PHYSARUM
Grow living networks in your browser.
PHYSARUM simulates slime mold. Every agent senses the trail ahead, turns toward the strongest path and leaves its own, and hair-thin networks grow out of nothing and keep reorganizing for as long as you watch.
It runs in the browser on WebGPU at screen resolution and beyond, with up to 16 million agents. Zoom in and the strands keep their detail. A 3D mode grows the same networks in a volume you can orbit.
What it does
- Up to 16 million agents on a trail map at 4K and beyond, 60 fps on a modern GPU
- Hyphae, veins, cellular, spore bloom and three-species symbiosis presets
- Paint food or repellent, zoom into the fine detail, save full-resolution PNGs
- Every behavior and render setting live on sliders
- A 3D mode for volumetric growth
It runs in your browser.
