Evaluates the circular segment function for a given x.
Note that only the first two derivatives are implemented, all higher orders will return NaN.
Implements rl::math::Function< Vector2 >.

Generates a circular segment function in 2D through three given points.
The given points most not be (numerically close to) colinear.

inlinestatic |
Generates a circular segment through three given points in 2D with a given segment angle.
The given points must not be (numerically close to) colinear. Contrary to ThreePoints, where the circular segment ends in y1, the circular segments ends after a given angle. With this, a full circle can be constructed, given an angle of 2*pi. The given segment angle may be any real number, which allows multiple rotations.

Angle of circular motion.
Any real value is allowed.
|
protected |
First axis of the circular motion.
Note that at time 0, the function value is (center + axisX).
|
protected |
Second axis of the circular motion.
After a motion of 90 degrees, the function value is (center + axisY).
