Interactive exploration of big scientific data: New representations and techniques

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1418941

Although splines have been in popular use in CAD for more than half a century, spline research is still an active field, driven by the challenges we are facing today within isogeometric analysis and big data. Splines are likely to play a vital future role in enabling effective big data exploration t...

Locally refined splines representation for geospatial big data

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1279120

When viewed from distance, large parts of the topography of landmasses and the bathymetry of the sea and ocean floor can be regarded as a smooth background with local features. Consequently a digital elevation model combining a compact smooth representation of the background with locally added featu...

Locally refined spline surfaces for representation of terrain data

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1259469

In this paper we describe the use of a novel representation, LR B-spline surfaces, and apply this representation in the treatment of geographical data. These data sets are typically very large and LR B-spline surfaces offer a compact representation of overall smooth data with local details. We brief...

Compact Representation of Big Geospatial Data by Locally Refinable Splines

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1259143

The EC fp7 Integrating Project www.iqmulus.eu addresses the representation and processing of big geospatial data in the Cloud. One of the objectives is to address smooth ocean floor and provide LR-spline algorithms for accurate and compact approximation of hundreds of millions of data points acquire...

Numerical Methods for Implicitisation and Their Applications

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1181402

Modern methods in computer aided design and manufacturing (CAD/CAM) allow geometries of almost arbitrary shape and topology to be created. However, CAD/CAM software has long been plagued by problems of robustness when it comes to modelling the results of operations such as intersections. Such geomet...
