Dear Olivier,

this is really a nice job!...flying over Brest was wonderful. And just because I do presume that the experience would be exciting for other FG pilots too, here's some shots:

Even if there are some limitations (for better look, you have to fly at a proper altitude), the overall result is awesome...
Could you give us a workflow in order to achieve these results?

Thank you again, trés beau! :D

PS:...flying at dusk/night, there are no lights on Terrain. My problem, or something missing?

I'm wonder why this patch still not in git.
Its awesome feature - so easy made phototerrain, wihout xml, just add-delete files!

For US there is some free aerial photo sources, and it very easy to make things like this.

Also its very easy to place landmarks in correct places: just export image from OSM, copy it to certain folder and voila! Place object, then delete image.

Can't believe that there is cons to modify present shaders.

Technically, yeah you're right, it's easy to do -so easy, even I might be able to do it, if I give it a try!

However, this is the real world, so there's that big wall of a problem called "licensing issues".

Because FlightGear is released under the GNU GPL license, which only allows work released under the same license to be used, we can't use most of those images.
The images are usually either proprietary, copyrighted, or Creative Commons if you're lucky.

So there's a legal barrier that keeps us from putting the photorealistic scenery into the official database; it can only be released as a third-party addon, at most, sadly...

-If I made a mistake in my explanation, please feel free to correct me, thanks.
Look for "B-BIRD" "N127KY" or "AVA0004" -that's me.

Despite having over 1700 posts here, I am not even close to being the most skilled guy here... I'm just words and bad drawing, not experience. :P

It's right, but could be possible to write easy tutorials for individuals who want to make it for themselves. :wink: Isn't?

What problem with third-party?
A lot of scenery, textures and models are released not GPL. With only GPL products FG cannot use all potential. Just look at CORINE scenery, scenery addons with OSM, Tu-154B, E-JET170 etc. Noone who use it say no word against it that it's not GPL.
I can upload files for KSFO area (also I hear that Gijs make photo GrandCanyon), but even git users cannot use it as patch become working not well (

And we can use not only actual non-GPL photos - textures may made in Terragen, in Gimp from vmap_0 screenshots as base, etc.

Thanks for your feedback + nice pictures. As mentionned earlier in this post even if I was at the source of the idea and if I asked the authors of the pictures for their permission, I did not myself made the transformations for the pictures. And the guy who did never had the time to write a proper howto, maybe one day.
I know he has tried to make it simple and published a patch, but without success AFAIK.

That might be because the pictures are slightly "flying over" the terrain, and therefore the lights may be under.

@I-NEMO

1) apply patch to SimGear and shaders
2) download geotiffs with desired area (I took from here)
3) in Qgis crop them by tiles size (depending of lat/lon) and stretch it to ^2 size in Gimp
4) convert it to dds (like 942058.dds) and place it next with your tile .btg

Dear all,

the pictures of the Brest scenery look fantastic. Unfortunately I can not get that scenery to work.

After compiling the git current version (FG2.5) on ubuntu (11.10) using makefg-1.3.6, I applied the patches from
    blaniel.free.fr/pub/flightgear/brest
as had been suggested in this thread and downloaded and unpacked the brest_photo.7z. The .dds files are now placed just next to the corresponding .btg.gz files. (Changing materials.xml apparently is not necessary any more with the new patch).

The patches went through well except for the terrain-default.eff. It seemed however easy to add the lines by hand at the right place (hopefully).

The compilation crashed at obj.cxx with
    simgear/simgear/scene/tgdb/obj.cxx:605:19: error: variable ‘SGBucket b’ has initializer but incomplete type
This could be circumvented by adding
    #include "newbucket.hxx"
to the header of obj.cxx and copying the file into the same directory. (There are surely more elegant ways of doing this).

Then the code compiled well and it looks like the .dds files get loaded: when increasing the log-level to 'info', the log says
    Adding overlay image 2876050.dds
    Adding overlay image 2876049.dds
    Adding overlay image 2876058.dds
    Adding overlay image 2876057.dds
Still, the textures are not displayed when being around LFRB. (Also, the panel of the C172p is missing a number of elements like the instruments or the NAV/COM).

However, when looking closely around LFRB, it looks as if there *was* the good texture in a small strip just around the runways. The display is clearly different than When removing the dds files from the scenery directory. Is it possible that the Brest textures are hidden below the standard ones? If so, how could that be changed?

Any help would be highly appreciated.

With all the very best wishes,

Peter

so I downloaded the brest package copyied the readme xml file to the materials.xml file in fg data folder. making sure I only copied the right part of that file, into just before the property list

I 'cp' the terrian data to my fg scenery terrain folder once with the w010n40 as its own folder in fg/data/scenery/terrain main folder

once to the fg/data/scenery/terrain/w130n30 sub folder

and I created the folder Brest under fg textures and cp the contents of the downlaoded Textuers to that folder

but when I pull up the airports list and click Brest I get's nothing. Am I missing somthing? my only other thought is maybe I have to download some patch I saw on the wiki but I thought that just ment if you wanted to create your own P.R scenery. Maybe you have to have the git version as well.

any help would be much apreciated thanks and this looks amazing

Does this work fine with Flightgear 3.0?
Thanks.

Quite an old experiment now, seems the latest tests weren't successfull. OSGEarth might be a better solution for the future, even if there still are a lot of things to improve to achieve a good result (in this experiment, we were missing the trees and water reflection, for instance).
