Intersection computes the intersection point of the two lines using math.big.Float arithmetic.

OrientationIndex returns the index of the direction of the point point relative to a vector specified by vectorOrigin-vectorEnd vectorOrigin - the origin point of the vector vectorEnd - the final point of the vector point - the point to compute the direction to Returns CounterClockwise if point is counter-clockwise (left) from vectorOrigin-vectorEnd Returns Clockwise if point is clockwise (right) from vectorOrigin-vectorEnd Returns Collinear if point is collinear with vectorOrigin-vectorEnd.
