DEADLINE EXTENSION: Call for Papers Web3D 2008 - Infrastructure Evolution 13th International Symposium on 3D Web Technology August 9, 10 2008 LA Convention Center Sponsored & Co-Located w/ ACM SIGGRAPH http://www.web3d.org/conferences/web3d2008 Ecosystems of tools & techniques are evolving for standards-driven technologies. Web 3D technologies leverage the latest informatics tools such as XML-based solutions, web services applications, and graphics hardware innovations to deliver solutions across many domains. Topics include languages, tools, rendering techniques, human-computer interaction, networked and mobile devices and innovative applications. As in previous years, this event will be sponsored by ACM SIGGRAPH and held in cooperation with both EuroGraphics and the Web3D Consortium. Thirteenth in the series, the Web3D 2008 International Symposium will address this wide range of topics covering 3D Hypermedia on the Web. The annual Web3D Symposium is a major event, which unites researchers, developers, experimenters, and content creators in a dynamic learning environment. Attendees share and explore methods of using, enhancing, or creating new 3D Web and Multimedia technologies, such as (but not limited to) X3D, VRML, COLLADA, Croquet, MPEG4, MPEG7, Java3D, and Canvas3D. The symposium will also focus on recent trends such as interactive 3D graphics and applications on mobile devices. Authors are invited to submit their work (short or full papers) for review by the international Program Committee. Both research and applications papers are of interest to Web3D 2008. The papers must be innovative and contribute to the advancement of 3D Multimedia technologies on the Web. Topics of interest include but are not limited to: . Interactive 3D graphics and immersive systems for servers, desktop and thin clients, . High-performance 3D graphics for Virtual Worlds, MMOs, Augmented Reality, and interactive on-line gaming . Animated humanoids and complex reactive characters (e.g. avatars) . Integration and interoperation with 3D Documents and Web/Multimedia technologies, including the Semantic Web . Methods for modeling and rendering complex geometry, structure and behaviors . User-interface paradigms and interaction methods for real-time 3D graphics and virtual environments . Innovative 3D graphics applications for Web/Multimedia in industry, science, medicine, and education Authors are invited to submit full papers of up to 9 pages (including figures and references) or short papers of up to 4 pages (including figures and references) in PDF format via the Symposium Submission Site. Papers must be formatted using the document templates for conferences sponsored by ACM SIGGRAPH. After acceptance, the final revised paper is required also in camera-ready electronic form. Accepted papers will appear in the Symposium Proceedings, published by ACM Press. Schedule Full & Short Paper submission deadline: April 21, 2008 [EXTENDED] Author Notification : June 2, 2008 Camera-ready due : June 13, 2008 Note that authors who have already submitted papers are permitted to upload modifications or updates up until the deadline.
