Multiplatform 3-D Graphics

The focus of our research is enabling the users to interact with three-dimensional (3-D) graphics and interactive applications with the same content, appearance, and interaction paradigm on different platforms [Internet, television (TV), and mobile devices]. The main contribution of this article is the design and implementation of a platform-dependent architecture for 3-D graphics and content, validated in the entertainment and tourism sectors. Nowadays, people are accustomed to using different interactive platforms in their daily lives. Digital TV is consolidating as the main interaction platform at home, while laptops and desktop computers are still the most important working tools in the office. The mobile devices in both private and working environments have a growing impact. Presently, there are more mobile devices in the world than a combination of PCs and TVs [1]. Multiplatform applications are becoming more and more frequent in daily life. This article is organized as follows. The first section describes the currently available architectures for different platform applications. Then the proposed architecture is presented as well as the two sectors (entertainment and tourism) where the architecture will be validated. While in the former, 3-D contents are mainly virtual characters (or avatars) that represent people, the contents in the latter are tourist attractions such as buildings, sculptures, monuments, etc. Finally, some conclusions of this work are obtained.
