Okay, get your imaginations out and picture this small and fast animation to
be a vantage point near the Sun where a probe passes by.  The outer shell
separates with a puff of instantly ionized gas as the camera changes to
filter light from the Sun so as to see the solar flares better.
Just trying this idea out to see where it takes me.  Figuring I have to go
with quite a bit of artist license or it won't look any good.
TIA for viewing it.

That looks really impressive, how did you do the sun ?

maybe add some firing thrusters to the probe...

The whole movement (camera/probe) looks very pleasant, good work on that.

And please do a larger version too.

excellent work!, especially the flare on probe seperation, i think you might
be onto a winner with this one!

not sure if i like the way the sun changes tho....

and as chris requested - how about a bigger version :)

Very Cool!  It looks like the two outer shell halves decelerate after they are
blown from the probe.  They should maintain a constant velocity away from it.
On the other hand maybe they do, but the probe is moving away and getting
smaller so fast that its just an illusion.  Anyway, great work!

As everyone else has said, motion is very natural, but change in color of sun is
not well explained.

Done, but I did a major mistake when fooling with clock in the glow portion,
you'll see if you look at it.
The Sun is something I had done earlier in a animation going from Earth to
the Sun at incredible speed.  Well, pretending so.  It's basically a layer
cake of media in spherical density_map using different patterns for corona,
flares, surface and subsurface.  Not really much to it other than the
adjustments to get the right look.
I'm still planning it out far as how it would go.  Idea is for this probe to
get there fast with as little time as possible in the hostile environment.
Low profile, rotating, liquid gas insulation, etc.

You're easy to please, it does have it's problems... most of which are
because of me.
I flubbed up the glow expansion.  The idea is to have the camera iris close
or turn into a hydrogen alpha filter as it got more of it in view.  Maybe
never be realistic but I thought it was the only way to show it as both
intensely bright and have flares on the edge appear.
512 by 320 is now here.

Not an illusion, I wasn't sure I could use linear clock with clockmod.inc
(thanks yet again to Chris Colefax) but sure enough it can be, it's simply a
case of choosing other than the ones available.  Needed it to start with 0
at 2/3 clock, anyway I fixed that but messed with the glow expansion and it
now pauses.
Glad you liked.

Camera aperture closing or hydrogen alpha filter gradually applied or both,
think of it that way.  However it never will be realistic since I need it to
look theatrical instead.  I like to comply with reality, or try to if I can
but for one thing I couldn't be sure of it in this case.

Again, it is very cool, I just think you ought to keep the sun looking all the
time like it did at either the beginning or the end.  Either way, you'll fool us
non-astrophysicists. With a change, the little voice says, "of course that
violates physics/ optics of viewing."

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.

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.
