Re: [Flightgear-devel] Scenery not being loaded
Figured it out. Per the Wiki instructions for installing terrain, apparently you can't just download scenery into the $FG_ROOT path (it's still not clear to me why not). I have a new problem, now, though. I do see the scenery (when I get under about 6000 feet - until then I see only white fog) since I gave the path to the directory outside $FG_ROOT where I placed the terrain, but now I no longer get proper HUD symbology - the numbers aren't there anymore. Any suggestions on how I can do this? I'm not sure how I can set two scenery paths on the cygwin command line for starting FlightGear. Jon > -Original Message- > From: Jon S.

[Flightgear-devel] flight recorder / replay system
I have updated the flight recorder / replay system with something I had already planned after last year's update. Two new features: 1. Sessions can be saved to/loaded from disk. Simply fly along, then select "Save flight recorder tape" from the file menu and press "Save". You can load the tape again at any later time. You can keep the tape recording for your own amusement - or send it to someone else. 2. You can add text messages to a flight recording. This turns the recording into a flight tutorial. It's somewhere in between the existing tutorial system and a Youtube video: unlike the existing tutorials, the recorded flight can be used to demonstrate complete flight manoeuvres, such as how to fly a complex approach into an interesting airport. And unlike a fixed video tutorial, users can change views, inspect instruments, or take over control at any point. As a teaser and test, I have created a tutorial showing how to fly the nice "Isafjördur fjord" takeoff and approach. A beautiful airport in Iceland. The tutorial should be used with the Beechcraft b1900d: Instructions: - Make sure you have (terrasync) scenery for Iceland (airport "BIIS"). - Download tutorial and store on your disk: http://www.filedropper.com/b1900d-biis-isafjordur-tutorial - Start FlightGear with the b1900d. - Menu "File" => "Load Flight Recorder Tape" - Select the downloaded file "b1900d-BIIS-Isafjordur-Tutorial.fgtape" - Press "Load" - Watch. You should also see instructions during the flight. - Try the approach yourself (i.e. go back with the replay slider, press "my controls"...) (The "cool" Icelanders fly this approach on daily schedule. For the interested, here's a real-life recording: http://www.youtube.com/watch?v=Fv_c6vA8DXE ). Never mind the scenery glitch at the airport (in the FG scenery, not on the RL airport ;-) ). I'll document the details of how to create a tutorial (add text messages) later. For now, I'd like to know if the basic system is working everywhere, and if recorded "tapes" work across systems. When something is (not) working, let me know. cheers, Thorsten -- Everyone hates slow websites. So do we.

Short answer: No. The changes just affect random number seed generation. -Stuart -- Everyone hates slow websites. So do we.

Don't wait for me. Anyway, sun direction and colors are given to shader via normal uniforms that are updated here (in Rembrandt mode only) : http://gitorious.org/fg/flightgear/blobs/next/src/Viewer/renderer.cxx#line1570 Moon equivalent should go the same way. I just don't have an idea on own to balance sun light and moon light without knowing the time of day or having test on the light direction. I suspect the difference in light intensity (dynamic range) doesn't fit in an 8-bit 3-component color. I was also thinking about replacing sun values by the one from the moon during night in the C++ code, without telling to the shaders. I didn't ponder on the cons of that approach thought.

Thanks, that was what I was hoping for :-) It depends a bit on if Fred wants to do anything with the moon - my scheme would be fine with the angle of the moon above the horizon and the moon phase (or, as Curt explained, equivalently the relative angle between sun and moon) as properties. I think I have a brightness curve of moonlight as a function of phase somewhere, so from there I'd be good. However, if we want directional moonlight in Rembrandt, then I guess the info has to flow to the shader in a more direct way (like gl_LightSource[1].position) - in which case I'd use it from there. * Thorsten -- Everyone hates slow websites.
