Representation schemas are not interchangeable

• Triangle mesh is not just a different syntax for a solid...

Common Shape Ontology

RacerPro provides reasoning

Geometric representations don't capture the semantics of the objects

• The only place this exists is implicitly in segmentation
  • Part-based decomposition, etc
  • Could get better results by coupling ontologies with feature recognition

Shape annotation

No clear approach to linking annotations to 3D data

• How to refer to the specific elements?
• What happens if the shape is deformed or the representation medium is changed, e.g., solid to mesh?
