Method Details

intersectLineQuadCurve

public static @NonNull IntersectionResult intersectLineQuadCurve(@NonNull Point2D a0,
 @NonNull Point2D a1,
 @NonNull Point2D p0,
 @NonNull Point2D p1,
 @NonNull Point2D p2)

Computes the intersection between quadratic bezier curve 'p' and the line 'a'.

The intersection will contain the parameters 't' of curve 'a' in range [0,1].

Parameters:

a0 - point 0 of 'a'

a1 - point 0 of 'a'

p0 - control point P0 of 'p'

p1 - control point P1 of 'p'

p2 - control point P2 of 'p'

Returns:

the computed intersection
