[vtkusers] Render big data

[pegga]

Hi all,

I am dealing with large data rendering. My data is typically 3D matrix of
intensity values (int or float).
Data can be quite large - several GB sometimes even more.

Issue 1)
When trying to render data bigger than 2000 x 2000 x N (X, Y, Z dimension) I
get OpenGL errors. When data is smaller in X and Y (let say 1700 x 1700)
everything goes well.

Issue 2)
How to proceed when rendering data which is obviously too large to fit GPU?
I thought about rendering data block by block sequentially, but I cannot
find right tools.

Thanks,
Petr
