Hi Yves, Do you want to actually cut the tetrahedra that the polydata geometry intersects? I don't know of anything that will do that exactly in VTK, but you could approximate it by using the vtkImplicitPolyDataDistance class with the vtkCutter to approximately cut the tetrahedra by the polydata.
If you DON'T want to cut the tetrahedra, you could write a plugin that computes the distance field from each point in the tetrahedral mesh using vtkImplicitPolyDataDistance, then thresholds the mesh to keep only tetrahedra where at least some of the points have a negative signed distance from the polydata. I hope that helps, Cory On Tue, Apr 14, 2015 at 4:18 AM, Yves Rogez <[email protected]> wrote: > Hello, > > I would like to know if there is a mean with paraview (or VTK, I could > write a plugin) to easily clip a tetrahedron based geometry and data (built > with a delaunay3D filter) with a polydata geometry (typically a triangle > mesh) ? > The implicit sphere-based clipping could be an approximation but an > explicit 3D function would be better for my application... > > Thanks, > > Yves > > _______________________________________________ > 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 > -- Cory Quammen R&D Engineer Kitware, Inc.
