Use Celestia and textures on TV or things like this

Slalomsk8er · Post #1by **Slalomsk8er** » 26.07.2004, 19:29

Maybe i soon work for a regional TV-Station (Basel/Swiss) and my project for to get in would use Celestia and some community textures/addons.

So my question is: "which highres/VT textures and addons can I use for free(credits) and for which i have to pay?"

By the way I am planing on some free Python scripts to make the creation of VT's easy. Doing now a Imagegrabber for 1000+ orthophotos like this
http://maps.geo-bs.ch/regio_ortho_750/608750_277250.jpg
configurationfile based (URL / savepath/ savename), the script can be called with one Image for DL as arguments or controlled interactivly (one Image).

I will post the confgenerator and the grabber scripts in this forum wenn finished.

Hi and welcome Slalomsk8er,

All the files at http://celestiamotherlode.net are available free of charge.

I am looking forward to your scripts. They shoudl make it much easier for people to create the VT close-ups of hometowns big buildings, etc.

Cheers,
Joe

Is this still true for publishing(TV)?

I am looking forward to your scripts. They shoudl make it much easier for people to create the VT close-ups of hometowns big buildings, etc.

I hope so, plus Python is easy too install and will work for all (mac, linux and wintendo).

I started with a orthograbber but what else is needed in the Python texture tool box?

join/cut
rename to VT name format (for rectangels with known corner coordinates)
...

I have no problem with anything of mine as long as credits are given...

VT textures might be an overkill for standard television unless you plan on some close shots of any planets...imho

What exactly are you needing and then we could direct your efforts more efficiantly...

I plan to do some thing like spacenight. The original from german tv had cool sound, sateliteimages, hubblepics and stuff like this.
At 2 in the morning with all this call my baby shit it was a realy relaxing thing (the best for tv-sleeping ;-)

).

The other I am planing is for sports to zoom at the beginnig of the match from space to the stadion but this is out of my range at the moment (CHF. 200'000.- Swiss (50cm/pixel) and Basel (12.5cm/pixel) ortho photos ) plus the need for a 3D model of the stadion.

this board auto log out seem to be a bit too fast cus I was logged in!!!

edit: it is not the time my last post took me a while to figure out ;-)

Is this right:

VirtualTexture
{
ImageDirectory "earth-unshaded-hs-32k"
BaseSplit 0
TileSize 256 # real 512^2
TileType "dds"
}

at level 10

the resolution would be:
40'076.592km * 20'004.5765km (Earth U-equator * 1/2U-poles)
= 801'715'250.523288km^2
1'048'576pixel * 524'288pixel
= 549755813888pixel^2

km^2/pixel^2
= 0.001458km^2 per pixel^2 (pixel^2 is a joke it is pixel ;-)

)
= 1458.3115089m^2 per pixel

= 38.220 m per pixel horizontal
= 38.156 m per pixel vertical

:roll:

the free ortho from Basel is 10m per pixel

You can always make the tile size bigger at the lower levels,Celestia still works so long as your graphics card can handle the bigger textures,Jestr

At lower levels it is ok but i like too zoom to my house, so i need a bigger tile size at level 10 i think.

Can I start with 512*512, switch to 1024*1024 at level 5 and switch to 2048*2048 for levels 8,9and10 (GeForceFX 5600 256MB)???

512MB of RAM is nothing I see 3GB is what I need for celestia and a RAID and the newest GeForce ;-)

By the way has enyone a Image from Earth 1024Kpix to 512Kpix ?

yes it should work with different size tiles no problem so long as they are powers of 2 (512,1024,2048,4096 etc),the limiting factor normally is how big textures your graphics card can handle,Jestr

The first Tool is usabel. It is the GetPicFromUrl_1.0.py

Download it now
use right click -> save link to disk

next will be a script that produces configfiles for this script (bulk downloads), this makes it cool for to download orthophotos and any other tiled Images easy!

PS: PM my the bugs you find. You will have to install Python first and till now the code is just tested on wintendo ;-)

Hi Slalomsk8er,
You might want to post at least some documentation for this script, if you want it to be useful to others.

Cheers,
Joe

run it and you will see(it is comunicative) or look in to the source python is realy easy
