    • intersectQuadCurveLine

      public static @NonNull IntersectionResult intersectQuadCurveLine(@NonNull Point2D p0, @NonNull Point2D p1, @NonNull Point2D p2, @NonNull Point2D a0, @NonNull Point2D a1)
      Computes the intersection between quadratic bezier curve 'p' and the line 'a'.

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

      Parameters:
      p0 - control point P0 of 'p'
      p1 - control point P1 of 'p'
      p2 - control point P2 of 'p'
      a0 - point 0 of 'a'
      a1 - point 1 of 'a'
      Returns:
      the computed intersection
