GLSL Hacker<\/a> est dispo sur plusieurs plateformes dont OSX<\/b> (OpenGL 2.1 et OpenGL 3.2 au moment de l’\u00e9criture de ce post) et il est important de bien sp\u00e9cifier la version du GLSL utilis\u00e9 dans un shader. La sp\u00e9cification de la version se fait par la directive #version<\/tt> au d\u00e9but du code du shader. A partir d’OpenGL 3.3, la version du GLSL est logique et elle suit la version d’OpenGL. Mais avant c’est un peu le foutoir donc un petit tableau r\u00e9capitulatif n’est pas superflu:<\/p>\n
