Main panel OSXLCAU21 window

The Main panel OSXLCAU21 window is the one which controls most of the actions of the system and provides useful information. The NSTextField object evolution rule allows to edit directly the evolution rule that we desire to visualize; the rule is introduced in decimal notation, taking values from 0 up to 255. The NSSlider object density allows to define the density of the configuration initial, a density close to zero means that state 0 will occupy most of the cells in the configuration initial, in the opposite case state 1 dominates. This density can be directly introduced in its NSTextField whether an exact density is desired.

For instance, Rule 110 finds its statistical stability approximately in 0.57, hence this value can be directly introduced in the initial density.

The object size cell allows to define different sizes in which the cells can be seen in the evolution space, the rank of the different sizes goes from 1 up to 10. This feature is useful when we desire a better visualization of both a particular collision or a given structure.

The object cells shows the number of cells in the configuration initial and the object gen presents the number of calculated generations, these values are updated whenever the user defines a new size in the window presenting the evolution.

The NSButton object configuration initial assigns a random initial configuration according to the density and the colors defined at this time. The button evolution calculates and shows the evolution from the currently defined initial configuration. The evolution is drawn in each line.

The button continue evolution calculates and shows the continuation of the previous evolution from the last generation of the first evolution. Each time we continue with the evolution, the number of generations is also updated in the NSTextField gen. The button clear view cleans the evolution space and initializes all the variables of the system. The button paint ether colors the T$_{3}$ mosaic in other colors defined by the user, this feature is useful to get a better visualization of single gliders or complex collisions between several gliders against the periodic background.

The NSMatrix objects space and no-space establish a small division between each one of the cells, this is useful when the user wants a detailed view of the number of cells involved in a given sequence or region.
