[vtkusers] clear screen

[Gopalakrishnan, Gowri]

Hi All, 

 

I would like to clear the screen of any display before I do the step two in
my routine.

I tried renderer -> Clear(); followed by renderwindow->Render()

 

Nothing happened. The screen still had the display from the previous step.
Is there anything

Else I should do to clear the screen?. 

 

Thanks

Gowri
