Better ways of vectorizing photos than Illustrator's Trace?
Are there any better ways of vectorizing photos than Illustrator's Trace? I don't have one of them Wacom boards so I can't really do this by hand.
How do I calculate the normal vector of a line segment?
Suppose I have a line segment going from (x1,y1) to (x2,y2). How do I calculate the normal vector perpendicular to the line? I can find lots of stuff about doing this for planes in 3D, but no 2D... more
