  • Method Details

    • intersectQuadCurveLine

      public static IntersectionResult intersectQuadCurveLine(Point2D p0, Point2D p1, Point2D p2, Point2D a0, 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
