This is kind of off today's topic, but I have an unrelated question.
Working in 2d space, given 3 points, I know how to compute a circle (center/radius) that passes through those three points. Now I need to compute the direction of curvature of the 3 points. In other words, moving from the 1st point through the second point to the 3rd point, is the direction of the circle clockwise (curving right) or counter clockwise (curving left.)
Thanks,
Curt.
