<FONT face="Geneva, Arial, Sans-serif">Hi,</FONT><BR><FONT face="Geneva, Arial, Sans-serif"> I don't know what's your name. maybe you need two renderers in the same render window, and then you could render two different volumes in them.</FONT><BR><FONT face="Geneva, Arial, Sans-serif"> you can do like this :</FONT><BR><FONT face="Geneva, Arial, Sans-serif"> <FONT color=#0000ff>vtkRenderWindow * renWin = vtkRenderWindow::New();</FONT></FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> vtkRenderer * ren1 = vtkRenderer::New();</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> vtkRenderer * ren2 = vtkRenderer::New();</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> renWin->AddRenderer(ren1);</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> renWin->AddRenderer(ren2);</FONT><BR><FONT face="Geneva, Arial, Sans-serif"
color=#0000ff> </FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> // your original pipeline</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> ... ...</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff></FONT> <BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> ren1->SetViewport( 0, 0, 0.5, 1);</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> ren2->SetViewport(0.5, 0, 1, 1);</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> ... ...</FONT><BR><FONT face="Geneva, Arial, Sans-serif" color=#0000ff> renWin->Render();</FONT><BR><FONT face="Geneva, Arial, Sans-serif"> </FONT><BR><FONT face="Geneva, Arial, Sans-serif"> using this, you could divide the whole
render window into two parts, and then you could do what you want to in the two different renderer. </FONT><BR><FONT face="Geneva, Arial, Sans-serif"> hope this could help you.</FONT><BR><FONT face="Geneva, Arial, Sans-serif"> Mark</FONT><BR><BR>
