<DIV><FONT face=Arial size=2>I am trying to use vtkSurfaceReconstructionFilter
to reconstruct a surface from a set of points. I haven't been successful
yet.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(1) I declare an object of vtkPoints and initialize
it:</FONT></DIV>
<DIV><FONT face=Arial size=2> vtkPoints *points;</FONT></DIV>
<DIV><FONT face=Arial size=2> // initialize
points->SetPoint(...);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(2) then I pass it to
vtkSurfaceReconstructionFilter by using:</FONT></DIV>
<DIV><FONT face=Arial size=2> vtkSurfaceReconstructionFilter
*surface = vtkSurfaceReconstructionFilter::New();</FONT></DIV>
<DIV><FONT face=Arial size=2>
surface->SetInput((vtkPointSet*)points);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(3) then I perform isosurface
extraction:</FONT></DIV>
<DIV><FONT face=Arial size=2> vtkContourFilter
*isosurface;</FONT></DIV>
<DIV><FONT face=Arial size=2>
isosurface->SetInput(surface->GetOutput());</FONT></DIV>
<DIV><FONT face=Arial size=2> isosurface->SetValue(0,
0.0);</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>(4) then I pass to PolyDataMapper the output of
isosurface, etc...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Can anyone comment on my sequence of code and
please let me know if there is anything wrong with what I am doing?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thank you for your time and help,</FONT></DIV>
