Some weeks ago I somehow stumbled into a really good site called the daily WTF… been perusing it a bit… and found out a link to a post which makes you think:

Remember folks it's time to stop crying about the old man who doesn't know
a bit because someday you will be the old man and
you will need to work to maintain your vices.

work to maintain your vices?!?!?!… where did I last hear of that?!?!?!

ps. yes, that’s an IRL+SCENING crosspost ;)

68060-optimised texture mapping – part 1 July 3, 2006

So, hanging out on the ADA forums, we came up with a conversation about 060-specific optimising, which is sort of like pentium-specific (U/V pipes of fame) optimising. 060 has pretty harsh rules for address generation delays, so there is ample of oportunity to try ingenious ways to reorder stuff as to get no half-cycles wasted… linky linky provided for your pleasure ;)
The only real limitation I can see for this mapper is that the loop count has to be less than 255, but then again I don’t believe in big polygons :P
