Guile OpenGL

Guile OpenGL

[Javier Sancho]

Hi all,

I'm looking for a Guile module for OpenGL. I found GuileGL [1] and 
guile-gl [2], but both seem abandoned, and Guile website says Mesa 
interface is pending.

For the moment, I've started a new wrapper for GL using smobs so we can 
play with garbage collection too.

Greetings.

Guile has a wrapper to the ultra-hip clutter library :) See here:

	http://www.gnu.org/software/guile-gnome/

If you are interested and need help for installing, let me know...

Cheers,
David

Thanks David, but I'm working on a little extension for making games
and Clutter seems done for GUI.

I've mapped some SDL and GL functions, but now the project is growing
and I think the best idea is to separate the access to these libraries
into wrappers or adopt existing ones.

So, if there isn't wrapper for SDL and GL, I'll create guile-sdl and
guile-gl modules for Guile community and me (well, I'll try it).

Cheers.

But it uses cogl, which we still lack from guile. It would be nice if you take a
quick look at it and if it suites your needs, rather helping with the cogl wrapper.

I am not the developer of guile-gnome, and never wrapped any lib yet, I am a
guile-gnome guile-clutter user ... but i think you probably want, even if you
wrap opengl, to take a look at the doc on how to write a wrapper: you'll find them
if you git clone guile-gnome [and guile-clutter for your coding curiosity maybe], or
browse the git repo ...

I think there is an SDL recently updated but not sure.

try to see if cogl could do the work before, and if not, good luck: wrapping opengl
is a huge work!

	the doc i pointed are [too] old, I am sorry.

You'd want to read HACKING which has been updated recently.

Cheers,

I didn't know cogl. I've to play with this a little, integration
between OpenGL and OpenGL ES is very tempting.

I'll do it.

SDL team is working on a new version (2.0), but 1.2 is still the stable current.

Well, basically I only need time... so step by step.

Thank you so much, David.

http://www.nongnu.org/guile-sdl/ is still maintained, and should work on
2.0 [0]. It would be nice if any work on sdl bindings is either
coordinated with ttn, with a view to be included in the existing
guile-sdl, or if it were at the very least compatible.

0. It used to be necessary to make a small tweak, I forget if this is
still the case.

Thanks Ian. I discovered guile-sdl yesterday, reading ttn on sgf utils
at guile-user list.

For the moment I'm working on opengl bindings. I want to use opengl
with sdl, so when guile-gl is ready, I'll test it with ttn guile-sdl.

Maybe next week I'll publish a very first version of (opengl gl).

Cheers.

Hi Javier,

If you haven't done anything yet, I started to work in the OpenGL
bindings a while ago. If you like it may be you can continue working
on that.

https://github.com/aconchillo/guile-gl

I also created a couple of python scripts to create the C and FFI
bindings template given a header file (under tools directory), you
might find them useful.

Best,

Aleix

Heya
lib wraper experts,

Please let's all do the same and not reinvent the wheel, rather get the doc/scripts
which exists better ...

Andy updated the 'HACKING' file on top level git tree of guile-gnome and/or
guile-clutter, which explains how to and how he did it, with an example... that's
how guile-clutter has just been wraped ...

Cheers,
David

Unfortunately, I am not an expert at all :-). Actually it was my first
try to wrap a library and I don't even remember how I started, but
certainly I didn't read the file you mention. May be I would have read
it if I knew it existed :-).

Thanks for the heads up!

Great job, Aleix!!

I'm working with Andy's templates, but his scripts are designed for
gnome libraries, so maybe I can use some pieces of your code.

As soon as I get something working, I'll share it.
