style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">This works (with some other
quirky behaviour which I have circumvented). But a problem that I am having
difficulty with is that the clipping planes remain as if the geometry hadn’t
been altered. Thus, as I rotate the object (in trackball camera mode) the
displaced object disappears. I have checked the bounds of the viewable
objects (using Renderer->ComputeVisiblePropBounds(bounds) ;) and they are
unaltered – thus all the AutoClipping is thrown out of whack. It may very
well be that (a) I am doing things that are not meant to be catered for in
vtk or (b) there is a better (preferably simpler) way of achieving this
effect. <o:p></o:p></SPAN></FONT></P>
