Features No Other Tool Offers
Built from real developer needs. Every feature below fills a gap that existing 3D tools leave wide open.
GPGPU Fluid & Particle Shaders
Curl noise flow fields, fluid surfaces, fire simulations —built-in shader presets no other visual tool offers.
Real-Time Performance Benchmarks
FPS, frame time, draw calls, and triangle counts with live graphs. Export benchmark data to JSON. No competitor does this.
Guided Tutorial System
Interactive step-by-step onboarding walks you through the entire simulator. Master 3D physics without a manual.
Physics + Shaders + Scripting
The only browser tool combining real-time rigid body physics, cloth simulation, GLSL shaders, and JavaScript scripting in one editor.
Preset Libraries for Every Level
Beginner-friendly scene presets and advanced showcase simulations. Start exploring in seconds, not hours.
One-Link Scene Sharing
Save your simulation to the cloud and share a single URL. Anyone can open, view, and interact with your scene instantly.
Physics, Cloth, and Shader Editing in the Browser
From rigid body simulations to custom GLSL shaders and procedural geometry —see what you can build without installing anything.
Physics that feels alive
Watch objects collide, bounce, and tumble with accurate rigid body dynamics. Adjust mass, friction, and restitution on the fly to see instant results.
Open Playground
Materials with soul
Write GLSL shaders that bring your materials to life. From iridescent surfaces to animated distortions, the shader editor gives you full creative control.
Open Playground
Geometry from code
Define geometry with code. Build parametric shapes, import custom models, and drop them straight into the physics world for instant simulation.
Open PlaygroundA Complete Browser-Based Simulation Toolkit
Rigid body dynamics, cloth simulation, JavaScript physics scripting, procedural mesh generation, and one-click sharing —all in one editor.
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.
Start Simulating in Seconds — No Install Required
