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...
