I have tried it. It is not giving good results on the sphere's example. Also somehow this depth peeling is not working at all on my mesh. I ran into some more problems using the vtkDepthSortPolyData if used for multiple polydata seperately. It seems that this apporach works only when we have a single actor. While my requirement is that i want to be able to change transparency multiple actors at will also. If i do not append them the result is not fine and it seems that there are some angles at which the back back actors are rendering in front. My problem is described earlier as well: <br><br><span><a target="_blank"

But when i introduced vtkDepthSortPolyData it slows down the application interaction a bit. Can anyone please let me know that if there's a work around for such behavior. Can it be made faster. I want to keep different actors so that i can adjust transparency of each of them individually at run time.<br>
