Tutorial: "Collada and WebGL"
An overview of WebGL based on OpenGL ES 2.0 that provides an imperative API for 3D graphics. Also included in this workshop is an overview of COLLADA an open standard digital asset schema for interactive 3D applications.
Chair: Remi Arnaud

Tutorial: "Advanced X3D"       
X3D is a royalty-free file format and run-time player specification that is compatible with many 3D technologies. X3D is also designed for reuse of content and archival publication, making it particularly well suited for government use.
Attendees in this tutorial will gain the following knowledge: X3D capabilities as publishing format for 3D graphics on Web, X3D players, both commercial and open source, X3D authoring and quality-assurance tools, X3D import, export and conversion capabilities and Case studies. All attendees provided with latest X3D Showcase DVD for all resources.
Chair: Don Brutzman (Naval Postgraduate School)

Tutorial: "MPEG-4, MPEG-V, MPEG Part 25"       
Driven by the development of applications such as games, simulations and immersive environments, and thanks to continuous hardware improvements over the last few years, synthetic graphics content has become a very important media type on part with video, audio and images. Even ordinary computers can now render complex 3D graphics assets and synthetic scenes. However, unlike video, audio and images the 3D graphics media chain remains a complex one. There are no single acquisition devices yet that are able to capture and reconstruct a synthetic 3D representation of real objects and scenes and their creation is still based on the existence of authoring tools, typically complex software programs assisting graphics artists. What is worse is that each authoring tool has its own internal data structure and there are several tens of proprietary formats for storage.
On the other hand, there is an increasing demand for network-based distribution of media, including 3D graphics coming from on-line media sharing services and distributed applications, while the complexity and 3D objects and scenes increases.
Therefore there is a need for a common standard representation of 3D graphic information supported by all authoring tools and effective compression algorithms for transmission. "MPEG 3D Graphics" goal is to define a standard format for compressed 3D synthetic content. In other words to be for graphics what MP3 and AAC are for audio, MPEG-2 and MPEG-4 are for video and JPEG is for still images. The benefits of using MPEG 3D Graphics are faster and more cost-effective application development, assets reusability and perennity, more efficient storage and on-line distribution services.
The tutorial will expose the new developments of MPEG towards this goal.
Chair: Marius Preda (Institut Telecom)

Tutorial: "Building Networked Virtual Worlds"       
X3D Graphics includes the ability to integrate a variety of networking technologies to build distributed shared 3D environments. This Tutorial will explain and demonstrate the use of DeepMatrix shared avatar server, BitManagement's multiclient-server software, past work using the DarkStar massive multiplayer online game (MMOG) server, url refresh capabilities for simple server-side push of behaviors and geometry, and the widely used IEEE Distributed Interactive Simulation (DIS) protocol. Emphasis will be on how creation of shared virtual worlds is feasible by using X3D graphics for interoperability, thereby avoiding being locked into proprietary technologies that may become unavailable over the long term.
Chair: Nicholas Polys (Virginia Tech)

Workshop: "Geo Visualization"       
Real world applications are finally becoming a truly open system of Geo referenced 3D scenes. Many 3D geospatial capabilities and components are now available. The next challenges facing workshop attendees and the larger community are to demonstrate how these open standards and open assets can all work together in effective and complementary ways. The workshop will include an overview of X3D-Earth and how to demonstrations and examples of data mash ups with X3D-Earth. Also discussed will be how 3D models stored in open or proprietary formats can be used with different delivery mechanisms based on open standards-based formats and services.
Chair: Peter Schickel (Bitmanagement)
Contributors: Nicolas Paparoditis (Institut Geographique National)

Workshop: "Augmented/Mixed Reality"       
This workshop presents an overview of Augmented Reality and X3D, how real environments and virtual environments can bring us a Mixed Reality experience on the Web. Different extensions and systems will be presented and discussed to build a true mixed reality experience. Topics include strategies for low-level tasks like device handling and integrating sensor inputs, as well as highlevel setups for various interaction methods. Furthermore, more advanced Mixed Reality visualization methods, such as occlusions between virtual and real objects and relighting, will also be discussed in the context of X3D.

Workshop: "Scientific & Medical Visualization"       
In this workshop, we will explore and discuss how Web3D technologies can be used to provide a collaborative environment for visualizing different kind of scientific data over Internet. It means working on the whole processing chain from the numerical simulation results datasets to the end user remote visualization tool including scientific data processing, 3D data validation and cleaning, data compression, transmission, decompression/remote rendering and scientific visualization. Through our talks, several demonstrations will point out different works and the enclosed prospects in various domains as Medical, Fluid Dynamics, and Forensics.

Workshop: "CAD"       
CAD models tend to have complex geometry and metadata, captured in proprietary formats. This workshop will discuss the long-running efforts to consistently expose complex CAD models as lightweight X3D models, implementation of the Compressed Binary Encoding (CBE) for reduced file size and faster loading performance and evaluation of Boundary Representations (B-REPS) in X3D and use of Macro-Parametric Translation for conversion of many CAD formats.

Workshop: "Remote Rendering"       
The computing domain met last years a growing tendency to outsource the application execution process, from the client to the network. This so called cloud computing approach allows to benefit from new released applications, even with thin-end devices, and also favors the users access, “everywhere and anytime”, to their data and applications.
From both industrial and academic point of views, this workshop will address the main issues and optimization opportunities when designing a remote rendering system: What are the key parameters of a remote rendering architecture? Which data representation and format to choose in order to optimize the QoE? How to make profit of the information provided by the renderer to improve the QoE?

Workshop: "Declarative 3D"       
There are upcoming open (e.g. WebGL) and proprietary (e.g. Adobe) proposals for imperative graphics APIs in the Web context but we are missing an easy way to add interactive high-level declarative 3D objects to the HTML-DOM to allow anyone to easily create, share, and experience interactive 3D graphics with possibly wide ranging effects similar to those caused by the broad availability of video on the Web. This workshop will discuss the requirements, options, and use cases for an integration of interactive 3D graphics capabilities into the W3C technology stack.
Chairs: Philipp Slusallek (DFKI)

Workshop: "New user experiences with an internet 3D: games, training, collaboration"       
Navigating into 3D contents accessible over the internet is something well done since more than a decade. However when it comes to develop consequent applications, popular 3D scene languages that includes basic descriptions for interactions were too limiting for efficient gaming and virtual training. Nowadays, we are turning back to scripted solutions that make it possible to develop more heavy 3D applications with customized and rich interactions which fit with those high-leveled requirements. This workshop will give examples of such 3D applications or needs in several domains such as video games, e-learning and collaborative work.

Panel Session: "Positioning, requirements and interoperability of Standards"       
There is an host of 3D standards currently available to develop research prototypes and industrial applications: X3D, Collada, WebGL, MPEG, OGC, etc. Faced with this alphabet soup of standards, it is a challenge to clearly understand their various characteristics and suitability to a given requirement set. In addition, many of these standards provide complementary functionalities and can be used together to improve a project's bottom line. During this panel session, leaders of the various groups will explain how their standards can help to easily develop applications across various domains such as Geo-visualization, Augmented Reality, Distant Rendering, Virtual Worlds, Serious Gaming, E-Learning etc. Because interactive information spaces on the web continue to evolve, it is important that attendees learn how they can participate in the Web3D community and help improve the standards for the future. Finally, as interoperability between standards is a necessity (the web has demonstrated it), the presenters will introduce the different joint works that are currently in progress among their various consortia.

Please notice that the 2nd day of the Conference, the June 21, the "Fete de la Musique" will take place in the streets of Paris all night long (and everywhere in France). Completely different from a music festival, the "Fete de la Musique" is above all a free popular "fete", open to any participant (amateur or professional musicians) who wants to perform in it. This Music day allows the expression of all styles of music in a cheerful atmosphere. It aims at a large audience, working to popularise musical practice for young and not so young people from all social backgrounds. It gives an opportunity to communicate and share a very special moment through music. The musicians are asked to perform for free, and all the concerts are free for the public.
