I would be grateful for some advice on volume and surface rendering in Paraview.
I am trying to generate 3D skull models from CT data. The reason for using Paraview is to take advantage of the detailed fly-through/movie capability. I can generate an acceptable 3D model that I can interact with in OsiriX and 3D Slicer, both of which I believe use VTK. However, in Paraview I am struggling to create a 3D model that looks any good. When I apply a threshold filter and view as a ‘Surface’ the image is a lot more ‘blocky’ than in the other two applications. The image is dominated by the artifactual lines due to the original data being acquired as axial slices; whereas in OsiriX and 3D Slicer this gets smoothed out and the ‘genuine’ surface skull features (sutures etc) stand out. I realise this is probably question of apply the correct series of filters and that the other two apps do this ‘under the hood’. However, i have tried to apply Decimation and Smooth to the extracted surface and am not making any headway. Any pointers would be very welcome M _______________________________________________ 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 Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
