Re: [Paraview] interpolation

[John Biddiscombe]

I found that modifying vtkProbeFilter to make use of a BSP/OctTree improves performance significantly when large numbers of sample points are used for probing. I can't remember if I kept the change I made to probefilter, but if I did, they are in the pv-meshless source tree. JB Hi all, I'm thinking of writing an interpolation filter for Paraview in order to transfer data from one 3D grid to another efficiently using some kind of octree.  Has this already been done ? I have used the Resample with dataset filter in the past, but this does not give accurate results on my test cases, also I believe it is not very efficient.  Any hints about where to start, or classes to look at ?  Cheers, Jacques _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview -- John Biddiscombe, email:biddisco @ cscs.ch http://www.cscs.ch/ CSCS, Swiss National Supercomputing Centre | Tel: +41 (91) 610.82.07 Via Cantonale, 6928 Manno, Switzerland | Fax: +41 (91) 610.82.82
