Hi, I've just tried on Archlinux with Squeak-3.11.3.2135 VM from pharo website and it works (not with Exupery VM). Laurent Laffont 2010/2/10 Javier Pimás <elpochodelagente@gmail.com>
Fernando, thanks for the tips. I read about lumiere before, but I'm not looking for a complete 3d framework, just the opengl wrappers to do some experiments. A complete framework would be too much for what I want to try (hw acelerated 2d animations). Anyway, your pdf gave me a better idea of the status of all the available projects.
As of Croquet, yes, someone decoupled the OpenGL part (which is the same I tested yesterday and depends on Ballon3D). I finally was able to load it in pharo! If anyone is interested here are the steps:
Take a pharo image (mine had FFI and VMMaker already loaded, I don't know if they were needed at all)
In monticello add squeaksource.com/Balloon3D. Open it and load just this packages in order: Balloon3D-constants, Balloon3D-kernel, Balloon3D-math.
Now add squeaksource.com/OpenGL and load it.
That's all to load it, to try it, doit this code, and when you get errors change occurrences of Smalltalk to SmalltalkImage current.
ogl := OpenGL newIn: (0@0 extent: 300@300). green := 1. canvas := OGLCanvas new initialize: ogl. fade:= 0.
1000 timesRepeat: [ ogl glClearColor:0 with: fade with: 0 with: 1. ogl glClear: 16r4000. ogl swapBuffers. fade := fade + 0.001. ].
fade := 0.
I think the best way would be to use AlienOpenGL, which is the future, but for that I'll have to wait alien support in linux.
Regards, Javier.

Hola Javier, on top of AlienOpenGL , which is just an interface to OpenGL, i've built a 3d framework with better abstractions called Lumiere. ( http://www.inf.usi.ch/phd/olivero/LumierePage.html (A little bit outdated...i've added a couple of more things recently..)
In this paper that we presented at the last ESUG/IWST 09 , with also did brief survey of OpenGL in smalltalk. ( www.esug.org/data/ESUG2009/IWST/iwst09_submission_6.pd)
If there's a plugin for AlienFFI for Linux i'm not sure. But have you tried the FFI binding of OGL of Croquet? That one works in Linux. Look in squeaksource, because i remember someone decoupled the OGL wrapper from Croquet and put it there.
I dont know if June ( for visual works) works in linux, but you could take a look of it.
Saludos, Fernando

Hi, I've been browsing the different ways to use OpenGL in pharo and squeak. Here is a log of the results:
1 - Baloon3D - It looks like a layer on which squeaksource.com/OpenGLstands, so to use opengl you load balloon3d, then opengl and if you have the Balloon3dPlugin available then you can use OpenGL. This seems to include code dated from 2007/before. It loads fine in Squeak but in pharo I get many errors (load balloon3d-all in pharo1.0 rc2).
2 - GLMorphic - It uses FFI, so no plugin is needed, but it seems to be programmed only for windows, and I'm working in linux now.
3 - AlienOpenGL - It uses the new Alien FFI, which is only available in Mac platform.
So, the question is: is there any way to play with OpenGL in pharo on linux platform ?
Regards, Javier.
