Hi guys

A cosine surface done with k3dsurf, and my very first rendering with
radiosity (been around for years, o'course, I never got around to it until
yesterday).

In flights of fancy, a freon ocean on a small planet in a distant solar
system, with a twinned sun and moon.

Simple planes and a standard povray sky, with a Colefax galaxy and
lensflare.

Code in scene-files, if anybody's interested.

Nice scene, Stefan!
Perhaps de clouds towards the horizon are somewhat weird. There seems to be
no perspective there...

Time to do also the Solaris ocean, don't you think so? Has been one of my
old old wishes....

Erm.. you are absolutely correct of course. Hmm...

Victory! Somebody has read Cosmos as well. A sea named Solaris...

Thanks for the comments.

err... I mean Solaris by Stanislaw Lem, with its sentient ocean. Is that the
one you mean? Or is that a different Solaris?

Cool scene Stefan.  Is it something about South Africa?  Gail Shaw once 
did a similar scene.  Maybe this one?

Where the liquid is only liquid at very cold temperature.

I knew which Solaris you meant! :) I've only read the novel (many years
ago); I'm yet to see the movie.  Trying to do POV images to illustrate some
of Lem's work could be a real challenge... I've read quite a few of his
short stories & several of his novels. I think I prefer the short stories,
although "The Futurological Congress" was pretty mind-blowing.

I'd like to see a POV render of a pair of Lem's robotic 'constructors'
engaged in one of their philosophical debates.

I read another wonderful SF novel a couple of years ago that had a sentient
ocean as one of its protagonists. The name escapes me ATM, but it was a
humourous, slightly cyberpunk, romp around the galaxy, containing all sorts
of neat goodies.

This novel had another interesting liquid life-form, which could be fun to
render. In its native state it just sits there looking like a beautiful
glowing blue pool, but when a human or other sentient entity touches the
liquid, they begin to have a telepathic experience. If they allow
themselves to go with this experience, the liquid will merge with them
symbiotically, giving the person an extended lifespan, permanent telepathic
& telekinetic ability, as well as the ability to pass the symbiote on to
others. Encountering this liquid life-form caused great change & division
in the human race!

Wow! I wish my first radiosity pic looked this good, Stefan. Well done!

Is Freon really blue in bulk? Anyway, it looks nice and it does look like a
low density liquid to my untrained eyes. :)

I would expect a planet with a Freon ocean to have *very* severe rainstorms,
as the atmosphere attempts to condense at nightfall. :) E.E 'Doc' Smith
wrote about a planet with a hydrosphere like that, where they had 40 feet
of rain every night.

I saw the movie which was a bit naff IMHO. On the Cosmos LP (can you
remember those?!) there was a song called "A sea named Solaris" which I
thought you were referring to. I should actually have said "listened
Cosmos".

The movie is confusing and a bit of a disappointment. But then, I may have
below-average intelligence and bad taste...!

Hmm - sounds like an Alien to me! :)

Thanks! Sometimes, this hobby feels like cheating - you rustle something up,
render it and BAM! It looks nice (most of the time...) You just never know
how it is going to come out - THAT is why I raytrace. Answer undefined!

No idea - freon should only be liquid at quite high pressure and thus most
likely high temperature as well (sucking my thumb a bit here - not a
scientist, me). Maybe it will be blue? Who knows. I made it blue
deliberately to subconciously trigger "ocean" in the viewers mind...
Ommmmm......

I really don't know - IMHO at human-livable pressures and temperatures freon
is a gas, only coalescing at "human-relative" very high pressures. I would
expect a planet with naturally ocurring freon oceans to have quite a high
gravity as well, and maybe be as big (or bigger than) Jupiter, for example.
This might also imply a very hot planet (guessing here) and an absolutely
lethal environment for an unprotected human. Percipitation seems highly
unlikely, since that is drivent by waxing and waning solar energy (school
geography is LONG ago) and not variations in ambient gas pressures...

But anyway, thanks for the compliment and looking at my pic.

Kind regards,
