[vtkusers] Update VTK Poly data in vtkRenderWindow

[Gishara Indeewarie]

Hi David,

Option is selected using radio buttons.
eg: When user selects temperature option data should be changed to display
temperature values.
(only the scalar values are changed. Not the x, y, z values of the points)
But when I call  renderWindow->Render()   it creates a new window. I want
to update data in the same window.

Thanks.
