In this paper, we present a hybrid of graph-based and neural network modeling system of Chinese Ancient Pagoda (CAP). To implement the pagoda modeling system, we have built a basic element model library of pagoda by L system and a corresponding feature ...

Haptic rendering is a growing concern of research community worldwide. However, it is a great challenge to haptically render complex objects. In this paper, a novel haptic rendering algorithm via directional sampling is proposed. We propose haptic box, ...

Skeletons and shape components are important shape features, and they are useful for shape description and shape understanding. Techniques to extract these features from volume data are analyzed in this paper based on multiple distance transformations. ...

In this paper we present a novel 3D animation system using a set of easily manipulable space canvases that support free-hand drawing. Our aim is to support the traditional free-hand drawing while improving the functionality by imitating the 3D animation ...
