The Texture Object Extension

The Texture Object Extension

The texture object extension, EXT_texture_object, can improve the performance of programs that use multiple textures. It allows you to create as many textures as you need, and provides an efficient way to switch from one texture to another. This is similar to the texdef/texbind model of IRIS GL.

The extension also adds a new texture parameter, the priority, which you can use to tell the system which textures should have priority when it allocates hardware resources.
