Capabilities

Everything you need to simulate

A complete toolkit for building interactive physics scenes, from rigid bodies to cloth to custom scripting.

Rigid Body Physics

Drop cubes and spheres into a real-time physics world with adjustable mass, friction, and restitution.

Cloth Simulation

Verlet-integrated cloth with configurable stiffness, wind, and pin points. Drape it over objects in real time.

Physics Scripting

Write JavaScript that runs every physics frame. Apply forces, torques, and impulses to any object in the scene.

Visual Scene Editor

Select, translate, and rotate objects with gizmo controls. Adjust properties in a clean inspector panel.

One-Link Sharing

Generate a unique URL for any scene. Anyone with the link can open and explore your simulation instantly.

Custom Mesh Code

Define procedural geometry with code. Import custom shapes and add them to the physics world.
