Abstract

Even though numerous Web3D technologies exist, most of them do not support a high-level, multi-disciplinary authoring process. Moreover, concepts of reuse are rarely provided. A component-based approach is introduced with the CONTIGRA architecture to construct interactive, three-dimensional applications, either stand-alone or web-based. The approach is entirely based on declarative XML documents describing the component imple驴mentation, its interface, as well as component configuration and composition of 3D user interfaces and virtual environments. Extensible 3D (X3D) is used as the scene graph basis. However, the resulting applications can be translated to other 3D tech驴nologies, too. Another advantage of the approach is reuse both at the implementation level and the higher abstract component level. This paper introduces the overall architecture and the XML schemas used for the component documents. It finally outlines the associated authoring process and tools involved.
