OpenGL and scheme?

[Ketil Z Malde]

Hi

anyone aware of a Scheme with OpenGL bindings? Found some documentation
on the net that seemed to indicate this existed with Guile, but for the
life of me I couldn't find anything substantial.

Pointers, references or rumors welcome.

This did in fact exist for guile-iii, an old version of guile. But
maintainers changed, there were no openGL users, and it bitrotted.
There is SWIG, which claims to have basic guile support; its standard
test app is to generate OpenGL bindings for each of its languages. I
don't like the SWIG/scheme combination. You might look at G-Wrap, or
at revitalizing the old guile bindings. Unfortunately guile (and many
other schemes) use a stop-the-world approach to garbage collection, so
interactive apps may be subbject to periodic long pauses.

I don't know any schemes that support OpenGL anymore. Adding OpenGL
as an extension to guile should not be difficult. Please let the
people at http://www.red-bean.com/guile/ know if you do this...

Ivy is an extension to scm to drive Open Inventor on Irix. I suppose that's
a layer of abstraction too much for those who want direct OpenGL support.

I've got bindings for Scheme-to-C, GNU Common Lisp and Allegro Common Lisp.

There is a package for RScheme here:
http://www.erols.com/mlrilee/Prog.html

I haven't used it and the page says it is proof-of-concept. However,
since RScheme comes with a real-time garbage collector, and seems to
be a very nice Scheme implementation, it should be worth serious
consideration for this kind of application.

Hello all,

Robert noted that Ivy from the MIT Media lab supports Inventor, which
is layered on top of OpenGL. When I was writing Nintendo games
at Angel Studios, I had the good fortune to have a SGI Reality Engine
for my desktop machine (well, at least the monitor and keyboard
<grin>), and I installed Ivy. It was very cool! Inventor is available
on other platforms also for $$$, but if you use a SGI box, Ivy is
really worth a try.

There is a free clone of Inventor called Apprentice:

I've used Ivy with the real Inventor, and it was spiffy. I've never
tried Apprentice, but it's worth a look.
