<DIV><FONT face=Arial size=2>Hi to all,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> I created the polygon data using
Marching cube algorithm(not using vtkMarchingCube) and decimated it using vtk
library class vtkDecimatePro.That decimated output is displayed in a MFC window
using OpenGL API calls.It is ok.But i want to apply smooth shading
effect to the 3D object.I don't know which is the shading initally .For smooth
shading,i used vtkPolyDataNormals. </FONT></DIV>
<DIV><FONT face=Arial size=2>Then i got extra points than the input.I don't know
which is the relation between the input of vtkPolyDataNormals and the new
created normal points of vtkPolyDataNormals.Is sufficeient for implementing
smooth shading ??.The normal existing for each triangle or each vertices ??
</FONT></DIV>
