I am starting to look at WebGL and the first thing I noticed is that the rendering quality of graphics inside the browser is of a very high quality and that this does not appear to come at the expense of performance. In my own OpenGL C or Java applications I am unable to achieve such high quality rendering either by specifying the number of samples or by manually fiddling with the NVIDIA driver antialiasing settings in the Control Panel (on Windows).
So, how does WebGL achieve such high quality rendering? It seems to be completely independent of the driver settings and looks crisper than any application that I have seen running on the desktop. Ideally I would like to use the same techniques (antialiasing?) in my own non-web applications.
