Geometry2D nodes simplify creation of simple planar shapes, which can be helpful for billboards and user interfaces.

Geometry2D nodes simplify creation of simple planar shapes. Planar geometry includes the Arc2D, ArcClose2D, Circle2D, Disk2D, Polyline2D, Polypoint2D, Rectangle2D and TriangleSet2D nodes. Each Geometry2D node is placed individually inside a Shape node.
