In recent years, three-dimensional Virtual Environments developed with virtual reality and graphical computation technologies have evolved in the Web. Thus, users with different profiles, cultures and knowledge levels can access such environments remotely. In such a way, it is necessary to use an efficient interface to manage Web accesses and to actualize virtual environments to adapt them to each...
Aiming to solving bottleneck problems such as modeling 3D scene and character in the process of virtual product development, this paper investigates a data-driven synthesis of geometric model, and applies to a shape-based search to find 3D models or parts in a model base, and then composite parts to form new models. Its application shows that this approach can efficiently create geometric models of...
This paper describes a face-muscle model system capable of emoting avatars in a variety of applications. The presented model produces dynamically changing facial expressions on computer generated faces, using mathematically modeled muscle deformations. The muscle model used to distort sets of vertices in a 3D space, is independent of the geometric model and hence it can be applied to arbitrary face...
