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

Slide 3 of 10
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 M+S
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”)
 “Stuck” in CAD and DCC tools 

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
