Different render mode?

I just realize that you can change render mode in size(), like: size(100, 100, P3D) or size(100, 100, P2D) or size(100, 100, JAVA2D). For me P3D runs MUCH faster than the default mode(which looks like P2D or JAVA2D) but there seems to be some anti-aliasing with the default mode. I guess perhaps P3D uses graphic card acceleration? Any idea if this gonna work in browsers?
