Revising for the <a href="http://www.dcs.gla.ac.uk/courses/teaching/level3/modules/gmm3.html">Graphics & Multimedia</a> (GMM) exam can be a serious pain.
Thankfully, <a href="http://www.mrry.co.uk/">Derek</a> is on hand with a useful memory aid.
|Derek:||i have an mnemonic for a part of gmm, that you might find useful|
|Neil:||share with the class|
|Derek:||you know when you're looking at fishnet porn on the interweb?|
|Matt:||I'm going to say "sure" in order to move this on.|
|Derek:||and you click to see the full-size picture, but the browser does that shitty thing of resizing it to fit?|
|Derek:||and you look at her legs, and something seems wrong?|
|Derek:||that's the nyquist sampling limit.|
|Derek:||either that, or you're looking at cripple porn. and that's not my bag|
|Matt:||so the take-home part of that is: resized-to-fit fishnet porn leg distortion = nyquist sampling limit|
|Derek:||you're seeing spurious low spatial frequencies|
|Derek:||due to aliasing|
|Derek:||it's a pain|
|Derek:||i can't look at it now without thinking of gmm :/|
|Matt:||it must ladder those fishnets something awful too.|
