[vtkusers] How to refresh the screnn

[Wenlong Wang]

Sorry I attached wrong code. Here is the function
void CVTKDialogDlg::ShowLandmarks(double current_mode[][3])
{
 CRect rect;
 CWnd* p = GetDlgItem(IDC_SHOW_FACE);
 p->GetClientRect(&rect);

 int index;
 double x, y, z;
 for (int i = 0; i < sizeof(landmarks)/sizeof(double); i++)
 {
  index = landmarks[i];
  x = current_mode[index][0];
  y = current_mode[index][1];
  z = current_mode[index][2];
  //newpoints->InsertPoint(vtkIdType(i), current_mode[index][0],
current_mode[index][1], (current_mode[index][2])+0.2);
  newpoints->InsertPoint(vtkIdType(i), x, y, z+0.2);
 }
 newpolydata->SetPoints(newpoints);
 gf = vtkVertexGlyphFilter::New();
 gf->AddInput(newpolydata);
 gf->Update();
 newarray = vtkFloatArray::New();
 for (int j = 0; j < sizeof(landmarks)/sizeof(double); j++)
 {
  newarray->InsertTuple1(vtkIdType(j), double(j));
 }
 newpolydata = vtkPolyData::New();
 newpolydata->GetPointData()->SetScalars(newarray);
 newmapper = vtkPolyDataMapper::New();
 newmapper->SetInputConnection(gf->GetOutputPort());
 newmapper->SetScalarRange(0, 7);
 newmapper->SetScalarVisibility(0);
 newactor = vtkActor::New();
 newactor->SetMapper(newmapper);
 newactor->GetProperty()->SetColor(0.0, 1.0, 0.0);
 newactor->GetProperty()->SetPointSize(10);
 ren->AddActor(newactor);
 renWin->AddRenderer(ren);
 renWin->SetParentId(p->m_hWnd);
 renWin->SetSize(rect.right-rect.left, rect.bottom-rect.top);
 ren->Render();
 renWin->Render();
}

Yes, I checked it and am sure that it is called as the slider moved.

It looks like the points moving without refreshing the screen.

Thank you very much

Long
