Drawing and Animation Using Skeletal Strokes - Siu Chi Hsu & Irene H. H. Lee


"We are proposing skeletal strokes as a new vector based drawing primitive for general stroking and picture specification. With the skeletal strokes framework, users are freed from the dependence on the scanner to input expressive brush strokes for further processing; they can create these strokes interactively on the computer. Compared with previously proposed expressive strokes, the skeletal stroke framework has more general applications. It has, for example, an anchoring mechanism which could be applied to 21⁄2D animation. The high level abstraction of skeletal strokes makes it particularly attractive in terms of storage size and transmission efficiency. Its efficient implementation is favourable for incorporation into windowing systems and page description languages.
We shall demonstrate the various techniques with our drawing and animation system, Skeletal Draw, which uses skeletal strokes as the basic primitives. An animation sequence has also been made to show the effectiveness of creating 21⁄2D animation using pseudo-3D models."
