<div>hi . I have to set up interactive frame rates. I created iren (object of <FONT size=2></div> <div>vtkRenderWindowInteractor). But iren does not give me "SetStillUpdateRate()" and "SetDesiredUpdateRate()" methods. I have seen those methods used in some examples. Is it a vtk version thing? I am using 4.4.2. Were these methods disabled later ? In any case, what is the way to use interactive frame rates? </div> <div> </div> <div>Thanks,</div> <div>Vishal</div></FONT>
