#Quad

#Installation

Depends on the sdl2-dev package.

Build with make, run with ./quad.

The default size is 1024 pixels, optimized for 1080x1920px screens. To use another size (ideally a power of two or a number 2^n * m where m is small) run e.g ./quad 512 or ./quad 2048.

Run with make run.

#Interface

1. There are 8 rules
2. Rule 1 (top left) is expended to the image on the right
3. Rules are referenced by a small squares indicating their position in the editor interface
4. Each rule has one slot for each quadrant of the image
5. Each rule has a fallback slot that's used when a square gets too small to be subdivided further
6. Slots can contain patterns or references to rules, the fallback slot can only contain a pattern
7. To place a pattern in a slot, click it in the pallette at the top, then click on the slot
8. To place a reference to a rule in a slot, click on the small square next to it (the larger square region below also works), then click on the slot
