[vtkusers] Plausible bubbles

[Wang Q]

Hello vtk guys,


I simply use spheres as bubbles, but with solid appearance and default lightning by vtk, which looks not good. I suppose that texture, opacity, and lightning should be added to them to make them plausible.  I did some research, and tried different ways, but cannot get a great one. I was wondering if anyone did this before or have any hint to achieve something like the ones by below link.
