題目: Problème OpenGL
Bonsoir,

J'essaye d'utiliser freevp, un truc qui permet de visualiser des panos en
QTVR sous Linux. Mais je n'obtiens qu'une fenêtre toute blanche. Voici
ci-dessous le résultat de la commande. Une idée du problème ?

$ freepv-glx 6000x4000.mov
XF86VidModeExtension-Version 2.2
Got Doublebuffered Visual!
glX-Version 1.2
Depth 24
Congrats, you have Direct Rendering!
