public static IntersectionResult intersectQuadCurveQuadCurve(Point2D a0,
 Point2D a1,
 Point2D a2,
 Point2D b0,
 Point2D b1,
 Point2D b2,
 double epsilon)

Computes the intersection between quadratic bezier curve 'a' and quadratic bezier curve 'b'.

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

Parameters:

a0 - control point P0 of 'a'

a1 - control point P1 of 'a'

a2 - control point P2 of 'a'

b0 - control point P0 of 'b'

b1 - control point P1 of 'b'

b2 - control point P2 of 'b'

Returns:

the computed result
