I'm not Chris (you know him as a Borg), I'm Brian .
Can you make a 16k texture of the Earth?
Also, why I haven't seen here a maybe 10k texture? Does the texture must be in powers of 2?
Some Rookie Questions here ...

What am I doing? Ah, nothing much. Just laying on my bed, watching the stars, and sky, and keep asking myself: 'Where the Hell is my Roof?'.

First you really should make your own account so we can keep you guys straight!
Secondly you can't use a 10k texture. All textures must be power of 2 shuch as 512, 1024, 2048, 4096, 8192, 16384, and if posible 32768. I don't know if Chris, Celestia's author could build in the ability to use off size textures. I think it has to do with how the drivers and video cards work that lock us into these sizes. It would be nice to be able to use what I would call on the fly textures. Say a texture that is 10000x5000 or 21000x10500. But at this point I don't think its posible.
Hope that answers your questions.

Ah, never say never!!
Past texture releases, Hmm let me think about it
Thanks for your understanding.

I am with you now... Chris is in Hospital...
You know that he is the Borg guy, "WE" stuff, "Subroutines", "unimatrixes" and Gene Roddenberry knows what else...

LOL I know some Sci-fi buffs just like you
Hey Brian you really should make your very own forum account.
we know you as an individual now, make it official.
Also how is Chris, hope he is well ?
Tell him i said hello.

To Guest,
There are 2 tiffs that are 21600x21600 in size. They have to be resized to 16384x16384 and they must be put togather to form a single texture of 32768x16384. Not any easy task if you don't half the right tools and or a great deal of RAM. Like at least over 2Gigs of RAM from what I am seeing. Maybe 3Gigs would be better. I gues I will have to save up some more money.

I almost forgot to mention, I visited Chris... he is feeling better . I told him about your "Hello" Darkmiss, he was glad He told me to send this message (I had to write it down ):
"The Collective appritiates your concern. We had suffered large quantities of Internal damage to our Sensor arrays and Secondary Function Subroutines. All Recovery and Repairment Drones are repairing, replacing the damaged Parts adn recovering the Data from the damaged Data Nodes. The rest of Collective's drones are Regenerating and adapting to current situation to counteract it. We shall be fully functional in 5 days, 8 hours.

billybob884,
Be forewarned that they are huge. The west tiff is 240mb and the east tiff is 400mb. So if you don't have a fast connection it can and will take a while to download. Here are the links
ftp://visibleearth.nasa.gov/pub/EARTHVI ... o_west.tif
ftp://visibleearth.nasa.gov/pub/EARTHVI ... o_east.tif
I would recommend using a download manager to aid in the download.

Well it turns out the black bands near the horizon were my fault. In my haste to view the 32k texture for the first time i just stitched it together with a 16k texture with full mipsmaps created with my 'devil' tool.
This seems to leed to none of the mipmaps been visible and hence the dark patches.
Since making all the mipmaps individually and stitching them together the texture is now visible all the way to the horizon which makes for even more spectacular views!
Don,
As for stitching your two bits together. At first i made a program with devil to do it but it failed too. The only thing that could manage it was 'netpbm'.
This is a command line tool though so may take you a while to figure out.
It you want my devil tool which has alot less option then nvdxt but is a lot easier to use then pm with your email or ask jim to put it up for download.
if nobody else makes the texture fairly soon i'll try and put all the required tools, dll's and .bat files in a zip file so making the texture will be trivial once you have the tiff's converted to jpegs. making it from the tiff's causes the colours to come out arseways and i havent been able to fix this yet.

Applause to you!!
It took me very long to download the 16k Texture package, so I guess, I never will be able to see your 32k textures in reatime, cuase here in Luxemburg we are also tuck in the middle adge of Internet devlopping
(my english isnt the best, hope you understood what i meent)
how big do you think must i scale my virtual memory, to see again the 16k texture + 8k bumbmapped earth. since I reinstalled windows, i wasn?t able to seen them any more .

Did you meen these raw files, or a ready made 16k earth file for Celestia ?

I think this 32k Earth will elude us all!!
Thank you guest for considering my shallow water in the mix, but I think it just won't happen.
I will have to buy a dedicated machine just to put together this 'monster'. I just can't afford it right now. It's really great though to see what is possible and is a inspiration to keep going!
Maybe Don could brief us on the ideal spec to put this one together? Money no object...of course!
Regards...bh.

Star Lion,
Its not a .bmp file it is a .dds file made from a .bmp. Most .dds files are made from .tga witch are just as big or bigger than .bmp files. Pixel's converter simply uses .bmp files instead. Converting any high res texture to .jpg should only be considered as a last resort as far as I am concerned even at .jpg's highest quality setting. Just my opinion.
