Geometry Knowledge synergies

• Semantics .. not limited to modeled objects
• and also expands to multimedia data (images,
  video, audio)

Semantically enhanced models

Scenarios in CAD/CAE and Virtual Product Modeling

• Semantic procedural models - what is it?
• are for 3D what pdf is for text pages
• Characteristics and potentials
• High reusabilbity
• Paradigm shift towards generic models
• Inherent semantics
• Rules and reasoning
• Procedural matching

Conclusion

• Open issues / major problems
• non-existent links between 3D models and product
  properties/characteristics/behaviour
• Re-use for geometric components
• Less knowledge about interfaces and kinematic of
  cybernetics
• Visualization of production technologies shape
  constraints
• Global shape modelling
• Creation/Re-use of surface/volume CAD models
  containing partitions

18
Conclusion

• More Open issues / major problems
• Unfold geometries for surface parametrization
• PDM for the whole product life cycle
• Effective similarity search methods
• Structural similarity as a concept
• Effective querying controls
• Contextualize 3D objects
