[vtkusers] How to insert points to construct a 3d object

[Melissa Goh]

Hi David,

I have attached a screenshot of the 3d object. Below is my code snippets:

*vtkPolyData strip = new vtkPolyData();
vtkPoints points = new vtkPoints();

for (int i=0; i<xyz.length; i++){
     points.InsertNextPoint(xyz[i][0], xyz[i][1], xyz[i][2]);
}
strip.SetPoints(points);

vtkSurfaceReconstructionFilter surface = new
vtkSurfaceReconstructionFilter();
surface.SetInput(strip);
vtkContourFilter cf = new vtkContourFilter();
cf.SetInputConnection(surface.GetOutputPort());
cf.SetValue(0,0.0);

vtkReverseSense reverse = new vtkReverseSense();
reverse.SetInputConnection(cf.GetOutputPort());
reverse.ReverseCellsOn();
reverse.ReverseNormalsOn();
reverse.Update();

vtkPolyDataMapper map = new vtkPolyDataMapper();
map.SetInput(reverse.GetOutput());
map.ScalarVisibilityOff();
*
Appreciate your help! :)

Thanks,
Melissa
