碩士 === 國立臺灣大學 === 資訊網路與多媒體研究所 === 100 === Making facial animation of 3D characters is a difficult and time consuming work since there are over hundreds of controllers for facial expressions, and even slight differences may create different emotions. We present an interactive facial animation creation system reusing high quality animations. This system can not only assist novices to produce facial animations more quickly, moreover, it can be used as a communication tool between artists and directors for shooting scripts without repeatedly editing. To help an artist to efficiently find the animation needed in our system, we propose a novel method employing retrieval approaches for 3D facial expressions. Different from usual face expression recognition methods, we use depth maps of character face as our input data, and extract depth features and curve features. The system doesn’t require a special rigging system, and the result is stable.
