Hey I need some help (obviously...otherwise I wouldn't be posting).
I'm trying to figure out how to split a cubic Bezier curve into two separate cubic Bezier curves at a specified point on the curve, but I can't seem to figure out how to do it. I know the control points, and therefore I know the equation.
Here's the equation as defined by Wikipedia:
(http://upload.wikimedia.org/math/5/e/3/5e32b674a98a9f70e492851f9ad92b61.png)
Where B(t) is a single point on the bezier curve, and Pn is the nth control point.
Any help would be greatly appreciated!
Edit: Added an example of what I'm talking about. I have a full Bezier (top) and I want to split it at a certain point (of which I know the "t" value for the equation) into two independent Bezier curves.
