Q: 

How to find orientation of a bezier curve?

How to find orientation (cw or ccw) of a closed curve that's formed by Bezier cubic segments?

+1  A: 

It's the same as the orientation of the control polygon. See http://stackoverflow.com/questions/1165647/how-to-determine-if-a-list-of-polygon-points-are-in-clockwise-order and http://www.cgafaq.info/wiki/Simple%5FPolygon%5FOrientation

Thanks! It's a really simple algorithm and it's working! :)
