I am new to the volumizer mailing list and have just been going through
the volumizer
user guide and examples..

I am trying to volume render vascular data - its a structured grid
data, i.e. its a sequence of
2D images, but they are not axis aligned (like a bent tube). It seems
like I have to generate
the volume geometry to reflect this. I have the object coordinates at
each lattice point of the
volume. So should I take short segments of the vessel geometry and
approximate them by
cubical segments and convert each of these into tetrahedra? The texture
data is topologically
equivalent to a 3D cube. Would this work?

Also, volumizer (in its examples) takes volumes of size such as
256x256x109 and constructs
just 1 brick of size 256x256x64. To make it use the full volume, is it
sufficient to pad the additional
slices so as to make it go up to 256x256x128. In this case, would it
render the full volume?

Thanks.
