graffito

A small stencil framework for quick design and visualization.

Requires Futhark and SDL2 and SDL2-ttf libraries with associated header files.

Building and running

First run futhark pkg sync once.

Then run make to build all programs.

The programs go in the bin directory:

• bin/template: A small template with comments in order to get started.
• bin/steal: An area-stealing algorithm, kind of.
• bin/routefinder: Visualize route finding.
• bin/gameoflifeprob: A probabilistic Game of Life.
• bin/gameoflife: A very basic, no-frills implementation of Game of Life.
• bin/closingframe: A growing black frame around a square of colors.
• bin/diamonds: Growing diamonds.
• bin/consistencyfier: Not sure yet.
• bin/lines: Scraggly lines.
• bin/producerconsumer: Glittering small movements.
• rain: Blue, long droplets.

Pass --help to any program to see which options can be changed.

Controls in the visualizations:

• Space: Pause
• S: Step once
• R: Reset

Adding stencils

• Create a new directory under stencils/ with a stencil.fut file and a Makefile.
• Extend the root Makefile.
