Timing controls on paint brush/ drawing programs
Jan 5th, 2010, 9:55pm  
In this sketch

http://openprocessing.org/visuals/?visualID=6838

I created a simple program and would like it to function like a drawing program for example like a Photo Shop brush.

How could I make the lines continues no matter how fast the speed of the mouse is going?

How can I make sure that any where the mouse has been that it draws the line as appropriate?

Could I make it draw the line with the mouse courser no matter how fast the mouse was moving consistantly across all computers?

The usual way is to draw lines between each mouse coordinate you get. Might look not so nice if mouse moves really fast, but alternatives (like drawing Bézier curves) are much harder to code!

You cannot, because it also depends on the speed at which the system report the mouse positions, and you can add Java layer over that, and Processing layer too...

Even harder... Smiley But I don't think you should be concerned by that, users rarely have different systems at hand, so they will get used to the behavior of their own system.
