Latest commit bc48aed Oct 21, 2016 @zhanghaowx zhanghaowx committed with Update SkyShader.js to fix random dark sky due to float precision (#9888

* Previously if you put sun at vec3(0.0, 1.0, 0.0) and move it along the Y axis, the sky will suddenly become super dark at some random position. Further investigation shows the value passed into function sunIntensity is slightly larger than 1.0 due to float precision issue. Add a clamp will help get rid of such problems.


JavaScript 3D library

The aim of the project is to create an easy to use, lightweight, 3D library. The library provides <canvas>, <svg>, CSS3D and WebGL renderers.



Download the minified library and include it in your html. Alternatively see how to build the library yourself.

<script src="js/three.min.js"></script>

This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a WebGL renderer for the scene and camera, and it adds that viewport to the document.body element. Finally it animates the cube within the scene for the camera.

var scene, camera, renderer;
var geometry, material, mesh;


function init() {

    scene = new THREE.Scene();

    camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 10000 );
    camera.position.z = 1000;

    geometry = new THREE.BoxGeometry( 200, 200, 200 );
    material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true } );

    mesh = new THREE.Mesh( geometry, material );
    scene.add( mesh );

    renderer = new THREE.WebGLRenderer();
    renderer.setSize( window.innerWidth, window.innerHeight );

    document.body.appendChild( renderer.domElement );


function animate() {

    requestAnimationFrame( animate );

    mesh.rotation.x += 0.01;
    mesh.rotation.y += 0.02;

    renderer.render( scene, camera );


If everything went well you should see this.
