Semantic Modelling of Interactive 3D Content

Abstract

Interactive three-dimensional content is the primary element of virtual reality (VR) and augmented reality (AR) systems. The increasing complexity and the use of VR/AR systems in various application domains requires efficient methods of creating, searching and combining interactive 3D content, which could be used by people with different specialities, who are not required to be IT-experts. The Semantic Web approach enables description of web resources with common semantic concepts. However, the use of semantic concepts may also facilitate creation of 3D content. The main contribution of this paper is a method of semantic modelling of interactive 3D content. The method leverages semantic constraints between different components of 3D content as well as representations of 3D content at different levels of abstraction. It can be used with a multitude of domain-specific ontologies and knowledge bases to simplify creating and searching of reusable semantic 3D content components and assembling complex 3D scenes from independent distributed elements.
