Abstract
Three-dimensional content offers a powerful medium enabling rich, interactive visualization in virtual and augmented reality systems, which are increasingly used in a variety of application domains, such as education, training, tourism and cultural heritage. The creation of interactive 3D presentations is typically a complex process covering diverse aspects of the content such as geometry, structure, space, appearance, animation and behavior. Recent trends in the development of the semantic web provide new opportunities for simplifying 3D content creation, which may be performed at different levels of abstraction and may encompass the inference of hidden knowledge, which may influence the created content. However, the available approaches to 3D content creation do not enable conceptual knowledge-based modeling of 3D content. The main contribution of this paper is an approach to semantic creation of 3D content. The proposed solution leverages the semantic web techniques to enable conceptual, knowledge-driven content creation. The proposed approach has been implemented and evaluated. It has been shown that the approach can significantly simplify modeling of advanced 3D content presentations in comparison with the available approaches.
Highlights
Widespread use of interactive 3D technologies has been recently enabled by the significant progress in hardware performance, the rapid growth in the available network bandwidth as well as the availability of versatile input-output devices
Declarative content description significantly facilitates automatic content management in repositories by referring to content attributes, which may conform to common schemes and ontologies
The semantic modeling of interactive 3D content (SEMIC) approach leverages the semantic web techniques to satisfy the requirements for modeling of 3D content, which have been specified in Sect
Summary
Widespread use of interactive 3D technologies has been recently enabled by the significant progress in hardware performance, the rapid growth in the available network bandwidth as well as the availability of versatile input-output devices. Dependencies between components of interactive 3D content may include, in addition to its basic meaning and presentation form, spatial, temporal, structural, logical and behavioral aspects. Creating and composing interactive 3D content on the web are more complex and challenging tasks than in the case of typical web resources. The potential of VR/AR applications accessible on the web can be fully exploited only if the interactive 3D content is created with efficient and flexible methods, which conform to the recent trends in the development of the web. Semantic description of web content makes it understandable for both humans and computers, achieving a new quality in building web applications that can “understand” the meaning of particular components of content as well as their relationships, leading to much better methods of creating, searching, reasoning, combining and presenting web content
