[Flightgear-devel] scenery appearance depends on camera tilt angle
What steps will reproduce the problem? --lat=37.637855 --lon=-122.414915 --altitude=656 --heading=113 --fdm=ufo aircraft is stopped. zero airspeed, zero rate of turn, etc. The choice of aircraft doesn't seem to matter; this is 100% reproducible chez moi using the default c172p, the pa24-250, et cetera. Zoom in the view; FoV 15.5 will do; 12.5 is better; 7.7 is even better, if you have good control of the pitch/tilt and view angle. Change the view angle, either by pitching the entire aircraft or by simply tilting the pilot's view angle relative to the aircraft. What is the expected output? Scenery should not change. The ray from each object to the camera image plane should stay the same, except to move to a different point in the image plane, when the camera is tilted. What do you see instead? For some tilt angles, the taxiway signs alongside taxiway charlie are dark, while at other title angles they are lit. http://www.av8n.com/fly/fgfs/img48/taxi-signs-off.png http://www.av8n.com/fly/fgfs/img48/taxi-signs-on.png I cannot imagine what could be causing this. == The same phenomenon is seen during normal flight, but is harder to reproduce and document. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Hi, FWIW, when I'm flying, I see the shading on the scenery change drastically during the flight as the plane turns and pitches. I think what's happened is instead of just changing the shading on the panel, we're changing the shading on the scenery too. FGFS didn't used to do that, so it's a relatively recent introduction. All the best, David Now I understand- the whole scenery! (But THIS John never mentioned) And he had should wrote, that shaders are disabled. That's the cause of the bug I guess- when shaders disabled the shading is changed. That's something really noticeable above the sea or a lake. And yes, as we offer FGFS for using without shaders as well, it is a bug. Heiko __ Do You Yahoo!? Sie sind Spam leid? Yahoo!

The mesh representing the back of a sign is not complete; graphics state from other parts of the scenery are leaking into it. The particular effect depends on the global draw order, which does change as your viewing angle changes. I don't know why this ever worked. What color are the sign backs supposed to be?

[Flightgear-devel] To Pause FlightGear Instance using sockets
Hello All, I am a FlightGear user and I have written a program that communicates with the FlightGear using UDP sockets. Now, I was wondering if one can pause the FlightGear instance without using the pause button 'P' via sockets while communicating with the FlightGear instance.

Re: [Flightgear-devel] instrument patches
Hello James , I just updated your commits and tested , thanks. But I see another issue that bothers me ... originally I didnt initialize the parameters UNLESS the airspeed indicator had an overspeed needle ... but now even without , the alt-threshold , ias-limit ,and mach-limit are visible . That seems unneccesary , and confusing , and the reason I did it the way I did. I'd prefer them to not be there unless needed , unless someone can see a reason they should, that Ive overlooked .
