Re: [Flightgear-devel] Tower view configuration
From: Drew [EMAIL PROTECTED] Thanks, I'll try that, but I don't understand your description. The view origin is fixed in space as it is. Since the field of view is only 8 degrees horizontally, I figured the .9 degrees would shift the target upwards by about 1/6 the height of the image. That's what I'm trying to do, anyway. In any case, I'll try what you suggested tomorrow when I'm at my computer, and see for myself what it does. Hmmm...ok I did not see that. Now I've got a better idea of what you are looking for. Also I need to retract what I said about the camera angle. That's a function of manipulating the origin. The pitch-offset-deg value will have no effect in lookat mode. Currently the only thing you can do to move the aircraft up higher in the tower view is to specify a target-y-offset-m. This moves the target location. What it won't do is maintain the same angle as the distance to the aircraft changes. Doing that would require a code change that uses new parameters like target-pitch-offset-deg and calculates an xyz value dynamically.

Re: [Flightgear-devel] Tower view configuration
You could write a nasal script that updates target-y-offset-m based on the aircraft's distance from the tower. You can get the tower and ac position from the property tree, nasal does trig, and that's all you need. Josh I'll look into that.

Re: [Flightgear-devel] Tower view configuration
From: Drew [EMAIL PROTECTED] Hey All, I'm trying to configure a tower view in FlightGear that is offset in pitch such that the airplane appears above the center of the screen, but still tracks the position of the aircraft. I can't figure out how this is done, as the 'offset-pitch-deg' property seems to have no effect. Here is what I have in preferences.xml. If anyone knows what I'm doing wrong, please let me know. That negative 9 tenths of a degree offset-pitch-deg value is going to be hardly noticable. If I recall correctly, the offsets in lookat mode still manipulate the angle of the camera, but the target is always constant. Thus it gives you the impression that the camera is teathered to the target, and rotates around as if on the inside of a sphere where the target is the center of the sphere. Try some larger numbers (e.g. 35 degrees) and you should see something change.
