I wanted to mention another thing to keep in mind that was not
mentioned. While more memory and more processor and faster disk access is
good, it can, in general[1] only speed things up linearly, while choosing
better algorithms can speed things up sometimes _much_ better than
linearly.
I always kringe when I read 'Yeah I just used bubble sort because
there will never be more than X[3] and it works great for that'. I read
this with sorting alpha polygons in a 3d engine. What happens when (since
3d hardware is moving so fast) they take their engine, crank up the polys
for a RivaTNT[2] or a VooDoo3 and their performance drops to nothing? Now
they have to dig around old code looking for performance bottlenecks,
checking drivers etc.
Back to writing a NURBS evaluator.

[1] I am sure there are pathelogical cases where this does not hold.
[2] Fast 3d card.
[3] Where x is in the set of positive integers (Z) and is less than 100.
Quicksort is easy to write :-) (and the partition does not have to be the
first item). - processors Adam Wiggins
