Didn't find this topic discussed using the search function so I thought I just bring it up. :)

I've been flying skirmish quick missions over Lille recently and was impressed by the detail of the city buildings. Flying over the "island" shown on the attached screenshot I wondered however what it may represent given its rather symmetrical shape.

Googlemaps gives us the following: Citadel at Lille
It was built some time in the 17th century and using the satellite view function in the link one can easily see how impressive it must have been and probably still is.

I can well remember my first PC flying days as a kid in Dynamix' Red Baron and how great it was that even in 1990 we had landmarks such as the Eiffel Tower and Big Ben included in a flight sim.

So I was wondering did any of you guys who have a great understanding of the aspects of ingame modeling ever consider building the Citadel at Lille?

Any feedback welcome :S!:

+1, hopefully someone can assemble the stronghold. :)

Edit: challenge accepted! :S!:

Even just the walls would be good in my opinion, we'd also need a few in Verdun and the like.

Ok, I got to admit I have started doing a little bit of mapping, but no promises. ;)

This would be a great project, but it seems daunting. I would love to see it added to the game.

Geography starting to come along, though having some problems getting a hang on the height differences. If anyone got any more (detailed) material it would be great! :) Especially needed for the layout of the buildings.
I know now there is a museum at the citadel, anyone in the community living in Lille and are able to go there take some photographs? :lol:

For the buildings layout, here a screenshot with the building footprints overlayed (in transparent pink) on an aerial photograph. Only the buildings (not the fortress walls) are displayed, and I think the dark pink building wasn't there in 1900.

For the height differences, I can't help much now (I'll check next week if I can get a DSM on this fortress… maybe I can have something). In waiting, you will have to guess.

The following video maybe an help to guess (when comparing to the mans, the inner building height seems to be from 12m to 15m to the rooftop, and the fortress inner walls are as heigh as the highest building rooftops).
You can also see many building details on the video:
INA video (1972)

Following some lesser images and links that can be also (maybe)useful:

Wow, that looks really fantastic! :S!:

Once you have finished it, what would be the next steps before it becomes part of the sim?
Is there an ongoing project for modelers to provide their work to 777 so the developers can implement the models in an upcoming patch?

Rama: Not sure how accurate the structural mass of today is versus 1910, I'm basing the layout partially on the photo of today and this: http://img819.images...elwwwarchit.jpg" onclick="window.open(this.href);return false;">http://img819.images....us/img819/673/ … archit.jpg
Would love to see that last plan in hi-res, hard to measure the height, but gives a good idea of the profile of the defences.
And the dark pink building I believe is the chapel, it shows up on even the earliest drawings of the bastion dating back to the Renaissance. Maybe it is marked in dark because it is the only original structure left?
I looked up the links, It'll be of great help when modulating courtyard(?) /inside of the walls, thanks a lot! I don't possess the language skills to go look up French sources. :)

Olli14: Jason posted here earlier that We make no promises that we will accept new scenery objects as official.

So the chance for anything of getting a finished 3Dmodel in to the game is never given. Beside that, I just realized this is a damn huge project that will not be any time soon at acceptable quality. The piece of land in this project is 250,000 square meters, give or take. :lol:

Also, my 3D modelling skills grow proportionately with the progress of the project, 3D in AutoCAD is not like ArchiCAD, and then comes 3Dmax. >.<

Hello everyone,
have you tried RealityCapture? https://www.capturingreality.com/Home
 
RealityCapture is a state-of-the-art photogrammetry software which automatically extracts beautiful and accurate 3D models from images, laser-scans and other inputs.
It is able to process laser-scans and scales linearly, which especially makes it unique to anything else. This software is the only one to mix laser-scans and photographs easily without seams at astounding speed. The algorithms are out-of-core so you can reconstruct unlimited size models on limited hardware (a PC with just 8GB RAM). The models are complete and without seams. Of course, geo-referencing using ground control points, flight logs, gps in exif go without saying. There are also more advantages like camera-rigs support, arbitrary ortho-projections, nice and intuitive UI etc.
 
Have a closer look at what RealityCapture is capable of: Reconstruction of a castle - interior, exterior, all in one model. 28 975 images of 36 or 80 Mpx resolution. 118 terrestrial laser-scans (Leica). It all has been processed on a single PC. The model consists of 1 500 000 000 (1.5B) triangles: https://youtu.be/E7LLELllus4.
Few others:


Here you can see the advantages of automatic mixing images and laser-scans: https://youtu.be/1-4RsCIuKCw.
 
You can download a test dataset here: ttp://rcdata.capturingreality.com/testset1.zip.
 
The software also allows you to filter, simplify, texture, export model. You can also export -> post-process (retopologize, clean) -> import -> texture your models...
