kao_chen a écritPetite question:
Comment puis je connaitre la version d'OpenGL (2.1/3.3/4.1) installé sur ma machine.
J'ai voulu installer un des benchmark d'Unigine
http://unigine.com/products/heaven/
Mais j'ai une erreur qui m'indique qu'il manque le support extension GL_ARB_map_buffer_range
Et si je me reporte à cette page il est indiqué que l'application nécessite OpenGL en version 3 minimum:
http://wiki.x.org/wiki/RadeonProgram
64 (19 November 2010) It crushes because: required extension GL_ARB_map_buffer_range is not supported. This benchmark needs OpenGL 3.x support.
Donc, comment puis je connaitre ma version OpenGL actuelle?
Est il possible de passer à une version supérieure? par compilation?
Ou alors, OpenGL est dans Mesa et Gallium, faut juste patienter que quelqu'un implémente l'extension?
glxinfo dans un terminal te donne plein d'infos y compris la version OpenGL. Je suis en ce moment sous arch et j'ai:
