[vtkusers] Reading a single 3D file?

billo, here's a small tcl snippet that should help

# Simple volume rendering example.

I have a single file that contains 3D data (32-bit signed integers).
I know the dimensionality, etc. and I want to read in the file
to do volume rendering.

In reading "The Visualization Toolkit User's Guide," I see
how to read in a volume from a series of 2D images, but nothing
to read in 3D data from one file of ints.

Is there a "read raw" command in VTK?


Thanks!
