[vtkusers] VTK draw POINT ERREUR when x,y and Z are big

[messari.omar]

HELLO, 
I'm trying to display my points (data comming from a magneto sensor) the 
datas are between -600 and 600 i can't show them and i have a message error 
that tells me that the format i'm trying to enter are incorrect. 
but when i normalise my values ( -1<value<1) i can see my point on the 
windowscontrol so i don't know what is the problem and how i can fix this, 
to show the values between -600 and 600. 

this is my code: 

private void Point() 
        { 

            // Create the geometry of the points (the coordinate) 
            vtkPoints points = vtkPoints.New(); 
            List<double> X = new List<double>(); // création de la liste 
            List<double> Y = new List<double>(); 
            List<double> Z = new List<double>(); 

            // Create topology of the points (a vertex per point) 
            vtkCellArray vertices = vtkCellArray.New(); 
            
            double a =  double.Parse(reader.MAGx.Text); // data comming from
the sensor 
            double b =  double.Parse(reader.MAGy.Text);// data comming from
the sensor 
            double c = double.Parse(reader.MAGz.Text);// data comming from
the sensor 
            X.Add(a); 
            Y.Add(b); 
            Z.Add(c); 
            label7.Text = a.ToString(); 
            int[] ids = new int[X.Count]; 
            for (i = 0; i < X.Count; i++) 
                ids[i] = points.InsertNextPoint(X[i], Y[i], Z[i]); 

            int size = Marshal.SizeOf(typeof(int)) * X.Count; 
            IntPtr pIds = Marshal.AllocHGlobal(size); 
            Marshal.Copy(ids, 0, pIds, X.Count); 
            vertices.InsertNextCell(X.Count, pIds); 
            Marshal.FreeHGlobal(pIds); 

            // Create a polydata object 
            vtkPolyData pointPoly = vtkPolyData.New(); 

            // Set the points and vertices we created as the geometry and
topology of the polydata 
            pointPoly.SetPoints(points); 
            pointPoly.SetVerts(vertices); 

            // Visualize 
            vtkPolyDataMapper mapper = vtkPolyDataMapper.New(); 
            mapper.SetInput(pointPoly); 
            vtkActor actor = vtkActor.New(); 
            actor.SetMapper(mapper); 
            actor.GetProperty().SetPointSize(2); 
            vtkRenderWindow renderWindow =
renderWindowControl1.RenderWindow; 
            vtkRenderer renderer =
renderWindow.GetRenderers().GetFirstRenderer(); 
            renderer.AddActor(actor); 
            renderWindow.Render(); 
        } 

Thanks all.
