DiceLab — Dice Physics

Roll real physics dice — and watch how two different engines disagree about what "real" means. DiceLab is a 3D dice roller built as an open study in Apple physics: the same dice, the same table — simulated by SceneKit or by RealityKit, your pick. Switch engines in Settings and feel the difference in weight, bounce, and settling. • One to six dice, d6 or d20, on a felt table — tap Roll and let the physics decide. • Two engines, honestly different — SceneKit and RealityKit don't simulate alike; DiceLab keeps them side by side so you can see it. • Pace × viscosity — separate the speed of the simulation from the drag on the dice, and find the feel that reads "right" to you. • Make the table yours — recolour the felt or lay your own photo on it, pick a backdrop, turn the cloth into a mirror, and tune light and materials live. • Roll history — recent totals one tap away. Everything is on-device: no accounts, no ads, no tracking, no network calls.
