Photoscenery generator for Julia compiler

[abassign]

I've got julia version issues again... I've got 1.5.3 but it says, it wants me to install 1.5.0 which is a lower version.

This is a typical case of installing from some Linux distribution. As I wrote in the manual it is likely that you need to have at least version 1.5.4. However, it is always advisable to try first, if the problem does not start is of version, in this case follow the instructions that are found here: https://medium.com/coffee-in-a-klein-bottle/install-julia-1-5-on-ubuntu-bb8be4b2571d
However if you have any difficulties write me and tell me the OS and version you are using.

I just updated the repository with version 0.3.10 of the program, the update brings some improvements that I list below:

Autimatic rebuild of the airports.jdb file
Upon a user recommendation, I have inserted the automatic rebuild of the airports.jdb database file if found corrupt. The database file takes the data from the airports.csv file always present in the directory that contains the photoscenary.ij program.

Pkg.build("CodecZlib")
The CodecZlib module is sometimes problematic in version management if highly complex packages are installed. The only practical solution is to require the module to be recompiled with the Pkg.build function. Not being able to know the actual installation status of the files, I found it much more convenient to run this command anyway even if the CodecZlib module was well installed.

Here is the manual that explains the --route parameter:

Here is version 0.3.10 of the GIT program
https://github.com/abassign/Photoscenary

My route file is named KJAX_KMIA.xml
on command: julia photoscenary.jl --route KJAX_KMIA.xml -s 0
the program will process, but
on command: julia photoscenary.jl --route kjax_kmia.xml -s 0
I get two errors:

Error: loadRoute in the route file: kjax_kmia.xml
Error: processing will stop! The LAT or LON is invalid (Exit code 405)

It seems that the file names are case sensitive, but the error codes don't mention that.
If I'm correct, a better error message would be "Error: file not found; file names are case sensitive."

[merspieler]

Well... it is common (except for windows) that file names are case sensetive and hence shouldn't need mentioning.
Also imo the error is clear enough, that the file "kjax_kmia.xml" isn't found, if the file is named "KJAX_KMIA.xml"

Hi merspieler, thank you for the reply. I think sometimes it is not so intuitive, especially for those of us not used to working in a terminal with a command line environment. I just learned that while the file names are case sensitive, the image directory path is not; for that path, "D:\Photoscenery" works as well as "d:\photoscenery".

When I read the error messages about the file not loading and that there were LON and LAT errors, I started thinking (and checking) whether the flight plans were correct, whether there was a problem with .gpx vs .xml, etc. In fact, the problem was much simpler as we now know. IMO the more explicit the error message, the less time wasted trying to determine the root cause, and less need to post in the forum or contact the program author for clarification.

This program is so very impressive, I will try to post an image here, -s 2 at 10000 feet MSL heading east over Long Island, New York from KJFK to KACK.

Just a quick question, can you use photoscenery on 2020.3.11 or do you need the latest nightly?

Thanks,
Delta

Some post were moved here from New Aircraft - Promecc_Freccia. One additional quote added for context.

Orthophotos can make a considerable improvement to your scenery. Check it out: https://wiki.flightgear.org/Julia_photo ... _generator

Yes, get ortho scenery, with your GPU, and rather low altitude, I'd recommend using 16k resolution. If you need help with it, feel free to drop me a pm.

As for recording, use obs and for publishing I'd propose using peertube as it's an open source platform and supports federation.

I did the integration of the orthophoto... here the result:






I'm not 100% happy! Coastline is poor... let's say a bit ugly! looking for landmarks is not easy as well. I could not find local airfiled "Fondone" https://goo.gl/maps/LtQ97VZCHpetLkK19

The DTED is also poor... can the fidelty of the terrain elevation be improoved?

I can live with this anyway! My goal at moment is to focus on the development of the aircraft!

[merspieler]

Setting the water effects to the lowest settings doesn extend the texture over the water (at least on next branch) which makes bad coastlines way less noticable.

As far as I can see, the Fondone Airfiled (ICAO: LINK) isn't in flightgear.

For increasing the fidelity of the terrain there are two issues: a) finding a better data source (especially, if you want to publish it as you are then limited to some copy left licenses) and b) can be quite an effort to rebuild the scenery using that data... depending on how big the area is. (also border of the new and old scenery has some issues)

EDIT: Your pictures don't even show the ortho scenery, is that intended?

[Delta5142]

Yeah, that’s not photoscenery in your screenshots. It looks like the traditional WS.2.0 scenery.

Ok...then I'm doing something wrong! I generated the DDS files with the julia stuff in 16k... but FGFS is not pointing there... what shall I do to use the orthophotos?

[merspieler]

In the launcher, under Add-ons, add another entry under "Additional scenery folders".
You've got to point it to the directory that contains Orthophotos directory.

[V12]

I tested 16k photoscenery on the customer's machine i9-10900 with 24GB RTX Titan and observed big lags while FG loaded that images from .M2 SATA drive. How user can avoid this lag ? It is hardly usable

[merspieler]

You can by improving to code to load the images in the background...
... or maybe by implementing a LOD for orthoscenery... dds can have prerendered mipmaps

[SDeAstis]

Hi,
I did that, but is not using the DDS files at 16k from my Orthophoto directory.

[merspieler]

Is your GPU able to handle 16k textures?

In the sim go in the Menu to Help -> About there you can see the Max Texture Size, if it's 16384 or higher, that isn't the problem... if it's lower, you need to use a lower resolution.
