Hello POVers!
Here is my work so far for my IRTC entry. It is still at an early state, but
comments will be welcome. The POV logo on the bottom right is just a try
for photons.
Btw, I started it last month (could not work much on it since), and I did
not copy s day's idea, though we have points in common.

I like it - I like the simple uncluttered style.
Apart from wondering what the white thing in the top left is, there
seems little to criticise with this image. You might get people saying
its not got enough fire but it's a nice image, and currently a good use
of the pov logo.

Don't worry it's a totally different style, yours is more fantasy based.
I will however be surprised if anyone does anything similar to mine :-)
(if I ever get it presentable).

Me again.
Thinking of a name for my scene I found something like "Ardent Bush on a
Lost Planet".
A strange-looking star rising and making an isolated bush ardent, in the
quietness of a clear sky and in the coldness of a snow desert. This is my
interpretation for this round, without any photo-realistic goal. I would
like my scene to be simple yet symbolic.
Regards

Thanks Verm for your reply. The thing on the top left is a star-cluster, a
bit like our Hercule's cluster. Obviously, I did not succeed much for this
object :( and I'll try someting else. One will find herafter a photo of the
actual Hercule's cluster.
My scene is still in an early state, and I will populate the ground and
perhaps the sky with a few (not too many) other 'organic' objects that
become ardent/burning by the effet of the star, bringing some kind of life
to those entities, but leaving inert things cold. My first idea for this is
to put an ice cristal on flame in place of the logo. Your opinion?

it seems to me as if the particles are placed evenly (homogenious?) in the
sphere. you're probably using the VRand_In_Sphere macro in rand.inc.
in any case i would recommend to raise the vectors to the power of two or
even a larger number. as the vectors in a sphere (with radius 1) are
shorter than one they get sort of blackhole warped towards the center. this
should look more like what you want it to look. higher exponents strengthen
the effect.
just my 2 cents

The cluster is done with emitting media and turbulenced spherical density,
controled by another spherical density. I think I just have to play with
the settings until I get a better effect (might be very sensitive).
Here is the code:
//
----------------------------------------------------------------------------
#declare CLUSTER_RADIUS = 6*SUN_RADIUS;
#declare COLOR = White;
#declare O_Cluster = sphere
{
0, 1
pigment {rgbt 1}
hollow
interior
{
media
{
emission 200*COLOR/CLUSTER_RADIUS // Small dense areas ==> 200
for lightness
samples 20
density
{
spherical
scale 5 warp {turbulence 1 omega 2} scale 1/5 // this makes
the stars
}
density
{
spherical
color_map {[0 rgb 0] [0.7 rgb 0.07] [0.8 rgb 0.6] [1 rgb 1]}
// This makes the thing look like a cluster
}
}
}
scale CLUSTER_RADIUS
translate SUN_DISTANCE*z
rotate -12*x - 17*y
}
//
----------------------------------------------------------------------------
For render time reasons, I used a blob for the stars rather than hundreds of
spheres.
Thanx for advise.

It is symbolic indeed. I like that touch.
However, even without wanting to be photo-realistic, maybe the sky around
the star should show its influence. I mean, the gradient now seems to come
from some sunlight below the horizon...

I agree with the strangeness of this atmospherical effect. Before the
current topic was known, I was experimenting atmosphere media for planetary
scenes. And once, I got this effect with highly directive scattering media
and found it interresting. The color is made by itself, no color_map...
With some other setting, it could be like an atomic explosion far away.
And when the topic "ICE & Fire" got to be known, I decided to re-use it. We
are on a strange planet, and the strange star produces strange effects. My
work on it now is to put 2 or 3 additional objects strangely affected by
the rise of the star: the tree becomes 'ardent' with an aura, I will
probably put an ice-cristal which comes to flames, and I'd like to put
something in the 'atmosphere'.
Regards
Bruno

Hmm... yes, I like that. I don't know why this makes me think of a
(probably?) nearly forgotten book: The House on the Borderland by William
Hope Hodgson. See for instance: http://eserver.org/fiction/borderland/
It does not relate to your scene really, but it describes some strange
atmospheres in relation with a strange sun. It is rather a scarry book in
fact.

Thanks for yor concern and interest. I have to work it further, and I'll
post he result as soon as I have something significant to show.
