Overview
The start of a ‘falling sand’ shader using cellular automaton modeling.
As of yet:
- it doesnt’ have the sand fall to either direction when it stacks
- Uses a naive implementation to look at the 1000 pixels below the current cell to see if the whole stack is going to fall.
- Doesn’t stack well (layers form; I think this is due to some anti-aliasing, but I’m not 100% certain).
Controls
- Press
Cor the GUI button to clear the canvas - Click and drag to add new sand to the canvas
