intersectQuadCurveEllipse

public static @NonNull IntersectionResult intersectQuadCurveEllipse(@NonNull Point2D p0,
 @NonNull Point2D p1,
 @NonNull Point2D p2,
 @NonNull Point2D c,
 double rx,
 double ry)

Computes the intersection between quadratic bezier curve 'p' and the given ellipse.

The intersection will contain the parameters 't1' of curve 'p' in range [0,1].

Parameters:

p0 - control point P0 of 'p'

p1 - control point P1 of 'p'

p2 - control point P2 of 'p'

c - the center of the ellipse

rx - the x-radius of the ellipse

ry - the y-radius of the ellipse

Returns:

the computed result. Status can beIntersectionStatus.INTERSECTION, Status#NO_INTERSECTION_INSIDE or Status#NO_INTERSECTION_OUTSIDE}.
