Basics

Basic animation example

// Canvas
const canvas = document.querySelector('canvas.webgl')

// Scene
const scene = new THREE.Scene()

// Object
const geometry = new THREE.BoxGeometry(1, 1, 1)
const material = new THREE.MeshBasicMaterial({ 
    color: 0xff0000 
})
const mesh = new THREE.Mesh(geometry, material)
scene.add(mesh)

// Sizes
const sizes = {
    width: 800,
    height: 600
}

// Camera
const camera = new THREE.PerspectiveCamera(75, sizes.width / sizes.height)
camera.position.z = 3
scene.add(camera)

// Renderer
const renderer = new THREE.WebGLRenderer({
    canvas: canvas
})
renderer.setSize(sizes.width, sizes.height)

// ANIMATIONS
const clock = new THREE.Clock()

const tick = () =>
{
    const elapsedTime = clock.getElapsedTime()
    //console.log(elapsedTime)
    
    // rotate the cube
    mesh.rotation.y = elapsedTime * Math.PI * 0.1

    // circular movement of camera
    camera.position.y = Math.sin(elapsedTime)
    camera.position.x = Math.cos(elapsedTime)
    camera.lookAt(mesh.position)
    
    // Render new setting
    renderer.render(scene, camera)
    
    // tell JS to call tick on the next frame
    window.requestAnimationFrame(tick) 
}

// GO...
tick()
