1 | /* |
| 2 | * Fonction |
| 3 | * ~~~~~~~~ |
| 4 | * Gestion des extensions sous OpenGL |
| 5 | * |
| 6 | * |
| 7 | * Attention: |
| 8 | * ~~~~~~~~~~~ |
| 9 | * Ce package a ete teste sur SGI, OSF, SUN, HP et WNT. |
| 10 | * |
| 11 | * Remarques: |
| 12 | * ~~~~~~~~~~~ |
| 13 | * Le InitExtensionGLX permet d'initialiser le display. Ceci est necessaire |
| 14 | * pour travailler sur les extensions de GLX. On ne peut appeler QueryExtensionGLX |
| 15 | * si on n'a pas fait cette manip. |
| 16 | * Par contre QueryExtension gere les extensions a GL, on n'a pas besoin du |
| 17 | * Display. |
| 18 | * |
| 19 | * Pour l'instant on ne gere pas les extensions a GLU et a WGL. |
| 20 | * |
