Build 2D physics scenes for web pages with Matter.js. This skill guides engine setup, canvas rendering, adding objects, optional mouse dragging and connections between objects, plus cleanup when a scene is removed.
Use when implementing 2D physics interactions with Matter.js, including Engine/World setup, Render/Runner configuration, adding bodies and constraints, and scroll/interaction-friendly canvas scenes.
Review the instructions the agent will receive before you install.
<script>
const { Engine, Render, Runner, Bodies, Composite } = Matter;
const engine = Engine.create();
const render = Render.create({
element: document.body,
engine: engine,
options: {
width: 800,
height: 600,
wireframes: false
}
});
const runner = Runner.create();
Runner.run(runner, engine);
Render.run(render);
const ground = Bodies.rectangle(400, 610, 810, 60, { isStatic: true });
const box = Bodies.rectangle(400, 200, 80, 80);
Composite.add(engine.world, [ground, box]);
</script>
Composite.add(engine.world, [...]) to add bodies to the world.Render.create({ element, engine }) to create a canvas automatically, or pass a canvas you create yourself.render.options.wireframes = false for solid rendering.Runner.run(runner, engine) for a simple loop, or call Engine.update in your own loop if you need custom timing.const { Mouse, MouseConstraint } = Matter;
const mouse = Mouse.create(render.canvas);
const mouseConstraint = MouseConstraint.create(engine, { mouse });
Composite.add(engine.world, mouseConstraint);
render.mouse = mouse;

Build woven fabric in Three.js with visible threads, realistic sheen, seams, and thick hems. The skill covers folds that preserve texture proportions, light passing through thin cloth, and variations in dye and wear.
Build falling leaves in Three.js and similar 3D scenes, with visible front, edge, and back views as they tumble and drift. Coordinate wind, scene depth, camera-aware recycling, and performance checks for a convincing autumn effect.
Add coordinated seasonal transitions to an existing 3D scene. Blend foliage, lighting, sky, ground, snow, and particles from one shared state while preserving camera controls and interactions, so the same place remains recognizable throughout spring, summer, fall, and winter.
Create or integrate detailed 3D models with smooth outlines and believable edges for close-up views. Prepare lower-detail versions for distant viewing, prioritize loading, and measure rendering costs in the actual scene.
Prepare detailed 3D materials that remain clear in close-up views. The skill guides texture resolution, physically based material maps, surface mapping, filtering, and progressive loading while checking download size and GPU memory use.
Create realistic metal surfaces in Three.js by combining structured reflections, studio lighting, scratches, fingerprints, and beveled edges. Includes polished, brushed, and aged finishes for objects such as tools, rings, and metal product parts.
