What this is
Vein growth uses space colonisation, a way leaves and roots are modelled: scattered points pull the nearest branch tip toward them and vanish once reached. Brighter and edge areas of the picture get more points, so the veins follow its shapes.
How to use it
- Tap the image to grow veins from that point.
- Choose where they sprout, then set density, taper and glow with the sliders.
- Swap in your own two images, then save a PNG or record a video.

Common questions
Where do my pictures go?
Nowhere. They are opened in your browser and drawn on your graphics card. Nothing is uploaded. The pictures you add stay on this device, in this browser, so the other lab tools can open them too; × on a picture removes it.
