- Sentence: We present a novel technique for stroke interpolation from only two keys which combines a stroke motion constructed from logarithmic spiral vertex trajectories with a stroke deformation based on curvature averaging and twisting warps.
- Problem: The process of tight inbetweening by hand requires large amounts of time and technical skill in comparison to other inbetweening which relies more on artistic expression. In order to automate tight inbetweening, interpolation between key frames should follow a natural motion arc, while still allowing the artist to step in as needed.
- Key Idea: Operating on images decompsed into stroke graphs, interpolate between cooresponding strokes by using logarthimic spirals, for stroke motion, and curvature averaging and twisting warps, for stroke deformation.
- Application: Demonstration of the proposed technique compared with hand drawn originals. Also demonstrated how an artist can guide the process by specifying motion paths, correcting incorrect stroke pairs, and inserting additional strokes for occluded surfaces.
- Usefulness: Could be used to create a quick animator’s sketch book by allowing the animator to only concentrate on the key frames – it wouldn’t be perfect, but it would allow a rough idea of the final animation to be created.
