New full featured black holes for Celestia

[Harry]

My new Black Hole and its pulsar are available now, at the Motherlode. Go to this page :

There's no picture showing yet, however. Just look out for the name "Black Hole 3".

BTW, it may be easier to simply link to the details-page:

Apparently, my version 2 of the black hole with a pulsar is already available on the Motherlode. Thanks guys !

If you downloaded the first version (without accretion disks around the pulsar), then you should erase that addon and download the new version, now available.

[Cham]

I made a fourth black hole, probably my last one : the "Black Pit". This time, I'll wait a little (few days) before uploading it to the Motherlode, just to be sure that this version is okay. This time, it's a lonely generic black hole (without any companion), which may be placed anywhere in the Celestia universe (within the 16k LY limit).

I worked harder on the jets, and I think they are pretty while in motion in Celestia.

Here's a picture of that puppy, with a used Q-tip through the ...

Cham, I'm very happy to finally be able to enjoy your work. You're very talented.

The jets look quite smooth now on the screenshot. And I like this thin bright inner core at the lower end, and the faint third cone.

Thanks very much for these new add-ons. They make using Celestia even more of a pleasure than it had been.

I'd like to raise a point however. In your original black hole (Ogre) the accretion disk could be seen to cover the jet that was further away. In your newest black holes and the pulsar the jets never are covered by the accretion disks. This doesn't seem to be quite right. Since you were able to cover the distant jets in your original black hole, would it be possibe to do the same in your newer add-ons?

Again thanks for the magnificant add-ons.

[Cham]

I'm not sure to undertand what you mean by covering the jets. Can you elaborate ? Maybe a picture could help.

[HJS]

Sorry I can't post a picture, but perhaps I can clarify with some text.

Say you are above the accretion disk, one of the jets is coming towards you above the accretion disk, the other jet is below the accretion disk and is directed away from you. The jet directed away from you should be partly covered by the accretion disk.

In the earlier version of the black hole that you created the accretion disk did cover, or partlly cover, the jet that was directed away from the viewer. In your newer black hole and pulsar, the accretion disk does not partly cover the jet which is going into the distance.

You can see this most clearly by placing yourself directly above the accretion disk, looking down the throat of the jet coming towards you. Then move the jet slightly, so that you are not looking down its throat. You will see in the newer version of your black holes and pulsar that the jet below the accretion disk is not partly covered by the accretion disk. All parts of the jets always appear to be above the disk. Perspective requires that the accretion disk should cover or partly cover the jet below the disk.

I hope this is now clear.

[Cham]

What you are describing is a limitation of Celestia. It does not manage depth very well within the models. Actually, I builded the black holes jets exactly the same way, in all versions. Only the textures changed. You should experiment the same problem as you described in all versions, but the scale may change a bit, as the black holes and their accretion disks do not have the same size, from a version to another. There's not much I can do here, sadly.

[Cham]

I have uploaded my fourth and probably last black hole to the Motherlode : the "Black Pit". It should be available in the next few days.

Here are some pictures that I've found on the web, which may help interpreting my addons :

[matt]

uhh.. i think its been long enough for the last black hole to b uploaded? is it just me or is it not on the motherlode?

[Cham]

I uploaded it last week ! It's still not there yet. The guys may be sleepin' at the wheel for the moment, I guess.

[Cham]

Finally, the "Black Pit" is now available at the Motherlode. Just go there :

HOLY

this one is just fabulous!

one question though, well two.. when i have all my orbits display there is a orbit for plasma.. is it supposed to turn?

and its not sucking any stars up as the preview pictures that you put up~ i was really looking foward that...

but it really is the best one u made so far

[Cham]

I want to do something like that :

[Cham]

I just began a new black hole project. I want to try to reproduce the picture shown in my previous post. Geez I like this one !

So below is a picture of the preliminary version. It is far from finished. There are many constraints in Celestia, about illumination on a mesh. So I'm not sure this one will be great. I'm not satisfied of the star appearence yet, because using a mesh for a star removes its atmosphere, %$#@&?*

I'll add a lot of solar flares on this one.

[maxim]

Well, nice.

But would you think that star matter is /spiralling/ into the holes aggregation disc?
And, as the star is rotating too, wouldn't there be at least a small (ahem) 'deggregation' disc around it?
Is there some knowledge available about interdependence between amount of star deformation, intense of matter flow and distance to the black hole?

Maybe a star so close to a black wouldn't have a significant atmosphere, as it would be the first thing attracted to the black hole.

[selden]

Don't forget that a star is a ball of gas.
As soon as you strip off the top level, the next lower level expands to take its place. This process is what Cham is trying to illustrate.

Hi,

Well I have just download Cham?€™s balck pit, and to know more about this fabulous add-on (tx Cham for this nice work) I have a look in the forum searching the concerned posts?€¦ (and more and more I realize how passionate are people here; it?€™s quite impressive?€¦)

Ok I meet those images on star being suctioned by the black hole and I must say they seems to me a little too ?€?artistic?€
