<h2>A solution</h2>
<p>In order to detect webgl compatibility and gracefully inform the user you can add <a href="https://github.com/mrdoob/three.js/blob/master/examples/js/Detector.js">https://github.com/mrdoob/three.js/blob/master/examples/js/Detector.js</a> to your javascript and use this example to avoid even attempting to render anything:</p>
<p>
Add [link:https://github.com/mrdoob/three.js/blob/master/examples/js/Detector.js]
to your javascript and run the following before attempting to render anything.
</p>
<pre><code>if (Detector.webgl) {
init();
animate();
} else {
var warning = Detector.getWebGLErrorMessage();
document.getElementById('container').appendChild(warning);
}
</code></pre>
<code>
if (Detector.webgl) {
init();
animate();
} else {
var warning = Detector.getWebGLErrorMessage();
document.getElementById('container').appendChild(warning);
}
</code>
