Sorry, I wrote "jpg" instead of "mpg" before (cancelled that post too).
I decided it best to cancel the larger resolution version of this since I
messed it up so badly. I put a corrected, and Sun texture-changed, 512*320
res. at my animations page although
http://members.aol.com/chimerasgrafi/sp0.mpg is the direct URL.
Thanks for the comments again.
P.S. if glows were able to use patterns like media does wouldn't that be
great? Of course it would. hint-hint

You know, I was looking at this image again, and I'm not sure the flash when
the panels separate is right. I mean, it's basically claiming that the
flash is brighter than the sun (or on the same order of magnitude, since
otherwise it would be subsumed in the sun image) Now, that can't be right.
But it is cool looking.

Aw gee, I just knew someone was going to see it that way sooner or later :-(
While making it I was convincing myself that the gas would turn into a sort
of ionized plasma (burning?) instantly on contact with the nearby region of
the Sun. Not in itself much, but considering the closer proximity to the
viewer perhaps it would appear bright. Kind of like arc welding in
daylight. I know it looks a lot like a propulsive pulse maybe. It's only
supposed to be the coolant between the shell and probe.
| But it is cool looking.
Not hot? :-) I know I'm going to have to come up with much more to this in
order for it to be worthwhile, as always. Hopefully I won't ruin it as I go
along.

Actually, I thought of something. It may not itself be that bright, but the
light from the sun reflecting off it could be quite bright in itself. Not
sure how to convey that (maybe a sharp shadow from the segments? Too close
to the sun for that probably)
I still like it a lot. And I really like your sun. The media is gorgous.

Arg! A shadowy place behind it, you are so right. It's 'glow' though, not media.
Well guess I
can put a negative glow on the shadow side but it certainly won't be like any typical
shadow. No
reaction to the light from the Sun (I guess not).
| I still like it a lot. And I really like your sun. The media is gorgous.
And thanks a lot. Can't recall if I posted it before, could if I haven't already.
I'll check into
that.

Erm, what is "liquid gas"? :-)
You could use a refrigerator laser, like Sundiver...

I need to read this group more often...
I am planning to allow pigments to be used. This is more flexible, since
you will be able to alter colors, not just brightness, and you can use
different color_maps, transformations, etc.
The subject you chose is surprisingly similar to that of an image I just
posted recently in povray.binaries.images...except my image was of a
manned ship in the chromosphere of the sun.

Very cold kind. Not a gas anymore, but hey, normally it would be gaseous :-)
Seen that, and I could ask what a refrigerator laser is. Must be a ionization
neutralizing beam.

That close to the sun, the normal state for *anything* is a gas. :-)
Actually, an ablative solid starting at the same temperature should be
able to dispose of more heat energy than liquid hydrogen or nitrogen, be
a lot less bulky, and a lot easier to handle...

I don't know what you mean by an "ionization neutralization beam".
The basic idea is to pump the heat that leaks into the ship/probe in a
small area to make it temporarily hotter than the plasma surrounding the
ship, and use a high power laser to dispose of it...in David Brin's
book, a powerful X-ray laser was used on the Sundiver, and a
communications laser on the earlier Project Icarus unmanned probes. As
long as there was power(and there's plenty of that in the chromosphere),
the probe could just float around, using the laser as propulsion and
cooling.
I don't know the details, but I remember hearing about similar research
with lasers, and since David Brin has a doctorate in astrophysics and
has been a NASA consultant and physics professor, he has probably knows
what he is talking about. :-)

Makes two of us. I thought it might have been designed to nullify the
radiation in some way thereby making the hot plasma cooler. Wouldn't make much
sense anyhow because all sides would need to be done likewise. I didn't know
it was also a propulsion of sorts.
