Old Pictures from Celestia (locked)

[selden]

J.T.K.,

This thread is for pictures made with Celestia which are fun to look at. It doesn't matter if they're realistic or pure fantasy.

Another shot of Jupiter and Hera -- This time seen from Earth.
You can see Hera's huge, sharp shadow being cast on Jupiter.

What is the distance between the twice ?
I think that it's too short, no

Example : Io is at more 421,000 km and the moon is very volcanic because too near of Jupiter...
so less a M-class moon, even in sci-fy world it's not serious

Don't forget Jupiter is 5 times further from the sun than Earth, so Hera needs the heat.

293644.2907 Kilometers, with an orbital period of slightly more than 24 and a half hours.

For me, I think orbital periods under 24 hours generally tend to be inside the Roche limit, so I like to use that as a rule of thumb when placing large moons around gas giants.

And as I mentioned previously, I meticulously adjusted the orbits of the Galilean moons to make room for Hera.

No, I don't feel like ejecting Thebe. Jupiter has too few inner minor moons as it is.

Like the Orion.
Was Orion designed to use nuclear detonations for propulsion? Or am I thinking about Daedalus?

[selden]

Both spacecraft designs use nuclear explosions behind a pusher plate. Orion would have used larger fission pulse units for larger spacecraft designs. Daedelus would have used a stream of deuterium/helium-3 pellets.

Orion is the "a-bomb" putt - putt ship

and for the cost of a few tactical nuks you can put something like the USS Nimitz in orbit

in this case BIGGER and heaver IS BETTER

Titan encounter coming up on the 24'th


just after close approach and leaving



from before to after

Stunning images John... superb!

[John Van Vliet]

always the same subject , nothing new

that is quite impossible

this is orbit 169 and ONLY is for the time period
July 10 to August 12

the orbit that is STARTING today
so this is a NEW pass by Cassini of Titan .
like the Dione occultation of the star Spica on the 23'd

Remember this: viewtopic.php?f=15&t=16958 ?

Though I still don't know how to re-center the dang .xyzv's, I did take a screenie.

And yes, that is a level 12 VT with a physical tilesize of 4k.

The viewpoint is at my house. I didn't catch the real time sunset though.






Because I was sitting outside watching the real thing.

The ultimate in Virtual Textures.

This is the highest resolution my computer can handle in Celestia.

Level 12, 8k tilesize.

Anyone using larger tilesizes for level 12?

[John Van Vliet]

synthetic Heightmaps with craters is getting there

need to add MORE of them but a early result
Heightmap ONLY
using a normalmap from a 16 bit Heightmap

4k "bumpmap" HeightMap

[Tegmine]

So John, you just put down a bump/normal map and then color the sphere as your "texture"?

Here's some systems I'm working on...a system near Nunki, and a rework of the Tegmine system...a more sublime change of pace from the deluge of Star Trek stuff. (No offense...it's been all a bit too much of it. I would like to see what work others have done.)

[Tegmine]

It cannot be denied that their output, shall we say, borders on excessive. Again, no offense was intended or implied. I just would like to see other works...

-M-

[Tegmine]

I agree. Less debate of these matters and more pix!!!!!!

-M-

[Tegmine]

Nope. Just a small rocky world. Got the texture from here:

I got Thorvald's Saturn texture package from the Motherlode, which itself is nice, but I figured I'd try my favorite G'Micky Mouse magic tricks on it, and and I thought the results came out nice and pretty.

The clouds and rings were left alone, and doing so worked out beautifully!

[PlutonianEmpire]

Sorry but already seen

What do you mean "already seen"? Did someone else apply a normal map to it too?

Anyways, almost precisely a year ago, I posted this bug report, where it was discovered that moons of moons can't cast shadows on their parent object. Although, the other object orbiting the Barycenter, in this case, Belle Hades' second moon Tartarus, could still cast shadows.

Fast forward to this week. In preparation for a video to upload to YouTube, I used reference frames to re-center the default Earth into orbit around a fictitious gas giant. I wound up finding out that Earth failed to cast a shadow on the parent gas giant. Somehow, it dawned on me that the ability or inability to cast eclipse shadows can be transferred when re-centering objects using reference frames.

See where I'm getting at?

What I did was change Lethe's parent directory from Belle Hades to the barycenter/reference point itself, and then use a reference frame to re-center Lethe back to Belle Hades, and lo and behold, Lethe's eclipse shadows returned!

bh_eclipse3.jpg

Yes, the faint shadow of Lethe blocking the second sun is there too, immediately to the left of the more prominent shadow. Shortly after posting the screenshot elsewhere on the internet, I noticed I forgot to align Lethe's body axes with the new trick, so I copied the reference frame's properties to a bodyframe reference frame and it aligned perfectly, no heavy number crunching needed.

An alien space station around an alien world, somewhere in the Andromeda galaxy (the background stars are real celestia stars in M31)...
The planet texture is from Massimo (Fenerit).

Just to follow my request here
viewtopic.php?f=2&t=16960&start=15
for more and better Star Wars models, compatible with Celestia 1.6.1, here some shots of what is actually available in Motherlode.
I modified (a lot!) the ssc files only, in orer to combine 3 Star Destroyers with 25 Tie fighters around Totooine
Nextly I'll add the Rebels fleet.
Hope you'll like them.

Great
The planet is colored

Yes, as you see even in Star Wars universe there is some color.

BTW, and this time seriously, what the hell could be the need of colored ships in space?
To recognize if friends or foe?
Bye
