[vtkusers] Adaptive / on-demand visualization with VTK

[Marcel Prastawa]

I would like to visualize a volume data that can be manipulated in real 
time. Generating data for each point involves rather expensive 
computations (also defined dynamically), a brute-force algorithm is not 
desirable.

What I envision is an algorithm that would divide the volume and 
generate data incrementally. It would take the camera/eye location into 
account and only generate/display new data for parts of the volume that 
are visible (or updated).

Has something like this been done with VTK?

Any hints or suggestions on how I should approach this? (What VTK data 
types or filters to use, efficiency tips, etc).

I would appreciate any advice or comments from the VTK community.
