Here's some pics of Spirit inside of Gusev Crater.


I hacked the crater out of the 'Maadim Vallis' model on the Space Graphics site also using their 'm46 Texture'.The model of Spirit came from the Nasa version of Celestia.If you have an ssc with Spirit already you may want to edit it.You can find a zip of it here

This zip has all my Mars Volcano models also,but will only work in the latest versions of Celestia.Hope you like them,Jestr

Jestr,

I've only just managed to see your screenshots, which has made me download this straight away, and all I can say is......

SUPERB!

Top job

This is great, matches perfectly to my mars texture.
looks great from above.

Plust the extra modeling on the rover is very good to

I cant claim credit for the model of Spirit.It came from the Nasa Celestia install, though I think the textures were done by Dr Love ?.Just thought I'd let you know you can get a model of Olympus Mons at the same address as above I'm not sure about the scale though (heightwise).The model came from the Space Graphics site again and I tried to download it again to get the height right but couldnt find it.It looks about right,try it-it matches the m46 texture again.Jestr

Cheers for the Olympus Mons model as well Jestr.
Maybe you should announce the availability of this model in a seperate thread, so that more people will be aware of it ?

These models are really great, they are especially effective when viewing at sunrise and sunset.

TERRIER

PS
Imagine a model of Valles Marinaris
Did someone once ask for this ?

I have the model of Marineris from the Space Graphics site but it is difficult to get it to work in Celestia because it needs to be inside of Mars to match with the texture and causes problems -the sky disappears when you go inside of it.The only way I got it to work was by making the whole of Mars a model but then you cant use VTs.If you like I have it on my FTP site.It is a bit slow in Celestia and older mars textures though.Jestr

TERRIER, imagine a model of entire Mars when Mars Express 3d cartography will be released

Jestr, this is a wonderful work, thanks a lot.
Don't know exactly who have created the rover model: seems to me that Alan Federman had purposed a work-in-progress one and 'Dr Love' had submitted in the forum a corrected and textured one (and you another). Maybe the model in NASA pack must be a final version by A. Federman, yes?
I would like to know exactly who composed the *currently* findable model and textures (and where to find them now) to bring up to date my MER page (and to add recent pictures of Gusev, of course!) Jeam

Hi Jeam you can get this 'MER' model from here
http://exp.arc.nasa.gov/downloads/celestia/models/
look for 'Mer.zip' as far as I know it was corrected and textured by Dr Love-see the post called 'New Mer and Viking models' or something like this.Hope this helps Jestr

Thank you for the address, Jestr, I had not seen it. I had carried out my page at the time of the thread that you quote -i had posted the screenshots by Dr Love- and had carried out pictures with the model that Dr. Love had pleasantly sent me; Alan Federman had not put it yet on line, this is why there was no link in my repertory. I will correct my page as soon as possible.
Do you work about the Opportunity landing site landscape, to complete the MER missions with probe, rovers and sites ? Jeam

Jeam,I have made a model of the Opportunity site from a 16k bump map using 'Bryce' and finished in '3ds Max' so I'm not sure if the scale is right and there is no obvious limit to the area concerned (not like the crater in Spirits case).Also it was more difficult to get it to match with the texture as it covers a larger area.If anyone wants it they can get it from the same place as 'Gusev' above.Look for 'Meridiani.zip'.Jestr

Silly Question:
Seems to me that crater 3d models run 'Over' the clouds texture...
What's the matter? Jeam

You're correct,I hadn't tried them with the clouds on but 'Mons' and 'Meridiani' do,when you go to the surface though the clouds are above you,at least with 'Opportunity',I dont know about 'Mons'-could it be a bounding box issue ?i tried bumping the cloud height up to just over 100k and it didnt seem to make any difference,-strange.Jestr

Very nice work,Jestr.It?s really fantastic to see Spirit inside Gusev and we can actually see a planet?s surface.

Is there anything special I need to do to get these addons to work? I copied the models to models/ and the textures to textures/medres/ and the ssc's to extras/, yet none of these surface models are working. I've tried olympus mons, gusev crater, and ascreaus mons, none of them show up. And yes, I'm running the latest version (1.3.1).

Is there anyway I can get additional info? Like, maybe it's not finding a file or something.

I too cannot find the models in celestia.
I downloaded the spirti/gusev zip and the olympus mons zip.
first I put the .ssc, models, and texture directorys into the extra folders
I started up celestia, went to mars, the hit enter and typed in "olympus", "spirit" and "gusev" nothing was found.
I then tried putting the ssc file into the data directory, and putting the model files into the main celestia models directory and the textures into the main clestia meres directory.
Restarted celestia and still got nothing.
I am using v.1.3.1 of celestia.
I also have virtual textures for mars and its normal map.
and turning clouds on and off made no difference.
I can see spacecraft around earth.

What can I do?

I looked at olympusmons.ssc:

"Olympus Mons" "Sol/Mars"
{
Class "spacecraft"
Mesh "olympusmons.3ds"
Radius 314

LongLat [226 18.65 -13]
Color [ 0 0 0 ]
Albedo 0.15
}

not a lot there, compared to the pathinder/sojourner ssc file, which had a lot more data such as eliptical orbit, period, semimajoral axis, mean longitude, and a bunch of other stuff.

were these addons meant for an earlier version of celestia?

The LongLat declaration is new with Celestia v1.3.2pre6 (or thereabouts).

Before it became available, a more complex method was necessary to ensure that models were properly positioned relative to the surface of a rotating body.

Note, however, that two declarations are missing from the SSC example that you show which still may be needed to properly orient the plane of the model with respect to the planetary surface: Orientation and RotationOffset.

See http://www.lepp.cornell.edu/~seb/celestia/hutchison/defined_locations-130.html for a description of the more complex positioning method, along with information for calculating Orientation and RotationOffset.

Yes I rotated the model to the correct orientation in 3ds Max so as to simplify the ssc,I couldnt see that anyone would want to use these models anywhere else,so assuming you have Celestia 1.3.2 pre 6 or later it should work fine.Jestr

After playing around, it seems you need the prerelease of 1.3.2. After installing pre8, it then displays. However, it doesn't come close to matching my Mars texture, and the objects are not correctly seated on the surface of the planet. If you position the camera correctly, you can see under it.

Yes theres not much you can do about seeing under it try altering the last number in the LongLat part of ssc (this is the height from the surface).The texture Ive used is the Space Graphics M46 texture (I changed the hue of mine slightly)so it should be a reasonable match with this,Jestr
