[vtkusers] How can i render different data and write it to same screen at di fferent areas

[Shanker Krishnan]

Hello,

I have 3 sets of data. They vary radially. I want to render it using raycast
and write to screen. Then i have another set of data which i want ot render
and write it around the circumference of the previously rendered image. And
this goes on for the third data. Is there anyway i can do it in VTK using
the raycastmapper. Please help me out.

Thanks in advance.
