Dear all!<br>
<br>
Is there anything available in vtk that I simply haven't found yet for<br>
smoothing some polygonal data?<br>
<br>
I have a closed polygon in 3D space (although it's actually located on a<br>
plane) which is stored as vtkPolyData. Unfortunately, it consists of<br>
quite a lot of points, even in regions of low curvature. Is there any<br>
filter that can remove some of the points automagically?<br>
<br>
Best regards,<br>
