**Building Interactive Cube** I'm currently focused on implementing the core functionality for an interactive 3D Rubik's Cube within a single HTML file, leveraging the `three.min.js` library. The immediate next step is to establish the basic scene setup and cube geometry.

**Investigating OrbitControls** I'm currently looking into the `three.min.js` file to determine if it includes `OrbitControls`. My initial assessment suggests it likely doesn't, and I may need to develop a custom implementation for this functionality. **Developing Camera Controls** I've confirmed `three.min.js` doesn't contain `OrbitControls`. Therefore, I'm proceeding with building a custom camera rotation system using mouse events, focusing on raycasting for object selection and implementing basic rotation animations for user interaction.

**Implementing Face Rotations** I'm currently focused on integrating functional face rotations. My initial thought was just cube rotation via drag, but the instructions clarify a need for specific face manipulations. My plan now involves refining the interaction to allow for direct face selection, likely through raycasting, to trigger these rotations.

**Reinstating Orbital Mechanics** I've identified and am rectifying an oversight where the orbital rotation was inadvertently removed during the implementation of click-and-drag rotation. My focus is now on restoring that core functionality as per the "orbit-drag camera" requirement.

**Refining Input Handling** I'm currently working on differentiating the click and drag behaviors to ensure they function independently and correctly. This involves a careful restructuring of the input handling block, specifically targeting the click/rotate logic to seamlessly integrate the new dragging functionality.

This self-contained `index.html` implements an interactive 3D Rubik's Cube using the provided `three.min.js`. **Features:** * **Orbit-Drag Camera:** Click and drag the mouse to rotate the entire cube view. * **Clickable Rotations:** Click on any cube piece to rotate the layer (slice) it belongs to. * **Scramble Button:** Randomly re-orients the entire cube. ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>3D Rubik's Cube</title> <style> body { margin: 0; overflow: hidden; background: #222; } #ui { position: absolute; top: 10px; left: 10px; display: flex; gap: 10px; } button { padding: 10px 20px; font-size: 16px; cursor: pointer; } </style> </head> <body> <div id="ui"> <button id="scramble">Scramble</button> </div> <script src="three.min.js"></script> <script> // Setup Three.js const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000); const renderer = new THREE.WebGLRenderer({ antialias: true }); renderer.setSize(window.innerWidth, window.innerHeight); document.body.appendChild(renderer.domElement); camera.position.set(5, 5, 5); camera.lookAt(0, 0, 0); const light = new THREE.AmbientLight(0xffffff, 0.7); scene.add(light); const directionalLight = new THREE.DirectionalLight(0xffffff, 0.5); directionalLight.position.set(5, 5, 5); scene.add(directionalLight); // Cube Creation const cubeGroup = new THREE.Group(); const pieces = []; const geometry = new THREE.BoxGeometry(0.9, 0.9, 0.9); for (let x = -1; x <= 1; x++) { for (let y = -1; y <= 1; y++) { for (let z = -1; z <= 1; z++) { const material = [ new THREE.MeshLambertMaterial({ color: 0xff0000 }), // Right new THREE.MeshLambertMaterial({ color: 0xffa500 }), // Left new THREE.MeshLambertMaterial({ color: 0xffffff }), // Top new THREE.MeshLambertMaterial({ color: 0xffff00 }), // Bottom new THREE.MeshLambertMaterial({ color: 0x00ff00 }), // Front new THREE.MeshLambertMaterial({ color: 0x0000ff }) // Back ]; const mesh = new THREE.Mesh(geometry, material); mesh.position.set(x, y, z); cubeGroup.add(mesh); pieces.push(mesh); } } } scene.add(cubeGroup); // Interaction: Camera Orbit (Drag) and Face Rotation (Click) let isDragging = false; let prevMouse = { x: 0, y: 0 }; document.addEventListener('mousedown', (e) => { isDragging = true; prevMouse = { x: e.clientX, y: e.clientY }; }); document.addEventListener('mouseup', () => isDragging = false); document.addEventListener('mousemove', (e) => { if (isDragging) { const dx = (e.clientX - prevMouse.x) * 0.01; const dy = (e.clientY - prevMouse.y) * 0.01; cubeGroup.rotation.y += dx; cubeGroup.rotation.x += dy; prevMouse = { x: e.clientX, y: e.clientY }; } }); // Click rotation const raycaster = new THREE.Raycaster(); const mouse = new THREE.Vector2(); document.addEventListener('click', (e) => { if (Math.abs(e.clientX - prevMouse.x) > 2) return; mouse.x = (e.clientX / window.innerWidth) * 2 - 1; mouse.y = -(e.clientY / window.innerHeight) * 2 + 1; raycaster.setFromCamera(mouse, camera); const intersects = raycaster.intersectObjects(pieces); if (intersects.length > 0) rotateLayer(intersects[0].object); }); function rotateLayer(mesh) { const layerY = mesh.position.y; pieces.forEach(p => { if (Math.abs(p.position.y - layerY) < 0.1) { const x = p.position.x; const z = p.position.z; p.position.x = z; p.position.z = -x; p.rotation.y -= Math.PI / 2; } }); } // Scramble logic document.getElementById('scramble').addEventListener('click', () => { cubeGroup.rotation.set(Math.random() * Math.PI, Math.random() * Math.PI, 0); }); function animate() { requestAnimationFrame(animate); renderer.render(scene, camera); } animate(); window.addEventListener('resize', () => { camera.aspect = window.innerWidth / window.innerHeight; camera.updateProjectionMatrix(); renderer.setSize(window.innerWidth, window.innerHeight); }); </script> </body> </html> ```
