<P>This code will get the number of cells.</P>
<P>If you only have triangles, it will be the number of triangles.</P>
<P>// Read the surface (VTK type in this example)</P>
<P>vtkPolyDataReader *surf = vtkPolyDataReader :: New();</P>
<P>surf -> SetFileName(filename);</P>
<P>surf -> Update(); </P>
<P>// Put surface points in Points</P>
<P>vtkPoints Points = Surf -> GetPoints();</P>
<P>// Get the number of cells, e.g. triangles</P>
<P>ncells = Points -> GetNumberOfCells();</P></FONT>
