#### Summary:
The goal of this tutorial is to give a brief introduction to simulate wind cloth by three.js. I will start by setting up a scene, camera, ligth, and renderer etc, so that I can render the wind cloth simulation.
#### Result:
#### What Will I Learn?
- html, css and javascript code structure
- how to refer to three.js and Cloth.js library
- how to create a Perspective Camera
- how to create scene
- how to create light
- how to create cloth
- how to create ground
- how to create poles
- how to create renderer
- how to create animation
#### Requirements
- source code editor, for example: vim, notepad++ etc.
- A browser that support webgl, for example: Google Chrome 9+, Firefox 4+, Opera 15+, Safari 5.1+, Internet Explorer 11 and Microsoft Edge etc.
#### Difficulty
- Intermediate
#### Tutorial Contents
- step 1: html, css and javascript code structure

```
- step 2: how to rerfer to three.js and Cloth.js library
```
<script src="js/three.min.js"></script>
<script src="js/Cloth.js"></script>
```
- step 3: how to create a Perspective Camera
```
camera = new THREE.PerspectiveCamera( 30, window.innerWidth / window.innerHeight, 1, 10000 );
camera.position.set( 0, 50, 1500 );
```
- step 4: how to create scene
```
scene = new THREE.Scene();
scene.background = new THREE.Color( 0xcce0ff );
scene.fog = new THREE.Fog( 0xcce0ff, 500, 10000 );
```
- step 5: how to create light
```
var light, materials;
var d = 300;
scene.add( new THREE.AmbientLight( 0x666666 ) );
light = new THREE.DirectionalLight( 0xdfebff, 1 );
light.position.set( 50, 200, 100 );
light.position.multiplyScalar( 1.3 );
light.castShadow = true;
light.shadow.mapSize.width = 1024;
light.shadow.mapSize.height = 1024;
light.shadow.camera.left = - d;
light.shadow.camera.right = d;
light.shadow.camera.top = d;
light.shadow.camera.bottom = - d;
light.shadow.camera.far = 1000;
scene.add( light );
```
- step 6: how to create cloth
```
// cloth material
var loader = new THREE.TextureLoader();
var clothTexture = loader.load( 'textures/patterns/circuit_pattern.png' );
clothTexture.anisotropy = 16;
var clothMaterial = new THREE.MeshLambertMaterial( {
map: clothTexture,
side: THREE.DoubleSide,
alphaTest: 0.5
} );
// cloth geometry
clothGeometry = new THREE.ParametricGeometry( clothFunction, cloth.w, cloth.h );
// cloth mesh
clothMesh = new THREE.Mesh( clothGeometry, clothMaterial );
clothMesh.position.set( 0, 0, 0 );
clothMesh.castShadow = true;
scene.add( clothMesh );
clothMesh.customDepthMaterial = new THREE.MeshDepthMaterial( {
depthPacking: THREE.RGBADepthPacking,
map: clothTexture,
alphaTest: 0.5
} );
```
- step 7: how to create ground
```
// ground
var groundTexture = loader.load( 'textures/terrain/grasslight-big.jpg' );
groundTexture.wrapS = groundTexture.wrapT = THREE.RepeatWrapping;
groundTexture.repeat.set( 25, 25 );
groundTexture.anisotropy = 16;
var groundMaterial = new THREE.MeshLambertMaterial( { map: groundTexture } );
var mesh = new THREE.Mesh( new THREE.PlaneBufferGeometry( 20000, 20000 ), groundMaterial );
mesh.position.y = - 250;
mesh.rotation.x = - Math.PI / 2;
mesh.receiveShadow = true;
scene.add( mesh );
```
- step 8: how to create poles
```
// poles
var poleGeo = new THREE.BoxBufferGeometry( 5, 375, 5 );
var poleMat = new THREE.MeshLambertMaterial();
var mesh = new THREE.Mesh( poleGeo, poleMat );
mesh.position.x = 125;
mesh.position.y = - 62;
mesh.receiveShadow = true;
mesh.castShadow = true;
scene.add( mesh );
var mesh = new THREE.Mesh( new THREE.BoxBufferGeometry( 255, 5, 5 ), poleMat );
mesh.position.y = - 250 + ( 750 / 2 );
mesh.position.x = 0;
mesh.receiveShadow = true;
mesh.castShadow = true;
scene.add( mesh );
var gg = new THREE.BoxBufferGeometry( 10, 10, 10 );
var mesh = new THREE.Mesh( gg, poleMat );
mesh.position.y = - 250;
mesh.position.x = 125;
mesh.receiveShadow = true;
mesh.castShadow = true;
scene.add( mesh );
```
- step 9: how to create renderer
```
// renderer
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
renderer.shadowMap.renderSingleSided = false;
container.appendChild( renderer.domElement );
renderer.gammaInput = true;
renderer.gammaOutput = true;
renderer.shadowMap.enabled = true;
```
- step 10: how to set animation
```
function animate() {
requestAnimationFrame( animate );
var time = Date.now();
var windStrength = Math.cos( time / 7000 ) * 20 + 40;
windForce.set( Math.sin( time / 2000 ), Math.cos( time / 3000 ), Math.sin( time / 1000 ) )
windForce.normalize()
windForce.multiplyScalar( windStrength );
simulate( time );
render();
}
function render() {
var p = cloth.particles;
for ( var i = 0, il = p.length; i < il; i ++ ) {
clothGeometry.vertices[ i ].copy( p[ i ].position );
}
clothGeometry.verticesNeedUpdate = true;
clothGeometry.computeFaceNormals();
clothGeometry.computeVertexNormals();
renderer.render( scene, camera );
}
