[vtkusers] RE:How to display points in VTK

[Alam, Mohammed]

Hi Bob,

I tried to visualize the following and the result was a white (blank)
window with no points. Not sure what I am missing...

x[0][0] = 0;
            x[0][1] = 0;
            x[0][2] = 0;
            x[1][0] = 0;
            x[1][1] = 1;
            x[1][2] = 0;
            x[2][0] = 1;
            x[2][1] = 0;
            x[2][2] = 0;
            x[3][0] = 1;
            x[3][1] = 1;
            x[3][2] = 0;
		vtkPoints newp = new vtkPoints();
            vtkCellArray newv = new vtkCellArray();
            
            int nump = 4;
            int pp = 0;
           
             while( nump-- > 0 )
             {
           	int id1 = newp.InsertNextPoint(x[pp][0], x[pp][1],
x[pp][2]);
                 newv.InsertNextCell(id1);
                 
                pp++;
             }

             vtkPolyData pd = new vtkPolyData();
             pd.SetPoints(newp);
             pd.SetVerts(newv);

          vtkPolyDataMapper mapper = new vtkPolyDataMapper();
          mapper.SetInput(pd);
          vtkActor cubeActor = new vtkActor();
              cubeActor.SetMapper(mapper);
		 vtkRenderer renderer = new vtkRenderer();
          vtkRenderWindow renWin = new vtkRenderWindow();
          renWin.AddRenderer(renderer);

          vtkRenderWindowInteractor iren = new
vtkRenderWindowInteractor();
          iren.SetRenderWindow(renWin);
          renderer.AddActor(cubeActor);
          renderer.SetBackground(1,1,1);
		renWin.SetSize(600, 600); 
            renWin.Render();
            iren.Initialize();
            renWin.Render();
            iren.Start();
Thanks
