I got an answer :
For Bézier curves, the tangent at the end point is collinear with the direction to the nearest control point. In this case, it means that for the two curves to be tangential, points B, C and D must lie on a straight line.
Hi,
I'm in 2D, and I have a Bézier curve defined by three points A, B, C.
I have two other points next to the curve, D and E, and I want to make a second Bézier curve C, D, E (having a common point (C) with the first curve).
My question is : How do I calculate the coordinates of point D to make the second curve continuous (tangent) with the first one.
I guess there are infinite possibilities to position point D to have the second curve continuous with the first one. What can I do?
Thanks
