Autonomous presentation of 3 dimensional CG contents on the Web

Abstract

Web3D technologies have made it possible for users to browse and manipulate 3D CG model data on the Web. Usually, such data requires users to interact with it in order to see its attribute information and its attached behavior. To automatically present 3D CG data and its attribute information, it is necessary to create 3D CG animation in advance. However, much time and cost is needed to create 3D CG animation that introduces its shape and its attribute information. We aim at constructing a mechanism that automatically produces 3D CG animation from the original 3D CG model data and its attribute information. 3D CG data has become popular on mobile phones such as i-mode. It is, however, difficult for users to interact with such data on mobile phones, because of their limited interaction capability and small-size screen. To cope with the problem, we also need to have a mechanism that produces 3D CG animation in an autonomous manner. We propose a way to automatically generate 3D CG animation from the original 3D CG model data and its attribute information. With the proposed method, users can browse 3D CG data and its attribute information in a less clicking and more watching manner. The proposed system automatically generates CG animation synchronized with synthesized speech from 3D CG contents and their attribute data. We also propose a method to generate a presentation for multiple 3D CG objects, that emphasizes the major differences in their attribute information.
