The XMSF Challenge

• XMSF
• Getting the data modeled, simulated,
  synchronized, and visualized
• On the Web
• Compression, streaming, multi-res
• Network bandwidth, latency and QOS
• Open standards, heterogeneous clients,
  scalability
• Extensibility
• diverse apps, diverse feature requirements

• Performance
• Scalability
• Consistent Playback
• Synchronized sims
• Efficient, reliable networking

Focus issue Getting Web-friendly data

The Authoring Challenge

• Easy" integration of 3D Models and Simulations
  for presentation/collaboration on the Web
• Readily available indexed 3D Models
• Readily available simulation behaviors
• Tools for Modeling, Sims, and MS
• Inexpensive, low learning curve, high
  productivity and flexibility
• Wysiwig
• Consistent playback
• Quick feedback to the content developer
• Support for legacy models/sims (converters, or
  backwards compatibility)

3D Models for the Web

• Model availability
• Numerous standard formats
• VRML/X3D, IGES, STEP, DXF, HOOPS, OBJ,
  W3D,
• Repositories and search engines
• 3dcafe.com, TurboSquid, Deep Exploration,
• Format converters
• E.g., Deep Exploration, PolyTrans, importers,
  exporters,
• Modeling tools numerous CAD and DCC tools
• Web players
• Xj3D, OpenWorlds, Shockwave3D, MetaStream,

So where is the Web3D content?

• Takes seemingly forever to get 3D models on the
  Web
• ProEngineer ? 3D Studio Max ? Shockwave3D 3
  weeks
• A medical lab scene took 6 months to convert to
  X3D.
• Problems
• The formats are not quite complete, and lack
  broad acceptance
• VRML player size, performance
• DXF textures, compression, lighting, materials
• W3D, HOOPS community extensibility
• X3D compression, streaming, multi-res
• No Wysiwig
• Converters and players are buggy
• Lack of conformance (certifications)

Time
? Stuck in CAD and DCC tools ?

An open visualization format

• CAD 3D Working Group
• Part of the Web3D Consortium
• First meeting 9/5/2002
• Current member organizations
• Intel, Boeing, BMW, Dassault, Yumetech,
  Adobe, ATI, 3D Labs, NPS, Microsoft,
• http//www.web3d.org/fs_workinggroups.htm

CAD3D WG Next Steps

• Identify requirements
• Evaluate options
• Specification
• Reference implementation
• Process / certification

Summary

• Cost of Authoring is a key issue
• CAD and DCC data is not web-friendly
• Formats are incomplete, not wysiwig
• CAD3D WG formed with complimentary goals
• XMSF will need importers, exporters, tools
• For Models
• For Sims
• For Scenarios
