🧬 Eden Model vs. DLA Fractal Growth

Interactive 3D particle-growth simulator where switching between Eden model compact growth and diffusion-limited aggregation branching growth shows structures forming particle by particle.

A voxel cluster grows one particle at a time on a lattice — switch between the Eden model's compact, blob-like growth and diffusion-limited aggregation's sparse, branching growth to see how a single rule for "where does the next particle attach?" produces two completely different shapes.

🔬 What It Demonstrates

Eden growth fills every frontier cell with equal probability, staying compact with a fractal dimension near 2. DLA growth lets particles random-walk in from a distance, so branch tips shadow inner gaps and growth runs away at the tips, producing a sparser fractal with dimension near 1.7.

🎮 How to Use

Pick a growth model and lattice connectivity, then watch the cluster grow live. Tune growth speed to speed up or slow the process, and adjust DLA stickiness to see denser or lacier branches. Drag to orbit, scroll to zoom, and reset any time.

💡 Did You Know?

Witten and Sander's 1981 DLA paper explains an astonishing range of natural branching patterns — from mineral dendrites and electrical discharge figures to coral skeletons and some bacterial colonies — all from one simple random-walk sticking rule.
