ConvexPolygon2D() [2/2]

G3D::ConvexPolygon2D::ConvexPolygon2D	(	const Array< Vector2 > &	pts,
		bool	reverse = false
	)

Points are counter-clockwise in a Y = down, X = right coordinate system.

Parameters

reverse

If true, the points are reversed (i.e. winding direction is changed) before the polygon is created.
