If you encounter the message below when launching BRAIN, it is possible that WebGL is not enabled on your browser.

What is WebGL?

WebGL is a specification for web browsers that enables 3D viewing on the web.

WebGL enables complex 3D graphics to be viewed, created and managed in a client's web browser window. It is currently implemented in most browsers, but, as this implementation is recent, this technology remains relatively unknown to the general public.
