25 Compiled tree

25 components are unique in that they act in many ways like a composite function that combines two functions with independent outputs (a space transform and a color texture generator) in one tile. When the input is a 2D space, the left two outputs are a space transform and the right three outputs are an RGB output texture. In many cases, you will use only the left two outputs or the rightmost outputs. When a 25 component is the bottom component of a tree its three right outputs are used for RGB output and the left two outputs are ignored.

Compiled Trees are groups of tiles that can be used in place of single tiles as a kind of macro or subroutine.

25 CT can hold any 2 input / 5 ouputs tree.

Select a 25 tile and use "**New compiled tree**" to create a new CT from the selection (**Tree Edit** menu or type 'n' key).

To save a CT on disk to use the function elsewhere use "**Save compiled tree**" from the **Tree Edit** menu.

You may also copy and paste the entire CT by using **Copy Tile** and **Paste Tile** from the **Edit** menu.

You may iterate the tree by "Iterations" number when the tree contains an Iterations tile to modify and accumulates various values. "Scale" provide an optionnal scaling of outputs and is set at 1 by default (no scaling).
