You should probably use OpenGL.  It's fast, and it's available for linux
as the Mesa libraries.  I know that it works with VW Smalltalk
(currently only under Win95/NT, but Terry Fleury just completed a
partial port of the Jun display system over to Mesa/Glut so it will soon
work under Unix).  If you have access to a WinTel box, you can evaluate
the Jun system to see if it meets your needs (I expect that it will). 
You can get the non-commercial version of VW Smalltalk from (for linux
and WinTel):

Jun is available from:

http://www.sra.co.jp/people/aoki/htmls/FreeSoftwareForSmalltalk.html

I will work over the next month (big vacation month, not much free time)
on getting Terry's Mesa port ready for general use.  Unless you want to
be programming graphics code all day long, you should really try out
Jun.

Given that I'm pretty excited about using Jun under linux, it's one of
my top priorities.  Unfortunately, I am about to go out of town until
the middle of January.

For those that are unfamiliar with Jun, it provides an OpenGL modeling
environment that lets you develop graphical models in the spirit of
Smalltalk (i.e., you can make changes to the models as you look at
them).  Jun is currently available for VisualWorks 2.0, 2.5, and 3.0. 
The model viewing sub-system currently only works for WinTel since the
system uses the Windows API libraries for displaying the models.  Terry
Fleury (one of Ralph Johnson's students this year) has made the system
so that it opens a Glut window for displaying the models.  He modified
the Glut code adding a new event that allows VW menus to be displayed
over the Glut window.  

So, the code "basically works" now.  What I was thinking about doing was
taking a look at his code and seeing if I couldn't get it to work with
the standard Mesa/Glut libraries.  I also want to be able to make the
modeling environment a bit more similar to that in the current Jun
system (with wheel widgets and menus adorning the model's window).

If people want to work on this, send me email (notice the anti-spam
address).  I'd be more than happy to mail the code out to anyone who
wants it.  As soon as we get everything right, we'll put the code up on
the Smalltalk Archive and we can see if Aoki would like to include the
code in the standard Jun distribution.

For those that want to wait 'til the project is complete, I anticipate
that it won't take more than 2 months (but if I get some volunteers it
could take only a week).

All in all, I'm pretty excited about this.  This could be a great
graphics environment for use under Linux (as well as other
platforms...).

You might want to try Jun.

Your best bet is to start at http://www.redhat.com/linux_what.phtml

RedHat produces a solid Linux system, that's probably the most friendly to
those new to linux.

LearningWorks has an interface to OpenGL that works under Windows. It is
free.
I'm not sure if you can just strip out the interface to OpenGL but for your
purposes you may be able to use LearningWorks as is. Or you can always ask
if you can take the OpenGL --
http://learningworks.neometron.com/default.htm. For some reason I believe
that I read that it was available. Anyhow see below for some of the features
of LearningWorks:

LearningWorks is under active development. This release of LearningWorks was
released on July 31, 1997. It features:

The ability to start LearningWorks without loading a course. Once started,
you can use the Course Binder's Settings page to specify the names of the
course definition file, course directory, and user directory.

A new implementation of the LearningBook framework that greatly simplifies
the preparation of book sections and pages.

A completed set of Smalltalk programming tools that obey the
author-specified rules for class and method visibility.

A revised and extended set of documentation.
 The ability to create applications using 3D graphics for Windows 95 and NT
systems with OpenGL.

The ability to link to Open Community, a multicast communications framework
from Mitsubishi Electric ITA. Open Community runtime capability is available
NT 4.0 only. We use Open Community to link multiple team members for
chat-based communications and shared construction of virtual worlds.

New books. The Turtles book has been revived. This release also includes
books that show off the new simulation framework, 3D graphics, and Open
Community.

and more ....
