<DIV id=RTEContent>hello,</DIV> <DIV> </DIV> <DIV>I have an open surface in the form of a vtkPolyData.</DIV> <DIV> </DIV> <DIV>Now my algorithm gives a list of connected points in the whole model.</DIV> <DIV> </DIV> <DIV>For example, if u consider the model of a human body, and say my algorithm gives the list of all points on the nose in the form of another vtkPolyData</DIV> <DIV> </DIV> <DIV>Now i want to use these list of points to extract the nose from the whole vtkPolyData model of the human body.</DIV> <DIV> </DIV> <DIV>One thing to note, the geometry corresponding to the list of points, will be connected , so no need to worry in that sense.</DIV> <DIV> </DIV> <DIV>Can anyone tell what filters of VTK i can use to achieve this task ? Given the list of points the filter should give me the corresponding geometry extracted from the whole model. It should pull out all the cells corresponding to these points.</DIV>
<DIV> </DIV> <DIV>Can vtkClipPolyData do this ? </DIV> <DIV> </DIV> <DIV>I can easily create a scalar array, with label for each point if it is inside or ouside my list of points. Will this be useful. OR is there anyother way ?</DIV> <DIV> </DIV> <DIV>Please help Me !!!!!</DIV> <DIV> </DIV> <DIV>Bye</DIV> <DIV> </DIV> <DIV>Deepak</DIV> <DIV> </DIV> <DIV> </DIV><p>
