I'm surprised that Firefox Mobile supports WebGL (and pretty quickly too). Neither Chrome nor Safari do.

At least Chrome Beta does, but iirc you need to enable it in about:flags.

It's weird more browsers don't, considering WebGL is based on OpenGL ES, and most mobile devices implement ES.

It's likely just a matter of perf. on mobile devices. If the browser's rendering/compositing is itself using too much of the GPU's resources to simultaneously run anything worthwhile in WebGL, it's probably not worth exposing it.

Well, mobile games use the GPU all the time, I don't see why web apps can't. Browsers could prompt before using it, that's what the BlackBerry PlayBook does.

I only get blank on Mobile Safari
