Hello Sascha and List, thanks for the patch. I try it and worked fine. As you pointed out, the 2D views run extremely low.
btw, in general, MITK has trouble with 2D rendering of meshes: - when more than 2-3 meshes are rendered, turns low - also when zooming do you guys experience the same? is vtkPolyDataCutter really slow in generating contours? one good source of test data is http://www.ircad.fr/softwares/3Dircadb/3Dircadb2/index.php there are CT datasets and segmentations, both as labeled images and vtkPolyDatas. Loading 2-3 of such organ meshes make the application run really slow. best regards, sebastian On Fri, Feb 12, 2010 at 2:57 PM, Sascha Zelzer <[email protected]> wrote: > Hi Sebastian, > > unstructured grid support is indeed broken, I have opened bug #3337 at > http://bugs.mitk.org/show_bug.cgi?id=3337 .
