at random.
-
Open; Save
-
With these both command buttons you can save pattern
settings in a file, and to get them back later.
“CML Explorer” filter options(Hue)
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.
-
Composition
-
Here, these options concern Hue. You can select:
None, Max(x, -),
Max(x+d, -),
Max(x-d, -),
Min(x, -),
Min(x+d, -),
Min(x-d, -),
Max(x+d, -), (x < 0,5),
Max(x+d, -), (0,5 < x),
Max(x-d, -), (x < 0,5),
Max(x-d, -), (0,5 < x),
Min(x+d, -), (x < 0,5),
Min(x+d, -), (0,5 < x),
Min(x-d, -), (x < 0,5) and
Min(x-d, -), (0,5 < x).
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.
“CML Explorer” filter options(Saturation)
In this tab, you can set how Saturation component of the HSV
color model will be used in pattern calculation.
These options are similar to Hue tab options.
“CML Explorer” filter options (Value)
In this tab, you can set how the Value (Luminosity) component of
the HSV color model will be used in pattern calculation.
These options are similar to Hue tab options.
“CML Explorer” filter options (Advanced)
These tab settings apply to the three HSV channels.
-
Channel Sensitivity
-
// TODO
-
Mutation rate
-
// TODO
-
Mutation distance
-
//TODO
“CML Explorer” filter options (Others)
In this tab, you can find various parameters about image display
and random intervention.
-
Initial value
-
// TODO
-
Zoom factor
-
// TODO
-
Start offset
-
// TODO
-
Seed of random
-
// TODO
“CML Explorer” filter options (Misc.ops)
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.
