I'd be pleased if I could look at it..

Hmm, I think I know what you mean, but the task of adding burst towards the glowwing
points would be a pretty mean time consumer... I think it'd be in O(n^3) or something
like
that...

Let me see... There would be approx 10*amount of points, that's linear, and then a
rotate
and fade... No, O(n^2) is more like it..

Yes, It was a help, i was kinda stuck in my thoughts... 
Anyone want source, ask :-)

Attached you will find a small image that shows my own feeble
attempts at making fireworks. The source is your for the asking.
Unlike the propeller headed math whizzes, that hang out around
here, my version is a brute force proceedural approach. It may
not be elegant but it does have it's advantages ( I understand
my own code).

Hey, that looks pretty good. Think of making this into a lens flare?

I hadn't really thought about lens flares. The anti aliasing
really threw me for a loop. It wiped out a lot of the reflected
firework light on the water. Had to add some cheater light sources
to get the reflected colors seen in this image. AA also wipes out
star fields. Anybody else notice this ?

  I hadn't intended on developing this any as I only pulled the
code out for Spider and polished it up a bit. Well I added the
water, positioned all of the fireworks, reformatted all of the
code, added the skyline, optimized the rotations, added extra
colors, corrected some non-fatal syntax errors, and resized all
of the individual objects that make up the fireworks. Other than
that I just located the aforementioned code so I could polish it
up a bit for Spider. That is if he even wants it.

 As far as modeling goes right now I'm working on trying to
get something ready for my first entry to the i.r.t.c..
I would like to win me some of the there commercial modeling
stuff they give away to the winners. Yea right !

If anybody wants the source for this mess let me know.

Propeller headed??  Not that I am a math wiz, but I doubt too many
people walk around with propeller beenies anymore...I think a more up to
date term should be used, perhaps just Card Carrying Math Wizzes would
be better title...?  BTW I like your fireworks, but not so much the
skyline... but that is just me...

yes, I've noticed and raged about it.... to no avail..

Yes, her really wants it..
I must say that your result is far better than my petty little test..

>>I'll be waiting... But, why the 5th ???

I think this may be an English thing. All stemmed from a plot hundreds
of years ago to burn down the houses of parliment and kill the king. I
forget now. On the 5th Nov. is fireworks night, when we build huge
bonfires and put 'Guys' on top of them. These 'Guys', as in Guy Fawkes
are meant to be a representation of the bloke who's 'evil' plan it was.

I suppose the English don't put much stock in the American
independance day celebration do they ? Nope suppose not.
The Chinese people use kilo tons of explosives each year to
celebrate the new year and the Mexican people use them for
their own Cinco de Mayo celebrations. Do the French use
fireworks on Bastille day ? I've seen several photos of
fireworks with the Eiffel Tower in the picture.

Nice fireworks, but I don't get it.  What fun is code you can understand?  Gotta
go wind my propellor.

Hey! I'm proud to be a propeller head! :)

In my circle that means you like airplanes. ;)
