Adding Cartoon-like Motion to Realistic Animations

In comparison to traditional animation techniques, motion capture allows animators to obtain a large amount of realistic data in little time. In contrast, classical animation requires a significant amount of manual labour. The motivation behind our research is to look at methods that can fill the gap that separates realistic motion from cartoon animation. With this knowledge, classical animators could produce animated movies and non-realistic video games in a shorter amount of time. To add cartoon-like qualities to realistic animations, we suggest an algorithm that changes the animation curves of motion capture data by modifying their local minima and maxima. We also propose a curve-based interface that allows users to quickly edit and visualize the changes applied to the animation. Through our user studies, we determine that the proposed curve interface is a good method of interaction. However, we find that in certain cases (both user-related and algorithmic), our animation results exhibit unwanted artefacts. Thus, we present various ways to reduce, avoid or eliminate these issues.
