Re: Question -- Lattices

[slevy]

Need to check what (graphically) you mean by a lattice -- is it a
regular array of isolated points in N-dimensional space?

If so, the answer to both your questions is Yes.  Geomview 1.4.2 has an
"nSKEL" format that lets you specify points (and line segments) in
N-space.  Then, Geomview plus the NDview module could display projections
of them into 3-space.  You could make Mathematica write nSKEL files
directly, then read them into Geomview.

Alternatively, the existing OOGL.m/Geomview.m programs can handle Mathematica
"Point" objects.  They also support running Mathematica on one machine and
Geomview on another (see ``??DisplayHost'' after loading <<Geomview.m).
If you project your lattice into a collection of 3-D points using mathematica,
you could display it directly using something like

    << Geomview.m
    SetOptions[Geomview, DisplayHost -> "annap at some-iris.stanford.edu"]
    latticepoints = { {0,1,.5},  ... }	(* List of 3-d points *)
    Show[ Graphics3D[ Map[ Point, latticepoints ] ] ]
