Comparing LinSyS and NomadS:

NomadS:

Is a compendium of individual works which can be categorized as follows:

----------- Free movement ---------------

VarBoxXY        -Automous box (changing size, colour and position) with feelpoints at corners

VarLinXY         -Autonomous line with feelpoints at ends

MadProc         -Autonomous block with colour and position movement dependent on pixel values at location

ColMadProc    -As MadProc but with limited colour change

VarLinProc      -As  MadProc but with variable line instead of block

----------- Line swap ---------------

VarWalkProc     -Similar to  VarlinProc, but with position moved to end of previous line

SwapWalkProc  -As VarWalkProc, but with line rotation values all shifted by a half circle


----------- Mirrored ---------------


MirWingProc   -As VarlinProc, but composed of two figures, with second figure mirroring the first

IndWingProc   -As VarlinProc, but composed of two figures, with second figure independent of first
                


----------- FigProc ---------------

FigProc       -Independent nomad -but with concentric polygons, instead of lines.

This is available in two options -with either a small or a large step between figures.

Analysis:

The basic element is a line segment, that can change position, colour,  angle and radius.

Colour, angle and radius are all free and independent, but location may sometimes (in the Line Swap category)
be rigidly determined by the nature of the process used.

Mirroring is not advisable as an option in all cases (particularly the in the Line Swap category)

The line segment could be interpreted as a "glyph" (a visual element)  -which allows other glyphs to represent the same data.

-Main Question: What to change, when to change and how to change:

LinSyS:

Various systems of movement based on:

-angle of line segment (rotation)
-length of line segment (radius)
-position of line segment (X,Y coordinates)
-visual representation of line segment

Note: Modification of limits of values is implemented for X,Y coordinates but not other paramenters

The "Box" feature in NomadS has become a "meta-space" which makes the "image area" variable. ("line" has been dropped -because it seemed to have no relevant equivalent in the new system).

FigProc was originally considered to be a separate process (like the Line Swap category) but as development continued it became clear that it was simply a complex "glyph". This means that one is free to use all other systems of movement, rotation, colour processing, etc. (including mirroring) before selecting the glyph. Obviously, this inreases the range of available options.

The chosen parameters of the final system are clearly reflected in the menu structure see Notes on LinSyS
