ISMAS: An Interactive Sketch Modeling and Animation System

This paper proposes a sketch-based modeling and animation system. Most traditional modeling and animation systems require users to have professional techniques and outstanding 3D perception in order to perform precise adjustments on the rigid skeleton positions 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 with only sketch interactions. 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 the animation task. Our system allows nonexpert users to easily design and create non-precise models and animations.
