SV: [vtkusers] using GetNumberOfTriangles()

[Tron Darvann]

This code will get the number of cells.

If you only have triangles, it will be the number of triangles.

// Read the surface (VTK type in this example)

vtkPolyDataReader *surf = vtkPolyDataReader :: New();

surf -> SetFileName(filename);

surf -> Update(); 

// Put surface points in Points

vtkPoints Points = Surf -> GetPoints();

// Get the number of cells, e.g. triangles

ncells = Points -> GetNumberOfCells();

Hello,
does someone know how to use the function GetNumberOfTriangles() to get the
numbers of triangles for a 3D model?
thanks
