3. 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 Navigation From stateless single device => Sensor-Fusion Systems with complex device setups Image synthesis/Rendering From PDA to Multi-Screen/CPU/GPU-Cluster

4. 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

5. 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

6. 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)

7. 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
