Algorithm for refining freehand drawn curve

Algorithm for refining freehand drawn curve

Post by Jozsef Ferin » Sun, 21 Sep 1997 04:00:00



I'm looking for a fast algorithm to make a freehand drawn curve
"nicer", but it should keep the curve in the main shape _and_
location.  Given is the set of points the mouse pointer was
dragged thru.

Best regards,
  Jozsef

Have a look at Graphic Gems, volume 1, page 612:

1. Approximating freehand drawn curve with Bezier curves

Hi,
I need to do what Corel Draw does: when user draws a curve with his
mouse, the control points should be found automatically (as many as
needed) and the segments of the curve among them should be approximated
with Bezier cubic curves. How can I do this?
Thanks in advance,
-Marcin Sawicki
