threejs中的渐变clearColor

gradient clearColor in threejs

我可以在threejs中获得纯色clearColor,但是有没有办法实现渐变clearColor。或者一些类似的方法来在我的天空中获得更多的深度,也许用灯光?

这是我的相关代码:

renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setClearColor( 0x3dc800 );

var light = new THREE.HemisphereLight( 0xffffff, 0xeeeeee, 0.75 );
  light.position.set( 0.5, 1, 0.75 );
  scene.add( light );

scene.fog = new THREE.Fog( 0x4ff904, 0, 750 );

参见Transparent background with three.js for transparent background rendering and then you can apply CSS gradients http://www.w3schools.com/Css/css3_gradients.asp,但它不会随着您的场景移动,除非您真的很棘手。

我 运行 穿​​过这个代码笔:

我不相信,但它完美地回答了这个问题。

相关的块是:

renderer = new THREE.CanvasRenderer( { alpha: true }); // gradient

与 css:

body {
            background-color: #1A8FCF;
            margin: 0px;
            overflow: hidden;
            background-image: -webkit-gradient(#1A8FCF,#D1236A,#1A8FCF);
            /* Safari 5.1, iOS 5.0-6.1, Chrome 10-25, Android 4.0-4.3 */
            background-image: -webkit-linear-gradient(#1A8FCF,#D1236A,#1A8FCF);
            /* Firefox 3.6 - 15 */
            background-image: -moz-linear-gradient(#1A8FCF,#D1236A,#1A8FCF);
            /* Opera 11.1 - 12 */
            background-image: -o-linear-gradient(#1A8FCF,#D1236A,#1A8FCF);
            /* Opera 15+, Chrome 25+, IE 10+, Firefox 16+, Safari 6.1+, iOS 7+, Android 4.4+ */
            background-image: linear-gradient(#1A8FCF,#D1236A,#1A8FCF);
        }

**注意,我自己的颜色...
