OK.
However, when asked, ImageVis3D appears to import the file. It just asks
for the extent (number of points?) in each direction, i.e. 16,8,9.
Is this imported volumetric image I observe meaningful? Is the grey scale
presented in the image controlled by the number of bytes allowed by the
graphics card?
What would happen if I changed the file so that the intensity for points
outside the current data ranges, that is for points [1:16], [1,10:16]
[1:6,16], are zero?

Code in what language?
Also, is the amount of video memory just that which is on the (in my case)
embedded controller or does it include the TOTAL Available Graphics Memory =
Dedicated Video Memory + Share System Memory?
Thanks for your help. I hate to be such a nag but the software has such a
huge upside for the work I am doing that could help many people.

From a (very) quick read, I'd say this isn't a point cloud. It looks
as if your data's ranges are [1:16],[2:9],[7:15], and further there
are no `holes' in the data (i.e. no combination of those three indices
which is not represented). If this is true, you've got regular,
gridded data, which is exactly what we need for ImageVis3D.
If there's anybody in your group who can code, have them follow up on
tuvok-developers [1]. Otherwise I'll add an ASCII reader to my todo
list...

There's currently no support for this in ImageVis3D, though the request

If you've got a very small example (kilobytes), sending it to this

If it's anything larger, use ImageVis3D's builtin "Report an Issue"
