- def calcControlPoint(p1: R2, p2: R2, bend: Double = 0.0): R2
Calculate the location ('x', 'y') of the control point.
Calculate the location ('x', 'y') of the control point. It is positioned orthogonal to the mid point of the line connecting 'p1' and 'p2' at a distance 'dist', where 'dist = bend * || p2 - p1 ||'. A bend of 0.0 gives a straight line, while 2.0/-2.0 gives a huge bend up-right/down-left.
- p1
the starting point
- p2
the ending point
- bend
