Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Three.js Interaction ## When to Use - You need user interaction inside a Three.js scene. - The task involves raycasting, object picking, pointer handling, touch input, or camera controls. - You are building an interactive 3D experience rather than a passive render. ## Quick Start ```javascript import * as THREE from "three"; import { OrbitControls } from "three/addons/controls/OrbitControls.js"; // Camera controls const controls = new OrbitControls(camera, renderer.domElement); controls.enableDamping = true; // Raycasting for click detection const raycaster = new THREE.Raycaster(); const mouse = new THREE.Vector2(); function onClick(event) { mouse.x = (event.clientX / window.innerWidth) * 2 - 1; mouse.y = -(event.clientY / window.innerHeight) * 2 + 1; raycaster.setFromCamera(mouse, camera); const intersects = raycaster.intersectObjects(scene.children); if (intersects.length > 0) { console.log("Clicked:", intersects[0].object); } } window.addEventListener("click", onClick); ``` ## Raycaster ### Basic Raycasting ```javascript const raycaster = new THREE.Raycaster(); // From camera (mouse picking) raycaster.setFromCamera(mousePosition, camera); // From any origin and direction rayca

How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill threejs-interaction --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
