/*
|
|
* Fonction
|
|
* ~~~~~~~~
|
|
* Gestion des textures sous OpenGL
|
|
*
|
|
*
|
|
* Notes
|
|
* ~~~~~
|
|
* Les textures sont toujours initialisee avec des parametres par defaut
|
|
* texture 1D: WRAP_S = CLAMP
|
|
* MAG_FILTER = NEAREST
|
|
* generation de texture automatique en OBJECT_LINEAR
|
|
* rendu avec DECAL
|
|
*
|
|
* texture 2D: WRAP_S/T = REPEAT
|
|
* MAG/MIN_FILTER = LINEAR
|
|
* generation de texture automatique en OBJECT_LINEAR
|
|
* rendu avec MODULATE
|
|
*
|
|
* texture 2D MipMap: WRAP_S/T = REPEAT
|
|
* MAG_FILTER = LINEAR
|
|
* MIN_FILTER = LINEAR_MIPMAP_NEAREST
|
|
* generation de texture automatique en OBJECT_LINEAR
|
|
* rendu avec MODULATE
|
|
*
|
|
*
|
|
* Attention:
|
|
* ~~~~~~~~~~~
|
|
* Ce package a ete teste sur SGI, OSF, SUN, HP et WNT.

* Historique des modifications
|
|
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
* 22-05-97: PCT ; creation
|
|
* 01-08-97: PCT ; suppression InitializeTextureBox()
|
|
* 05-08-97: FMN ; ajout GetTextureData...
|
|
* 19-06-98: FMN ; Portage Optimizer (C++)
|
|
