graphics package wanted

[gate.ready.com!taurus.cs.nps.navy.mil!erickson]

Do you know of any graphics packages with Ada bindings that are higher level 
than X intrinsics?  Procedures like draw_line, draw_rect, fill_region, etc.,
but that don't require familiarity with X widgits.

Or, can you suggest an alternative approach that would support
creation of bitmaps that could be read by some existing graphics
software through a pipe or socket?

The problem comes up because I would like to have my data
structures students do some projects that have visible output,
such as animation of linked-list or tree balancing procedures.

I also think it would be an excellent way to motivate some basic
problem solving, in the style of Rich Pattis' Karel the Robot.

This was an easy problem to solve when I taught the data structures
course in Pascal (at least one of our Pascal compilers supported
Turtle graphics), but as I've come to realize, nothing is easy in Ada.

A package that runs on Sparcstations, PC's or Macs would be o.k.

I have used Motif and also GKS Ada bindings, but these are probaly overkills
for your needs.

Look at HeraInterface.  Complete GUI widget set (Motif look & feel)
along with window management and low level graphics primitives
such as draw-line, fill-region, draw_rect, etc...

Big win is it runs on both DOS & UNIX/X windows.  You simply
recompile your Ada application to run on either platform.
