Subject: HALVE the time to render!

Okay, now that I have your attention ...:-)

Yesterday I downloaded an archive of replacement maths libraries from my
local bbs, I guess they were initially sourced from AMINET.

The files name is: (or similar)

It is a shareware product, but has not been crippled. From, my initial tests
lastnight it is *WELL* worth the money ($20US).

Savings in render time vary on image content. I'm using IMAGINE fp version
on a a4000/40, but there are libraries for 68882/1 also.

The 040 math libraries make calls DIRECTLY to the FPU in the 040, no overhead 
in going thru the 68040.library and exception.


Some stats:

old time			new time

comet 2 project, frame 321, 640x400, trace.

1h20m				0H25m
Yes, thats 1 hour 20 m to 25 minutes!


several other experimental projects I have.

2m14s				1m04s

35m13				17m23

11m26s				7m31

48m34				28m12


As you can see, some MAJOR time savings to be had, I still have a few tests
to carry out, but my initial impressions are that these libraries are well
worth installing, trialing, and registering.

Please, can other people  install these libraries and report to me their
impressions. (dont forget to reboot after installing them :-)
