crossProductXYXY MethodStatic

2D cross product of vectors with the vectors presented as numbers.

• Sign of 2d cross product is positive <=> sweeping from first vector to second vector is ccw orientation.
• Sign of 2d cross product is negative <=> sweeping from first vector to second vector is clockwise orientation.
• 2d cross product is 0 <=> parallel/antiparallel vectors.
