Photorealistic based scenery.

Postby f-ojac » Thu Apr 24, 2008 1:25 pm

Hello,

Here in Brittany we have the luck to have the possibility to use pictures taken from an aircraft :

http://www.brest-metropole-oceane.fr/vueduciel/

and to use them under a Creative Common licence.

I would like to try to implement those pictures into FlightGear to see what it gives seen from the air.

I have quite a good experience now with terragear, taxidraw and the like for scenery building. Could anyone give me some hints on how to implement those pictures into the tile building process for FlightGear ?

Thanks in advance,

Oliver

good to know someone's working on this ;) I think it has got something to do with SGI files and gimp... I know someone did a similar thing with Paris (but only Paris, would be cool for other hotspots like the the california area)

Hi Oliver,

I like your idea and hope you'll be successful!

If I were you then I would ask for some help on the FRENCH FlightGear forum

http://fr.flightgear.tuxfamily.org/forum/

- especially address "helijah" (Emmanuel Baranger) and "Nels" (Benoît LANIEL), the two authors of the PARIS *GROUND TEXTURE* scenery.

Might be you could be surprised :roll:

Thanks everyone for your informations.

I am now working with the French team to get it set up. We are close to a solution, I will let you know the result and hopefully post some pics soon.

The work is somehow a bit different from the Paris scenery, as it is not a simple XPlane conversion, but a full creation. With a 20cm resolution, I hope it will be a great step forward.

Yes, you are right, 1 pixel has a 20x20cm resolution.

See http://www.brest-metropole-oceane.fr/vu ... photo.html for the technical details.

See here to have an example of what it gives on the airport of Brest :

http://www.brest-metropole-oceane.fr/vu ... 01_106.jpg

Sure there might be a problem on the delay to display those textures, but we're going to try, it's a nice challenge !

The first results can be seen here :

and here :

http://helijah.free.fr/LFRB/fgfs-screen-002.jpg
http://helijah.free.fr/LFRB/fgfs-screen-003.jpg

The resolution has been however lowered from 20 cm to 1 meter in order to avoid a too strong performance loss. There is still a lot of work to be done but well, this shows it is possible !! There is in the pictures above no performance loss !

Best regards and thanks to anyone who has been working on this test (Helijah & Nels).

Oliver,

this is visually stunning. What to say more? New dimensions for the FlightGear world.

So I'll keep on flying Paris until your scenery gets availabe.

Keep on your wonderful work!

i think users would appreciate it if we go onto the next hotspot, San Fransisco :D I can't speak french ( :( ) but I would like it if I could do this kind of thing myself, or know how to

The hardest is to find pictures that are free of use ! In our case we have the opportunity because they have quite a flexible licence. If you have such pictures for San Francisco, then it's easy. We'll definitely write a howto on how to do this. But I do insist on the fact that it is more a licensing problem than a technical one. Some cities around the world (and Brest is not the only one) made this kind of pictures for their own purposes. So just try to find them and have a good licence agreement !!

Ok, thanks ^_^ I know the UK has a state-owned surveying company which publishes their maps, not sure about the licence. I'll have a look, thanks :D

Hi Olivier,

there is one very important question left for me and I hope you are able to answer

Here in Brittany we have the luck to have the possibility to use pictures taken from an aircraft :
http://www.brest-metropole-oceane.fr/vueduciel/
and to use them under a Creative Common licence.


I copied a little piece of one of these aeriel-pictures, modified it a little with GIMP and made the texture for a parking-area for EDDV with it:
Image

Do you think the Creative Common licence allows me to share this texture with a model under the GPL (EDDV airport models)?

Thank you very much in advance for answering.

Regards
Georg
