Summary:
A Sketching Interface is introduced in this paper named Teddy. The system can automatically convert the 2D stroke drawn by user into 3D polygonal surface. The process of is really convinient for users, which is showed in their user study that creating models is not hard even for first time users. A standard polygonal mesh is used to represnet the 3D picutre. The experiment shows the system is robust and can finish the task in short time.
Discussion:
It is interesting that converting 2D to 3D can be supported. It is also an efficient way to deal with 3D models if we need just draw a 2D shapes, which is easier. It is very useful that users can see the result while he or she draw the 2D shape, which allow them to modify it quickly.
