Subject: [vtkusers] Question about vtkCamera


Hello,
I define my vtkCamera and set it in vtkRenderer as the following code:
  Camera = vtkCamera::New();
  Camera->SetPosition(0,0,-20  );
  Camera->SetFocalPoint( 0,0,0 );

  ren1=vtkRenderer::New();
  renWin->AddRenderer(ren1);
  ren1->SetActiveCamera(Camera);

It is very strange that when I render it, it does not display. Only when I
click the mouse button, it will display. Because I have set
vtkRenderWindowInteractor, the window will be updated when I click mouse
button. Why does it not display in the beginning? How can I do? Please give
me some hints. Thank you very much!


Chunyan
