How to Setup the Script Arguments

The app’s Script Arguments popover is used to configure a script’s input arguments.

Open the popover, then select the Script Args tab.

Enter the input argument’s name plus its value into the table. (Click the + button to add a new row to the table first.)

Splicing Category

These scripts splice another fractal onto this one.

They all have a script input argument that specifies which main Lua script to use to create the other fractal.

Special Technique

Use “Save Fractal as Lua script” to create a new main Lua script from a fractal. This creates a Lua script that will always create that same fractal.

Otherwise, the other main scripts will always create random fractals. (This is Ok, but sometimes you might want to work with 1 specific other fractal.)

inlineConcat.lua

This tweak script splices (concatenates) another fractal onto this one. The other fractal is created by invoking a Make Random script, i.e. “simil3”.

This fractal is A and the other fractal is B.

For each transform, this is the output variation chain:

A.pre's, B.pre's,  A.variations, B.variations, A.post's, B.post's

Input Arguments:

See: How to Setup the Script Arguments

script: The name of a main Lua script that will create the other fractal.; Its default value: “simil3”.; For example, to use the script “simil4.lua”, set script to “simil4” using the Script Arguments popover in the app.

inlinePlusMatricesConcat.lua

This tweak script splices (concatenates) another fractal onto this one. This script includes the other fractal’s pre and post transforms as well (by splicing them in as a matrix variation group).

A.pre's, B.preMatrix, B.pre's,  A.variations, B.variations, A.post's, B.post's, B.postMatrix

Inserting Variations + Parameters (Varpars) Category

Some of the best Lua scripts randomly insert these into the original fractal at various places in each transform’s variation group chain.

The term varpars represents a list of variations + their parameter values.

Open the popover, then select the Setup Varpars tab.

Next, check the variation types you want and set their parameter input value ranges.
