Cosmic Web Structure Simulator (2D)

2D Canvas cosmic-web simulation: node seeds spawn a nearest-neighbour filament skeleton, then thousands of galaxies interpolate from a uniform scatter into nodes, filaments and voids in real time.

This 2D companion drives the same procedural node-and-filament model as the 3D version: random node seeds are threaded into a filament skeleton by nearest-neighbour pairing, and thousands of galaxies interpolate from a uniform scatter onto a node, a filament, or the sparse background, revealing the web-like structure as it settles.

⚙ Under the hood

Canvas2D port of the cosmic-web node/filament model: adjustable galaxy count, filament clustering and void size, with click-to-plant seed interaction and live settling-progress readouts.
