is a very commonly asked question on the list. Can anyone comment if the above
two methods are the best VTK has to offer as far as creating a surface from a
point cloud? I think the graphics community would claim that this is a
"solved" problem - but the results still seem rather bad!<BR><BR>Murat - the
MarchingCubes algorithm requires more than just the points - take a look

<DIV>VtkSurfaceReconstructionFilter needs many close points. What are the ways
of interpolating points in VTK in order to make points dense enough ? </DIV>
