Old Pictures from Celestia (locked)

[John Van Vliet]

with and without the texture map that is ,only the normal map .

some might not agree but the gray images of the topo do look nice

Sorry but you guys need a separate thread for the moon data piccys... nice though.

@ JohnVV,

I actually agree. It looks pretty nice without the texture (not that I'd prefer it as such).
Pretty pics

John,

sorry if I am less enthusiastic about the appearance of your above normalmap display. I think the surface looks too uniform! Somehow like "sandblasted plastic" not like real rock that is characterized by many shades of gray. The evident excessive uniformity is clearly due to your applied technology.

But as you say, other people may have different views about it.

Could that really be helped? It is after all just a normal map. I wouldn't expect it to show a realistic texture, without a texture itself.

I agree that it looks too uniform to be realistic, but I think John was talking from the perspective of the detail we can see just from the normal map.

this is what i am talking about
Seeing as there are so few lola points . It looks to be about 90+% inferred as it is

as can be seen in the above "embossed-filtered" on mine and the 32k lola
the above is a 400% mag
the individual points CAN be seen on the right , along with the "inferred"( montycarlo - i guess) area inbetween

as time gos on THIS WILL improve .
But for right know there is a lot of "stripping

these are all the same area
one is mine the other is the "vanilla" lola.img



some like the "raw" image , i don't
there is always a "give and take" / "trade off" in something like this
but as time goes on it will improve ( unless the LRO lidar dies)
more and more points WILL get added

John,

all agreed, yet in my view a high amount of transparency of applied image manipulations in a scientific visualization context is important. I understand that you may be following a somewhat less strict aim in your add-ons.

Wow, nice model!

Anyways, While looking at Earth in Celestia, I found some intriguing artifacts in the 4k surface texture that you all probably already know about:



There are FACES appearing in the texture. I counted four faces and an individual eye.

Here's the highlighting of the faces and eye that I found.

Man, I'm not going to lie, that is stretching it quite a bit. Were you looking for faces?
Please tell me you aren't serious about this...

Lol. I wasn't looking for faces. At first.

I found the first one by accident, and was inspired afterwards to search for the other faces in the image.

I posted it simply because I thought it was funny.

Guess it wasn't funny after all. Sorry.

[Hungry4info]

Ah, sorry, it's my fault.

I should take a 10 minute break after reading new posts from the BAUT forum's ATM/CT section to clear my mind.

This is no photoshopped picture but an actual screenshot from Celestia. I've had great difficulty with the tree models because they have such a large polygon count. A small group of them makes the cmod 35MB!

[Fenerit]

Great! Which programs do you use in making trees?

[Reiko]

I no make the trees. They come with a models package I downloaded.

[John Van Vliet]

blender comes with a Python script to make trees ,though i have not tried it.

[Chuft-Captain]

Love the teleport model Cham, and the Earthquake zones Fenerit.
...As I live on the Ring of Fire, this last one is of particular interest... and I guess a teleportation device might come in useful in case of earthquake!

CC

ps. Are either of these going to be made available for download?

[fungun]

Fenerit, how do you guys do those cmods?
Is there some special program you put the data in and it draws the lines?
Thanks,
Tim

Chuft, the geologic Earth is now available for testing (add-ons releases).

For what concern myself, I do not know a specific program which build a wireframe CMOD. The CMOD's wiring procedure is called "linestrip" in CMOD language and can be achieved in several ways, either manually (text editing) or in automatic. I use a Perl script for this latter. You can find some informations around here:

http://forum.celestialmatters.org/viewforum.php?f=3&sid=d464d34dc8d8d621c4268e9f0daec795

but note that the scripting procedure is subject to be modified in accordance with the several cases your datasets have been built (e.g. whether the coordinates are xyz or yxz, whether you wish to wire amongst nodes (points' set) or not, etc. just to say). Anyway, is not so simple and can comport the use of more programs altogether, once be supposed your data comes from other formats (SHP, KML, etc.) instead of to be plain ASCII text (GMT, DAT, XYZ. TXT etc.). Basically, you can view a "linestrip" as merged points; in my case this latters are due to the cartesian coordinates converted in spherical (for the use around a sphere, otherwise simply you remain in 2D grid).

P.S.
In the link above, the script deal with points, for linestrip you must write into it "linestrip" where is "points".
