getting rid of something previously drawn
Nov 17th, 2008, 2:00pm  
i need something to get rid of all that has been previously drawn every time, the draw() method is called.

is there any other possibility, than to draw a surface that covers the whole canvas? since i'm using 3d this gets really messy and is not satisfying...

isn't there anything that resets it all?

I am not too sure about 3D, but at least in 2D, the usual way is to use background() at the start of draw() to erase everything and draw again.

I checked a couple of 3D examples and that's what they do too: draw() is cumulative (drawing on top of previous draw results) so if you animate something, you need to reset canvas on each frame.
