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. -- Javier Pimás Ciudad de Buenos Aires
