Description

Algorithms for making interesting organic simulations is a long technical article by Etienne Jacob on bleuje.com. The URL is one guided write-up of Physarum-style agent simulations for artistic use, with interactive figures and GPU notes.

It explains Jeff Jones 2010 Physarum sensing, rotation, deposit, and trail diffusion, then Sage Jenson 36 Points ideas that make sensor and move parameters depend on local trail value, plus offsets and respawn. The author documents an openFrameworks compute-shader port with millions of particles, deposit and decay choices, delayed-trail coloring, inertia experiments, and cursor-based mixing of parameter Points. Code snippets and performance notes are included under a Creative Commons style license note.

The audience is intermediate creative coders and graphics programmers comfortable with GLSL-like GPU work. Artistic curiosity matters more than biology expertise.

The page is free HTML with embedded demos and links to repositories for the 36 Points-inspired and interactive projects.

It helps when building organic trail simulations and adapting 36 Points-style parameter fields without reverse-engineering from visuals alone.
