[vtkusers] Rendering multiple actors

[Muralidharan Dhanakoti]

Hi vtk users,

I guess my actors on the render window are scaled relative to the largest 
actor , for instance when I draw just a bezier curve, the curve is displayed 
just fine in the render window, but when I add another actor say a polygon, 
the curve and the polygon seem to be scaled (down) by some factor. 

Is this problem due to the fact that I'am not defining the clipping volume for 
the renderer, something that we do in OpenGL using 
glOrtho(xmin,xmax,ymin,ymax,zmin,zmax). 


Thanks,
Murali.
