[vtkusers] Removing Volumes from the render window

[David Patch]

I am displaying and updating 3D images on a renderWindowControl in MS VS 8.
Every time I update the image, the control retains the previous copy.  My
question is how do I remove the previous image before updating with the new
one?

 

I think I should be removing the volumes to accomplish this.  However, the
call to GetNextVolume always returns null even though the GetNumberOfItems
returns the expected count.

 

                int j = renderer2.GetVolumes().GetNumberOfItems();

                for (int i = 1; i <= j; i++)

                {

                    vol2 = renderer2.GetVolumes().GetNextVolume();

                    renderer2.RemoveViewProp(vol2);

                }

 

Am I doing something wrong?  

Thanks in advance.
