Hang on a minute there... I don't recall mip-mapping stuff anyway...
Ah wait, there it is.... in a past paper. Is there a reference in the textbook anywhere to it (I think I might have a previous version of the textbook here with me, will have to check when I get back home and compare to the other book),,,
See you all on the dark side tomorrow afterwards. I have a feeling its going to be a stormy day...
