Use flight gear as out world scene generator?

Postby Droogie » Mon Apr 09, 2018 3:03 pm

I would like to send airplane state, position, heading, roll, pitch... and see the appropriate view for the current state, couldn't find examples for that.
I'm New to flightgear.
Can someone refer to an example ?
Thanks

There have been a few people doing this. I know one of them is Elias Tarasov, who used FlightGear as a visualizer: https://m.imgur.com/qvoTNMR

I don't have any specifics on doing this, but if you search the mailing list archives I think you'll find the relevant threads.

there's also several topics here in these forums about it... i think a lot of them are using mathcad??

Yes, I'm talking about an external application that will do the state calculations, and I would like to send these outputs every XX ms to FlightGear application so it's state will behave accordingly.

Usually people seem to hook it up to matlab, so if you run a search for that over the forum/wiki, you might find something useful.

It seems to be a fairly frequent application.

im not using Matlab (not familiar), just trying to send simple data over socket from python script:
Code: Select all
UDP_IP = "127.0.0.1"
UDP_PORT = 5500
packed_int = struct.pack("f",33.33)
packed_int += struct.pack("f",33.33)

MESSAGE = packed_int

print ("UDP target IP:", UDP_IP)
print ("UDP target port:", UDP_PORT)
print ("message:", MESSAGE)

sock = socket.socket(socket.AF_INET, # Internet
                     socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))   


i have tried it with or without protocol.xml (does this necessary?), nothing seems to had an impact.
does this the right forum for these issue ?
thanks

What kind of documentation did you use for your tests so far?

Combination of Readme.io, Flightgear wiki and random pieces of information on the net.
