Citation-X route/fix display fail solved

[SurferTim]

I fly a version of the Citation-X from the download page. The last time it worked was with FG2019.2.0. Even the OSG text fix did not fix this display.
http://mirrors.ibiblio.org/flightgear/f ... ationX.zip
My version is here. I had it private until now, but I would like to get it working again.
https://github.com/SurferTim/CitationX
It had a great route/fix display and TCAS, but it has failed. The display remains blank (black) even after loading a route.
I know the function is still there because I can "poke the bear" by messing with the radar.png image.
If I remove it, the display fails with a white rectangle.
If I put text on it, it gets erased after loading and displays all black..
I believe it may be putting text and symbols on radar.png, but they may be like the Garmin GPS, the same color as the background (black).
If this had been deprecated, what replaces it? I saw the Patten Hangar Citation-X has a working display, but that aircraft has problems that I wish not to inherit.

This is from /Models/Instruments/MFD/nd.xml

Hi SurferTim,

Have you tried this one ? http://pattenflightgear.wifeo.com/cessna-citationx.php

[SurferTim]

Yes, I have tried the Patten hangar Citation, and it has yet to complete a flight without crashing FG back to the Ubuntu desktop.
The last attempt started out with the instrument panel looking like a bad acid trip.

It does have a working route/fix display, but I have yet to figure out how to implement it in my version. Like I said above, I don't want to inherit the problems with that version.

i've flown this CitationX and have never seen this display issue. my graphics card is an old Nvidia GTX750Ti on a single-screen setup.
i've also not seen FG crashes that could be attributed to the aircraft model. i had FG crash but for other reasons like libcurl or the particle system.

[SurferTim]

Thanks for your input. Maybe it is because I fly with three displays with a GTX1050?
If it means giving up the 3 displays or using another aircraft, I choose the other aircraft. I really like the displays.

Edit: What I was really hoping for was to get the route/fix display fixed in the aircraft I use now. Or find a suitable replacement for the MFD.

[SurferTim]

I found a page on the canvas ND frmework. It refers me to clm76.
https://wiki.flightgear.org/Canvas_ND_framework
@clm76: I'm supposed to ask you about mods to the ND function. Well...?

Edit: I tried the Patten hangar version again. I think it has to do with the 3 displays. It shows about half the frame rate as my version. I show 58-60, that shows 28-30 with FG2020.3.3.
I tried the Patten version with FG2020.4.0, and the frame rate on one screen is around 30fps, and with the 3 displays, about 15fps with bad display flickering.
My version falls to 30fps with FG2020.4.0 on both the Twin Otter and the Citation. Previous FG versions 60fps.

Hi SurferTim,

Here is a test :

2 versions of FG : 2020.2.1 and 2020.4.0
2 versions of the Citation : X (PFD, MFD, CDU coupled) and X+ (PFD, MFD and CDU independent)

Difference in fps in the same conditions (on the ground, flightplan and fms activated) with 3 airports :
LFOH (medium size airport, scene well implemented)
LFRK (medium size airport, poor scene)
LFPG (large airport, very well implemented)

2020.2.1 : LFOH : X = 52 - X+ = 41
2020.2.1 : LFRK : X = 55 - X+ = 45
2020.2.1 : LFPG : X = 36 - X+ = 32


2020.4.0 : LFOH : X = 42 - X+ = 35
2020.4.0 : LFRK : X = 49 - X+ = 40
2020.4.0 : LFPG : X = 31 - X+ = 25

As you can see, the scene around the plane strongly impacts the fps as well as the Fg version.

[SurferTim]

So you are offering no fix for me?

[clm76]

My version is here. I had it private until now, but I would like to get it working again.
https://github.com/SurferTim/CitationX

Sorry, but your url is not working (error 404) and, yes, I can look at the problem if I have the right plane

[SurferTim]

My bad. I made the Github version private again because I didn't want anybody downloading it, then complain that the display isn't working.
It is public again. Let me know when you have it and I'll make it private until fixed.
Thanks!

Edit: That Citation in my Github directory has been private for the last year because of the route/fix display. I was hoping that when the OSG text problem was solved, this would be also. No luck.
I will guess the Citation in the download hangar has the same problem. I don't know who maintains it. The only credit on it is Syd Adams.
The MFD should be the same in my version and the download page version. The PFD in my version is different. Honeywell gave me a PirateAir PFD.

Downloaded !

[SurferTim]

It's private again. I really appreciate the time and effort you are donating to this.
Thanks in advance.

My old versions of the MFD (like yours) didn't work anymore.
I think the best thing would be to switch your MFD to canvas. You would thus find colored texts.
Unless someone has another idea

[wkitty42]

if i'm not mistaken, the colored text problem has been fixed a few weeks ago... OSG 3.6 can now be used if you are building your own FG installation... it should also be being used in the new builds of 2020.3 but i'm not totally positive about that... i know it was posted on the dev mailing list and i saw the commit(s) for it in the commits mailing list...

[SurferTim]

@wkitty42: That is correct. As of FG2020.4.0, I no longer have to use an old OSG to compile.
I have posted that in this thread
