@PanicsAtCaller Public Function Union(a: Vec2[][], b: Vec2[][]): Vec2[][]

The region filled by either a or b, or both. A corner that isn't finite panics.

Examples


Local a = [[Vec2(0, 0), Vec2(2, 0), Vec2(2, 2), Vec2(0, 2)]]
Local b = [[Vec2(1, 0), Vec2(3, 0), Vec2(3, 2), Vec2(1, 2)]]
Expect(PolygonArea(Union(a, b)) == 6.0)
Expect(PolygonArea(Intersection(a, b)) == 2.0)
Expect(PolygonArea(Difference(a, b)) == 2.0)
