Hi All,

Thanks to the folks at the Motherlode, Nasa/JPL/ASU, and of course John
van Vliet the Vallesmarineris virtual texture is now available. It's got
levels 5 and 6 for now. Level 7 will be uploaded in a week or two if
everything goes right. The files are in png format. Here are some screenshots. The last 4 are level7 shots.





















I also seen that the 1st update to the model files called Grand Canyon
of Mars is in my folder on the motherlode but not the main page. This was
by my request because I have another update ready which is a fix for the
northern edge of the model. I'll be uploading that soon so anyone wishing to download the update should wait a while longer. The current one has a virtual 4k version of the texture shown above. Difference being that it uses MDIM 2.1 background. It also is closer to 1x exageration.

In the future I will be doing a full Planet VT of Mars with MGS-MOC and MDIM 2.1 data. This is what I will be basing my model textures on for now.

Hope you all like it.
Edit:Any comments, pro or con, would be appreciated.

Very nice, Cartrite.
Can you please give us the downloads dimensions?

Oh yes, Mars is the preferred object in my public shows, so this VT is very appreciated, thank you for all your efforts.
Bye soon

Hi ANDREA

Can you please give us the downloads dimensions? Wink

Dimensions?

Do you mean level 5 14 mb? level 6 52 mb?
The level 7 folder is about 180 mb total. In 2 parts 7a=99 7b=80.

If you mean the full planet vt, the data sets are 256 pixels/degree which will give me a scaled down 64k. There seems to be some talk about Celestia accepting different sized textures in the near future, and that may mean that I will not have to scale down? So I will leave them at the original size. The same goes for BMNG july which I will also start soon.

Appericiate your interest.

Yes, I was asking for this, thank you.

I hope that Celestia improvement to unfixed texture dimensions will be in the next future, so I'll wait for, patiently.
Meanwhile, my best compliments for your work.

Thank you cartrite !
I like the color of the Vallesmarineris and I want to know if it is possible to put the same color on the complete map of Mars, it could be very beautiful

The color is NOT of my doing. This file was produced by NASA/JPL/ASU and all I did was the mechanical work to get it to work in Celestia. That way a Hi res texture of Mars can now be seen in Celestia by those who havn't the time or skill to do it themselves. I wish I new how to color a Black and White texture like that. I am starting a full planet vt from black and white data and will be experimenting with coloring it. If I come up with something I'll post it.

Thanks for this info.

For what it's worth, netpbm includes a utility that converts grey-scale into a monochrome color image. You specify the base color and it does the rest.

I just put in the extras in a folder called grand-canyon-mars,but the addon didn??t work.The jvv texture worked,but the appearance is strange,rather fuzzy:

And the grand canyon addon don??t work at all.
I??m using it in Celestia 1.3.1-1.The textures and normal maps are levels 0-4.

danielj,

What platform are you using? ie Linux,Windows?
All you have to do with the model files are downdload, extract, and copy to the extras folder. It works fine with version 1.3.2. That's the oldest version
I have. If you tell me what platform you are using I will try to build 1.3.1-1 and test to see if it works.

cartrite

Windows XP SP2.
Meanwhile,I will try in a later version...

Anyone,

I seem to remember that a model file used to require a texture name declared in the material section of the model itself. I found this to be unnessasary in versions > 1.3.2. This could be why it doesn't work with older versions.

EDIT:I tried version 1.2.4 and nothing worked? I noticed that most model files from that version were in 3ds format. Was cmod format supported in 1.2.4?

cartrite

I will download version 1.3.2 or later and try again.I don??t want to use it in Celesria 1.4.1 yet,because I need a test version.Anyway,I didn??t like the jvv Mars texture...

danielj,

From what I seen from your screenshots (fuzzy) you may like John van Vliet's Mars VT better if you edit *.ctx. MAKE A BACKUP FIRST. Then you can change the file size to 256 or 128. This should make the texture sharper. Something like this.

cartrite

danielj,

From what I found in some old docs, The cmod format was just getting started with version 1.3.1 and for a while only the ascii version was working.
My files are binary and I'm not sure when the binary version was supported.
It does work with version 1.3.2. If you really want it to work with version 1.3.1-1 then I would try converting it back to ascii with the cmodfix utility.

Do we still have to support version 1.3.1 specially for Daniel's pleasure?

Bye Fridger

Of course not.I tested in Celestia 1.3.2 and everything is fine now.Sorry!I didn??t remember that Celestia 1.3.2 was a great leap ahead the earlier versions.I will pay more attention next time...
