We are about to switch to a new forum software. Until then we have removed the registration on this forum.
How come when I draw a shape like line, circle, triangle etc it is smoother in setup than draw? smooth() seems to only work for setup. I have tried OPENGL and other modes people suggested in other threads, not sure why it works like this though.
Never mind, I am a dummy, forgot to draw the background so it was drawing over itself several times.
And in new version of processing smooth(); is enabled as default. Try experimenting with setting noSmooth();
As you found out, it is a Technical FAQ...
Why are text and graphics so ugly and blocky?
At least, this topic is one more reference / entry point to this FAQ! ;-)
