<DIV>Hi, </DIV>
<DIV> do you want to get more than one render windows? or do you want to get more renderers in the same render window?</DIV>
<DIV> 1, if you only want to get more render windows, you could create some objects of vtkRenderWindow, and use function SetSize() and SetPosition() to arrange these render windows.</DIV>
<DIV> 2, if you want to get more renderers in the same render window, you can do it as follows (this codes have two renderers in the same render window) :</DIV>
<DIV> vtkRenderer * ren1 = vtkRenderer::New();</DIV>
<DIV> vtkRenderer * ren2 = vtkRenderer::New();</DIV>
<DIV> vtkRenderWindow * renWin = vtkRenderWindow();</DIV>
<DIV> renWin->AddRenderer( ren1 );</DIV>
<DIV> renWin->AddRenderer( ren2 );</DIV>
<DIV> ... ...</DIV>
<DIV> ren1->SetViewport( 0, 0, 0.5, 1 );</DIV>
<DIV> ren2->SetViewport( 0.5, 0, 1, 1 ); // use this function !</DIV>
<DIV> ... ...</DIV>
<DIV> you can see the function <STRONG>SetViewport()</STRONG> of class vtkRenderer to get more information in details if you want to add more renderers in the same render window.</DIV>
