Positions MUST be float, so you can't save there. Data probably can be cast to int() or byte() generally speaking. I don't think any modules would promote it back to float, but I'm not 100% sure on that (it might happen invisibly inside the module for interpolation purposes, i.e., promote, then demote). To get the full advantage of casting down, create a net that does nothing but Import, Compute(int(a)), Export. Process all your data files first. Then use the new small-data files in the actual viz net. Otherwise, all the float data you import takes up space in ADDITION to the new int arrays you create on the fly.
If you have so many points, the ShowPositions cloud will be pretty obvious. If you must have zillions of glyphs, buy a Mac G5 with OS X and put in about 4 Gb. I did, and I ran a job a couple weeks ago that used 1.8Gb of memory (2 being the limit at the present time, per app.)
The best I could do on a PC with 2Gb installed was 1.2Gb for DX, which is I believe the process limit in Windows.

My data are in floating point but such precision exceeds reasonable
bounds when the diameter of a 3D speedy glyph exceeds it that fineness
by orders of magnitude. So I am thinking an integer function might
save me gobbs of memory. Might that possibly be so?
My purpose is to have paired data sets as 3D scatter graphs for the
XYZ load signatures of automotive antivibration motor mounts. OpenDX
is just the thing...but some of the data sets run into megabytes. And
I can't load a pair of them even on my 512MB NetBSD box at home.
TIA,
