### 13.9. CML Explorer

#### 13.9.1. Overview

Afbeelding 17.299. Example for the “CML Explorer” filter

Filter “CML Explorer” applied with default options

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].

#### 13.9.2. Activating the filter

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

#### 13.9.3. Options

##### 13.9.3.1. General Options

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.

##### 13.9.3.2. “CML Explorer” filter options (Hue)

Afbeelding 17.300. 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 parameter k

    Pattern look will depend on `k` that you will set later in options.

  Miscellaneous f(k)

    See above, “Fill with k parameter”.

  Delta function, Delta function stepped

    // TODO

  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 choose among several functions, and a book could be filled with results of all these functions. Please, experiment!

Misc. arrange

  This drop-down list offers you several other parameters. 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.

Parameter k

  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.

##### 13.9.3.3. “CML Explorer” filter options (Saturation)

Afbeelding 17.302. Saturation tab

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.

##### 13.9.3.4. “CML Explorer” filter options (Value)

Afbeelding 17.303. Value tab

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.

##### 13.9.3.5. “CML Explorer” filter options (Advanced)

Afbeelding 17.304. Advanced tab

These tab settings apply to the three HSV channels.

Channel sensitivity

  // TODO

Mutation rate

  // TODO

Mutation distance

  // TODO

##### 13.9.3.6. “CML Explorer” filter options (Others)

Afbeelding 17.305. Others tab

In this tab, you can find various parameters about image display and random intervention.

Initial value

  // TODO

Zoom scale

  // TODO

Start offset

  // TODO

Seed of Random

  // TODO

##### 13.9.3.7. “CML Explorer” filter options (Misc Ops.)

Afbeelding 17.306. Miscellaneous options tab

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 Settings

  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.
