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);
}

本文介绍了一种检测浏览器是否支持WebGL的方法,并提供了一个示例代码来优雅地通知用户当前浏览器是否兼容three.js的WebGL渲染器。目前仅Chrome和Firefox支持three.js的WebGL渲染。
