Method Details

intersectRayQuadCurve

public static IntersectionResult intersectRayQuadCurve(Point2D ao,
 Point2D ad,
 double maxT,
 Point2D p0,
 Point2D p1,
 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:

ao - origin of ray 'a'

ad - direction of ray 'a'

maxT - maximal parameter value for ray 'a'

p0 - control point P0 of 'p'

p1 - control point P1 of 'p'

p2 - control point P2 of 'p'

Returns:

the computed intersection
