Computational geometry is the research field that relates to the shape, description, and properties of physical objects. SINTEF Oslo has been a key player in this field for five decades. Our research combines computer science, mathematics, approximation theory, and numerical analysis with deep knowledge of application domains. Below, you can find highlights from our activities.
SAGA (2008-2012) is is aimed at training young researcher in applied and algebraic geometry. The network comprises 5 university partners, 3 research institutes and 2 IT-companies. The coordinator is SINTEF Chief Scientist Tor Dokken, Read more..
The introduction of Isogeometric analysis in 2005 by Prof. Tom Hughes has trigger a major research effort to extend spline technology has to from curves and surfaces to volumes. Read more..
The spline research in SINTEF has it roots in the first spline course lectured (1976) at the University of Oslo (UO) by Prof. Tom Lyche, and is now a integral part of the spline research at UO's Centre of Mathematics for Applications. Read more..
From the start of our work on polynomial splines in 1978 our ambition has been to make available our research results and technology through the development of Software Toolkits. Read more..
The world 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. Read more..
Our first intersection algorithms based on recursive subdivision of spline curves were implemented in 1980. Our work continued to surfaces in 1984. In 2005 we had progressed to surface self-intersections. The next steps will be to address intersection challenges posed by isogeometric analysis related to rational trivariate splines. Read more..
Combining parametric and implicit representations is important when making efficient algorithms for Computer Aided Design (CAD).Read more..
SINTEF in Oslo has addressed CAD-related challenges for five decades. Now the research is concentrated on advanced representation and processing of geometry with a focus on spline technology. Read more..
