X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• Fraunhofer Foundation• Mission: “Application oriented research for
industry and advantage of our society “
• Figures 2007
• 62 Institutes
• 13 600 Employees
• 1.3 Billion € Budget
• 2/3 research projects for industry
• 1/3 public funding
• Institute for Computer Graphics, Darmstadt
• 120 Employees
• 20 Employees in VR/AR Group
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• 15 Years of research in VR/AR• 1st Generation
• 1992 start of VR-Activities• 2nd Generation
• 1994 1st Fraunhofer VR System• 1994 First 5 sided CAVE in Germany• 1995 Founding VR-Spinoff: VR-COM
• 3rd Generation• 2000 OpenSG (LGPL Scene Graph)• 2002 Avalon VR System (X3D based)• 2005 InstantReality VR/AR Middleware• 2008 HEyeWall 2.0 ( 35 Billion Pixel)
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• Increasing need for a flexible runtime environment
• Scalability is key requirement• Application Behavior
From Walkthrough to complex non-linear storytelling/game environments
• Interaction and NavigationFrom stateless single device => Sensor-Fusion Systems with complex device setups
• Image synthesis/RenderingFrom PDA to Multi-Screen/CPU/GPU-Cluster
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• There is no Standard for VR/AR applications and runtime systems
• X3D ISO Standard, describes an abstract functional behavior and time-based interactive 3D environment
• Multi-parent Scenegraph• Behavior-graph• Runtime System• IO Device Independent• High level interaction• Portable• Xml/classic/binary encodings
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• X3D utilized as basis for an VR/AR application description language• Solid ISO foundation• Extensibility leaves room for
VR/AR extensions and research• Immersive interaction• Distributed rendering• Mixed Reality
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• “Beyond the Desktop” Interaction• Low-level data-stream sensors for direct data access
(e.g. 6D tracker, images).
• X3D PointingSensor in Immersive Environments
• UserBody nodes/states trigger PS
• UserBody nodes transform rays and collision obj.
• Multi-UserBody-nodes lead to multi-hand/user
• Additional unrestricted 6D PS-extension
• Navigation Framework
• Works seamless with X3D Bindable concept
• Allows flexible method prototyping (e.g. go-go)
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• Distributed Rendering• Sort-first and Sort-last support• Dynamic load distribution
• Fully automatic method• 2x to 5x performance increase
with typical CAD data• Scales almost linear with
GPU/CPU Boxes
X3D: Real Time 3D Solution for the web Web3D Tech Talk – SIGGRAPH 2008
• Mixed Reality Lighting • Real-time global illumination
using Precomputed radiance transfer
• Updates shading form video-stream in real-time
• Details in Web3D 07/08 paper• Live-demos at the Web3D-booth
