[vtkusers] SetAspect does nothing???

[Greg Scott]

Hi there,

I am trying to set the aspect ratio of a perspective rendering using
vtkViewport->SetAspect. However, different settings have no effect what so
ever. I believe this is because I'm using OpenGLRenderWindow. Does anyone
know the work around for this?

Many thanks for any responses.

Greg
