检测使用 three.js 时的 WebGL 和浏览器兼容性
（Detecting WebGL and browser compatibility with three.js）

遇到的问题
The problem

Not all browsers support WebGL, in fact only chrome and firefox work with three.js WebGLRenderer currently. iOS works with the canvas renderer and although IE9 supports canvas, it doesn't support workers so currently isn't supported.

一种解决方案
A solution

In order to detect webgl compatibility and gracefully inform the user you can addhttps://github.com/mrdoob/three.js/blob/master/examples/js/Detector.js to your javascript and use this example to avoid even attempting to render anything:

if (Detector.webgl) {
    init();
    animate();
} else {
    var warning = Detector.getWebGLErrorMessage();
    document.getElementById('container').appendChild(warning);
}
