This is not a finished picture at all, just a sample exercise to show off
the different glows' properties.

Some information on the picture and some thoughts on glow:

o  There are 100 glows in the images, all images were rendered 320x240 no
AA.
o  Glow types 2 & 3 color statements were increased 10 fold, due to their
limited interaction.
o  The radii used were complimentary to their visible glow.
o  There are obvious speed concerns.
o  I think each glow has its own usefulness.
o  I feel type 1 works best for this image; type 1 has a blobby/plasma feel
to it.
o  type 0 is close to type 1, but the glows act more individually [stars].
o  type 2 is fast and has a unique clumpiness, almost cloudy.
o  type 3 is a fast way to approximate the look of 0 & 1.



quick conversion from 0.3 to 0.3.1

glow { FLOAT_AMOUNT color VECTOR ... }
-- changes to --
glow { color FLOAT_AMOUNT*VECTOR ... }


Don't forget, I think 'turbulence' changed as well, and I'd also suggest
against using 'size' at all (it's hazardous to your sanity).

Also! Read the docs! Have fun! Experiment! These things animate wonderfully.

I'm not getting the new syntax, can you post a sample? I keep getting "float
expected, end of file found instead".

I think the *simplest* example would be:

glow { }

you should throw these in for good measure:

camera { location z*-10 }
box { 0,0 }

I believe 'glow { }' implies:

glow { color 1 location 0 type 0 size 1 }

An example of a 0.3->0.3.1 conversion would be:

glow { 2 color <.2,.3,.1> location <0,1,2> glow_type 0 }
--to--
glow { color <.4,.6,.2> location <0,1,2> type 0 }

You say it says "float expected"? Could you post the glow statement that
produces that? Oh, and make sure you're running the version you think you
are [check 'Help | About' or the console]. (I often have different versions
running at the same time and confuse myself regularly.)

I get a similar error "object or directive expected
but end of file found instead" if I don't put a box{0,0} after the
glows.... see my post in p.u.p.

    That fixes it, thanks.
