[vtkusers] volume rendering of matrices?

[Roman Putanowicz]

Hi Fredrik,
You can create object of class vtkStructuredPoints, get point data
from it (vtkPointData), get scalars array from it and fill the array.

I attached a quick and dirty example how to do it. In this example 
the array is filled from the file (raw binary file), 
but it can be filled from anything.

I hope this will help.

Cheers
