I was reading the Three.js wikipedia page and it states "Three.js runs in all browsers supported by WebGL." If you use canvas renderer will the application/game created with Three.js run in browsers that support canvas but not webGL. Also are there any know issues with Three.js and mobile browsers.
Actually all browsers are supported which have support for canvas. We do not support polyfilled canvas. Mainly because most of the time, we use other things beside the canvas that are not implemented by the browser.
