texture offset

Is there a way to add an offset to the mipmap picking algorithm?

I mean, while a textured polygon is rendering, a certain mipmap is picked using an algorithm. Is it possible to offset this “value”.

If you want to clamp lod levels (you know you want to), have a look this: http://oss.sgi.com/projects/ogl-sample/registry/SGIS/texture_lod.txt

Ouch, twenty seconds late

great! Too bad we don’t have control over the dimensions of the textures.

Is it possible to create any mipmap we want for example:

500 x 500
400 x 400300 x 300

and so on…

The texture rectangle from NV can do this or is it just for uploading non_power_of_2 textures for level 0?
