Paths that share the way

Many sources, set more in the dark areas, each find the cheapest route to a few hubs, set on the bright spots. Where routes share a stretch, the line gets thicker, so the picture ends up carrying a tree of branches, the way a river system or a bolt of lightning does. Edge Follow makes the edges of the picture the cheap way through, so the branches trace what is in the image.

Four ways to draw it

Ink on paper draws the branches on a plain ground. On image lays them over the picture. Image in lines fills the branches with the picture itself. Chrome turns them into glossy round tubes that reflect a studio and a softened copy of the picture. Thorns can add sharp spikes along the stronger branches.

Every option, from the app

Generated from the registry the app publishes, so this list is whatever the current build actually ships — not a copy of it.

  • Organic GrowthDendritic coral and frost branching outward from the image's own structure.
  • Reaction–DiffusionA Gray–Scott reaction–diffusion simulation seeded by your image, with curated feed/kill presets for spots, stripes, worms, mitosis, coral and chaos.
  • MetaballDepth points scattered into a volumetric density field and raymarched as an isosurface — blobs that genuinely fuse where they meet, with capsule connectors, cast shadows and ambient occlusion.
