Call for Papers The goal of the special issue is to collect a broad range of papers on perspective applications of 3D content, a rapidly emerging new form of media in the semantic multimedia panorama and an extremely challenging context of application of semantic multimedia. The issue is promoted by the FP7 EC FOCUS K3D project, and it is expected to provide an up-to-date view of the open issues in knowledge intensive 3D media, and trace future research and technological directions. The special issue addresses scientists not only in Computer Graphics but also in all the disciplines that make strong use of 3D modelling and simulation; professional developers of tools for 3D content creation and management; publishers/dealers of online 3D repositories; creators of digital 3D content. We call for contribution on topics related to semantic 3D media and applications, including but not limited to: * semantics-based 3D modelling and processing * semantics-driven 3D shape segmentation * content-based 3D retrieval and classification * semantics-driven 3D visualization * 3D media ontologies * formalization of shape semantics * smart objects and virtual characters * automatic creation of imaginary worlds * semantics-driven interaction in D worlds Contributions should be formatted according to the Elsevier style guide and submitted online (http://ees.elsevier.com/cag/). Detailed instructions will be made available on the web site of the FOCUS K3D project (http://www.focusk3d.eu). All submissions will undergo a two-stages review cycle according to the standard of the Computers & Graphics Journal.

In the near future 3D data will represent a huge amount of traffic and data stored and transmitted using Internet technologies. 3D media, as a term which encompasses all forms of digital content about 3D objects used and managed in networked environments, are not only fancy-looking graphics used in entertainment applications : 3D media are endowed with a high knowledge value carried either by the expertise needed to design them or by the information content itself. 3D media are key in many applied sectors such as Medicine and Bioinformatics, Gaming and Simulation, CAD/CAE and Virtual Product Modelling, Archaeology and Cultural Heritage. In these applied sectors, representing a complex shape in its complete life-cycle stages is known to be highly non trivial, due to the sheer mass of information involved and the complexity of the knowledge that a shape can reveal as the result of a modelling process. 3D media introduced therefore a new kind of content in the multimedia scenario. At the same time, research on semantic multimedia, as the deep integration of semantic web techniques with multimedia analysis tools, has shown how to use and share content of multiple forms, endowed with some kind of intelligence, accessible in digital form and in distributed or networked environments. The success of semantic multimedia largely depends on the extent at which we will be able to use them in systems that provide efficient and effective search capabilties, analysis mechanisms, and intuitive re-use and creation facilities, at the level of content, semantics and context.
