An Interactive Sketch Modeling And Animation System

This paper proposes a sketch-based modeling and animation system. Most traditional modeling and animation systems requires users have professional techniques and outstanding 3D perception, and the animation designers must perform a precise adjustment on the rigid skeleton position and angles for each key frame, which usually costs several hours to complete an animation. We here propose a modeling and animation system for non-expert users whose interactive format is sketching completely. In our system, we design a new soft curve skeleton to represent the model animation and deformation. By using this new curve skeleton, users can establish skeleton by sketch and design animation conveniently, and it will cost only several minutes to finish an animation work. Our system allows non-expert users to easily design and create non-precise models and animations.
