Hello.
I've not spent many hours working on this, but here is a small image, showing how it
is..
I'd appreciate some response here, on how to make this look better... Does anyone have
a
source to share ???

oh, it's a PNG. 
The filesize is 1k larger in the PNG compared to JPEG, but the quality is far better.
The fireworks got a "blur" effect that made it all look horrible in a JPEG.

Good start !
Nice trailers ...
Need more density of the fire works - seems thin.
The haze should be up aroung the fire works and less towards the ground.

I have some source around here somewhere for some f'works I did once.
If I find it I'll send it your way.

Spider,

Damn it. I'm working on one of these right now. Damn. Damn. Looks kinda
similar to yours except mine is looking at a town on the horizon on Nov.
5th. I'll post when I'm done.

Add me to the list of firework makers too. Not surprised Ken had done
something like this though <chuckle>.
I made a basic program fireworks animation a decade ago and a couple
years ago did a POV-Ray one. Got the script here someplace, could be
archived away, but will look. I think it may be from something someone
else did, like a Colefax spray.inc example maybe. Don't remember.
Comment: maybe not that sparse, but looks so caused by lack of motion.
Which come to think of it, why is there firework burn at every point
along the paths, yet not in the bursts? This wouldn't cover for a
time-exposure photo unless the bursts were appearing only at an instant
of ignition after already being dispersed.
Oh well, you asked for a thought on it, or was it for some real help?

Thankya... It's a rather simple macro, placing spheres and rotating around the y
axis..

> Need more density of the fire works - seems thin.
Yes, I agree.. I'll add smoe more points there.

> The haze should be up aroung the fire works and less towards the ground.
That shouldn't be to difficult.... Right now it's static..

I'll be waiting... But, why the 5th ???
As for this, I only added a sky_sphere while testing.. I think I'll add some more
later...
But, this is only a test scene ;-)

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..

> Oh well, you asked for a thought on it, or was it for some real help?
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...

I must say that your result is far better than my petty little test..

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.

Yeah, antialiasing would be greatly improved upon if it could be limited
to specified, or excluded from certain parts of a scene.
The amount of depth, +R3 default, matters a great deal as many already
know. More improves singular point "seeing", yet less depth allows for
less smudging.
Any votes for selective antialiasing? Or has this vote been balloted
before...?

A new keyword to an object , antialias off, or no_antialias would fit
nice.

Or maybe set it to antialias everywhere but the edges (good for images with

This was three years ago but as we now know this is because colors
are clipped before aa and also DOF calculations. They don't need to
be clipped. 100% is not the maximum incoming light intensity in the
virtual povray camera. The 100% limit is only in the virtual film
which records the incoming light.
