<DIV><FONT face=宋体 size=2>Hi, all</FONT></DIV>
<DIV><FONT face=宋体 size=2></FONT> </DIV>
<DIV><FONT face=宋体 size=2>I manually create a polydata by assigning the
vtkpoints and scalardata.</FONT></DIV>
<DIV><FONT face=宋体 size=2>By now, the polydata does not have any cells
inside.</FONT></DIV>
<DIV><FONT face=宋体 size=2>But if I want to contour it, cells are needed. (Is
that right?)</FONT></DIV>
<DIV><FONT face=宋体 size=2>I have try vtkDelaunay2D and vtkDelaunay3D as a
filter.</FONT></DIV>
<DIV><FONT face=宋体 size=2> But after the filter are applied, the
GetOutput()->GetNumberOfCells() still gets 0.</FONT></DIV>
<DIV><FONT face=宋体 size=2></FONT> </DIV>
<DIV><FONT face=宋体 size=2>Why ? Help!!</FONT></DIV>
<DIV><FONT face=宋体 size=2></FONT> </DIV>
<DIV><FONT face=宋体 size=2>Thanks.</FONT></DIV>
