<TITLE>Add two renderers to vtkBorlandRenderWindow</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2 FACE="Arial">Hi vtkusers,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I am trying to add two renderers to the same vtkBorlandRenderWindow (RenWin). The relevant part of the pipeline may look like this</FONT></P>
<P><FONT SIZE=2 FACE="Arial">RenWin->GetRenderer()->SetViewport(0.0, 0.0, 0.5, 1.0)</FONT>
<BR><FONT SIZE=2 FACE="Arial">RenWin->GetRenderer()->AddActor(actor1)</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">RenWin->GetRenderer()->SetViewport(0.5, 0.0, 1.0, 1.0)</FONT>
<BR><FONT SIZE=2 FACE="Arial">RenWin->GetRenderer()->AddActor(actor2)</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">By doing it this way, I wonder how many renderers I would get. How do I distinguish between or identify two renderes? Is there any way to define two renderers explicitly and add them to RenWin? Let me assume I have two Renderers in RenWin, I wonder which Renderer I would get when I call RenWin->GetRenderer().</FONT></P>
