Hi,

A few days ago, Rob Jenkins posts some OpenGL tips on IR :

> Texture memory management tips
> Use texture objects rather than textures in dlists

If I use 32 bits mimapped textures (file format) and 16 bits internal format,
what is the size used for this copy ?

1) 32 bits with level 0 only
2) 32 bits with all levels
3) 16 bits with level 0 only
4) 16 bits with all levels

Thanks.
