Hi young chun‌,

Please refer to this page: Getting a WebGL Implementation

Here they say:

WebGL 1.0 is supported in the stable releases of most major browsers on both desktop and mobile platforms. Chrome, Firefox, Internet Explorer, Opera, and Safari are all known to have good WebGL support on both desktop and mobile browsers.

But:

Technical issues such as known hardware problems or lack of required GPU features may prevent WebGL from running in some cases.

HTH,

Egge-Jan
