img-voronoi

Interactive Voronoi diagram visualization from images, with animated site physics and a Rust CLI for video rendering.

Live demo | Originally forked from txstc55/ImageVoronoi

Features

• Voronoi from images: brightness-weighted site sampling, CPU flood-fill and WebGL cone rendering
• WASM backend: Rust-compiled Voronoi compute with O-U physics (centroid pull, drift, wander)
• Animation: play/pause/step with configurable speed, doubling time for gradual site growth
• Image gallery: always-visible collapsible sidebar, OPFS storage with thumbnails, auto-seeds sample images on first visit, built-in Picsum photo browser
• Shareable URLs: all settings stored as URL hash params; src param loads any image by URL, embed param hides UI for clean embeds
• CLI video rendering: Rust CLI with phase specs (grow, hold, fade), ffmpeg encoding, GPU compute shader backend

Quick Start

pnpm install
pnpm dev        # http://localhost:8076

CLI

cd cli
cargo build --release
cargo run --release -- -i image.jpg -o output.mp4 -p n=400,dt=5 -p t=2 -p fade=3
