Yes Geoff, I would be interested in having a look at your macro, though I'm
not sure if I'll be able to understand it (my concentration is very poor).
Please either post it on the server, or mail it to me direct.
Thanks,

That's a good point Matt... I was wondering what these glows were reminding
me of, and it is Bladerunner.
Actually, somebody posted some code a while ago that reads in a bitmap
image, and rebuilds that image as an array of objects, each taking their
colour from the bitmap (I forget what the technique is called). I wonder if
this could be applied to an array of glows.. It would look fantastic if a
sequence of images were used as a source... like those huge video
billboards!

You've got me thinking now: Can of Coke, Pretty girls face, A company logo,
Something in Chinese then back to the Coke again.
Of course the streets would have to be wet with rain, and I could use
my trafficlights macro, and have traffic going past etc.

Xplo Eristotle also suggested something like this in my
"Fibonacci Stones" thread:
news://news.povray.org/39B5728A.54AE8936%40unforgettable.com
In my "Fibonacci Mosaics" thread:
news://news.povray.org/39B65D7C.9BE96D79%40online.no
the colouring of the blobs in these images are done
according to the colours in another image.
I can post the code for it. (But you would probably
want to do it the Mega-POV way :)

Somebody has actually done this before...use eval_pigment() to get the
color of an image_map at the position of each glow.

I don't know what you intend...this is exactly what #while loops were
created for, the other ways would be recursing macros(unnecesarily
inefficient, limited, and slow for just making a straight line), and
doing it by hand. #while loops are the best way to do it.

Nah, #for loops are ;)

That might have been me and the POV glow logo thing I did. The code is
still in p.b.s-f under 'Glow Logo zip' or something similar. But! I did it
in a very kludgy fashion that I wouldn't recommend you repeating. Me no
code demon either...
Bye.

How can #for loops be the best way to do things if you have to write the
patch first? :-)
I agree that they would be a good idea, and if they did exist, they
would be the best way to do it...
