Hey all!

I know the rand()-Stream ist just pseudo-random, not purely random. I 
use the same seed-Value, I get the same order of random-values between 0 
and 1, so far, so good.

What's with different OS'? I've got a WinXP-PC and recently also got a 
MacBook Pro (Intel Based). Since POV-Ray doesn't run natively on 
Intel-Based MacBooks (yet), I'm using MegaPOV to have something running 
there. ;-) Of course, since it's MegaPOV, the random-stream might be 
different again, but if/once the Intel-Based POV-Ray for Mac gets 
released, will the streams be identical?

You may argue that this question is purely scientific, when I use random 
streams, I'm looking for random-input, so asking how determined it is 
might be kinda stupid... Anyways, I figured I'd just ask. Gotta keep 
this random-stuff in mind when designing/writing my next images.

Point is: Once there's a new POV-Ray, or you switch to a different OS, 
the image might change, and when it's about re-rendering the same 
image... I might have to implement my own, SDL-based random thingy, 
that'd be a trick to be sure the stuff I want random ("but not really 
random") is more or less determined...

Ah, sorry, I'm beginning to babble, I'll stop here. Back to the 
question: How determined are the random-streams when talking cross-OS?

Regards,
Tim
