Shape Semantics
The world surrounding us is to an increasing degree described as 3D objects in computers. These descriptions carry much knowledge. However, the programs handling the knowledge communicates to a limited degree. Knowledge in one system is not accessible from another system. To facilitate better integration of systems semantic descriptions in the form of ontologies play a central role. SINTEF has participated in two EU funded initiatives related to the semantics of shape. The Network of Excellence Aim@Shape (2004-2007), and the Coordination Action FOCUS K3D (2008-2010).

AIM@SHAPE

AIM@SHAPE was a Network Of Excellence (NoE) in EU's fp6 addressing  shape and semantics. SINTEF had the role as tecehnical coordinator, with IMATI from Italy as the adminstrative coordinator. The results of AIM@SHAPE can be found in the Digital Shape Workbench that comprises four parts: 

  • Shape Repository
  • Tool Repository
  • Tool Repository
  • Ontology and Metadata Repository

AIM@SHAPE has facilitated the establishment of an European network of researchers and organizations that are interested in shape and semantics.

FOCUS K3D

FOCUS K3D (2008-2010) is Coordination action in EU's fp7 addressing the future evolution of of shape and sematics. SINTEF had the role as tecehnical coordinator, with IMATI from Italy as the adminstrative coordinator. The has focused for applciation domains:

 

The Requirement from Isogeometric Analysis for Changes in Product Design Ontologies

Isogeometric analysis introduced in 2005 by Professor Thomas J.R. Hughes, replaces traditional Finite Elements with volumetric NURBS (NonUniform Rational B-Splines). Although mathematically this seems to be a minor adjust, it will drastically change the model life-cycle in a Finite Element Analysis (FEA). Consequently product design ontologies addressing FEA, such as the Aim@Shape Product Design Ontology (PDO), have to be revised to include the potential of isogeometric analysis. The PDO employs the Aim@Shape Common Shape Ontology (CSO) that also has to be revised. NURBS curves and surfaces have been used extensively in Computer Aided Design (CAD) the last two decades. Preprint of paper will be made avaialble.
