We haven't discussed last week's thoughts and
ideas too much on this list, and the midterm report
will be due soon.

So I hope you fully realise the limitations of an
"interpolate 2D slices and stack them into a 3D
volume" approach. Its results will divert
from those of a true 3D interpolator that works
in voxel space.

If you have trouble with NVIZ, then you can use
r3.out.vtk to export your voxel data to VTK and
load that into a VTK-based view (e.g. ParaView).
Use r.out.vtk, v.out.vtk, accordingly.

Best,

Ben
