[vtkusers] how to implement space-leaping in vtk?

[Jagan Lakshmipathy]

Hi all,

I want to implement a "space-leaping" algorithm so that Volume Ray Casting
can be made faster. I found in some earlier postings that vtkRayBounder and
vtkProjectedPolyDataBounder classes can be helpful for this purpose, but in
recent versions of vtk these classes don't exist.

Any idea, how to proceed?. Any help is greatly appreciated.

thanks much

Jagan
