Raw data plays very well with Volumizer. There are several ways to skin
this cat. Thankfully the TIFF image format will accomodate 3 dimensions
of imagery. Take your raw data and convert it to .tif format.
Assuming your file is named "raw_128.dat" the conversion command on
IRIX is:
% imgcopy "raw_128.dat#raw%size=128,128,128%colormodel=luminance"
out.tif
% imginfo out.tif
% voglBasic out.tif
imginfo should report that out.tif is 128^3 pixels of luminance data.
If your data is not a power of two you will have to truncate or pad the
data beforehand.
Best,
Ken Schwarz
