#SXP inner workins'

Hi Jonas,
We figured out exactly how SXP bump mapping works. Please scratch the request
for detailed technical information. Would you like a text file explaining the
spatial gradient function operation posted? It has to do with point
multidimensional gradent vectors evaluated across a spatial magnitude function.
Some routines, like the ONLY BUMP MAPPING SXP IN THE DEVELOPER'S KIT, confuse
the issue by fractalizing around the magnitude evaluation at all instantaneous
point calls…
As soon as we do up a manual, we plan to post routines that will replace the
simplistic morphing of the ripple and wave PXPs with time-based SXP control.
You'll like 'em ;-).

Yes please 🙂

Any chance of having a small source code example posted too?

Good Morning Jonas,
My, you're working early this glorious Sunday morning. I will write up a
little description of how the math works and post it here, and Audrey will
generate a very simple bump mapping example in SXP source code. We haven't
forgotten we need to get you the demonstration files for the KXP/IXP with
particles running hybridization failure as well. It's on the list.

Thanks Eric.

That's easy for you to say! :^) Watch out, you're starting to sound like a
computer nerd or something even worse! And don't start blaming Audrey for that
one! <bg>

Hiya –
Computer nerd, graphics geek, pocket-protector engineer, and dweeb
mathematician: I'm afraid I'm all of the above, with the paper to prove it…
Fortunately, it's people like us who really run everything.

It seems that the same people who were picked on in high school are the rich
and successful ones today, and for the same reasons!
Greg
>>high school….rich and successful ones today<<
Amen. It's all more than a little bit o' fun.

Wealthy software geeks suddenly become very attractive… 🙂 Why, even poor
ones do OK. In college, my tutoring skills in computer science seemed quite
attractive to the lead pom-pon girl at UW-Madison.

And now you're married and living happily ever after? :^) Great computer
story!
Greg Pyros
No, I didn't marry that one. As my old Polish adopted grandma used to say,
John, you are so handsome, the young ladies are going to love you, and you just
gather them all up in your arms all at once, and look at each one in turn, say
"no, I don't want you" until you've got one left…
So I suppose you have Greek grandma stories? 🙂

I was one of those guy's that would of picked on you. Since the first time I
touched a computer was just 4 years ago.
<<<It seems that the same people who were picked on in high school are the rich

If I was one of those guy's then I should be rich. I wish. I'm just as poor as
the next guy. I mostly do this for fun. Once I start making real money , then
it will be work.

Um, I think you mis-read the message – that was from Eric Peterson. I was one
of the guys on the football team, no-one picked on us! I was just a part-time
nerd back then, and in much better shape, too! <bg>

Oh I see a part-time computer junkie. I was on the bad mitten team.
Hey Greg I'm selling SDP'sSXP's on my own now if you know any one interested
please E-mail me.

Yea, I wasn't full time until around 1982 or so!

<G> I wish I could say I have that much experience in the C.G. world.
I just going on to 4 years.

You youngster, you! It wasn't quite C.G. at the beginning, but it sure helped
later on!

Hi, Greg!
I was thinking why word "mathematics" in English is plural when
in Russian it is singular: "matematika",
(with conclusions like: "for russians Math is undivided body of knowledge,
while here it is collection of separated disciplines…")
when suddenly I realized that "matematika" is a Greek word.
Not only Greeks gave a name to every worthy science (math, physics,
philosophy), they also got some very good representatives in each of them,
like Phales, Phifagor and Euclid.
BUT (what a strange thing) since then – NOTHING.
They do everything (create partnerships, give lectures at universities, even
plan some buildings), but no Math.
What a mysterios Phenomena ! (BTW, a Greek word too).
Any insights???

That's true.

Thanks Eric and Audry!!!
Thanks Eric and Audrey!!!
