I try use Lumiere http://vst.ensm-douai.fr/ESUG2009Media/uploads/1/lumiereIWST-2.pdf for show a sample OpenGL window but don´t works. I dont know what i doing bad.What is needed for use OpenGL in Pharo? Is a stupid idea use OpenGL under Pharo for create 2d UIs ? My idea is use Lumiere for build UIs embedded in a morphic window, but with OpenGL widgets, buttons, textboxes etc s is a possible idea? I could for example use OpenGL external widgets libs for use in Lumiere? Will be fantastic do a UIBuilder using that. If Lumiere dont works for that exists another lib o posibility?
