[Flightgear-devel] Broken ATIS Init due to late OpenAL Initialization.
Greetings, In Flightgear 2.0 and CVS on Gentoo linux, ATIS transmissions were not working properly. Upon examining the code, I noticed that ATIS was initialized in the fgIdleFunction with all the other subsystems, yet fgInitSoundManager() isn't called until inside the main loop. Since ATIS is setup before OpenAL, when ATIS attempts to load the default.wav file, it fails when it hits the if(!_working) trap in the audio load function. I have worked around this problem by spamming the #ifdef ENABLE_AUDIO_SUPPORT block of code from the main loop into main.cxx just before fgOSMainLoop(); is called. This init's OpenAL before the other subsystems. I'm aware that this is an awful and piggy solution and am willing to write a proper patch, but I don't understand how sound init is supposed to work, where, and when. Hope this helps someone, I've seen s few unresolved reports of this issue around on the 'net. Cheers, Zeb McClure -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Re: [Flightgear-devel] Shader question
There is also another approach to creating normal maps, using a detailed, high polygon count model of the object, from which you extract the normals and map them to the low polygon object which is used in the game. A nice tutorial for blender can be found here : http://blenderartists.org/forum/showthread.php?t=138194 These are very generic instructions for normal map baking, I didn't try the FG shader yet, so I presume this may need some tweaking, specially regarding the normal space to be used. See http://wiki.blender.org/index.php/Doc:Manual/Render/Bake for more details about normal space. This normal map shader work will be a huge step ahead for image quality in FG, congratulations !

[Flightgear-devel] lamp-post appearance depends on camera tilt angle
1) I closed the bug-tracker issue concerning the taxiway signs. That's all good. 2) Alas there are other scenery elements that still exhibit an improper dependence on camera tilt angle. Example: http://www.av8n.com/fly/fgfs/img48/pole-dark.png in contrast to http://www.av8n.com/fly/fgfs/img48/pole-red-white.png In particular, look at the lamp post just to the right of the tan building, directly above the aircraft compass. Its appearance changes dramatically as a function of camera tilt angle. Note that I have gone to some trouble to control for variables that might _properly_ affect the appearance. The illumination is not changing, and the point-of-view location is not changing. Only the camera tilt angle is changing in the example screenshots cited above. Object appearance should not depend on this. I don't have any first-hand understanding of what's going on, but it is easy to hypothesize that the lamp-posts are afflicted by the same disease the afflicted the taxiway signs. Or not. In any case, this is a definite opportunity for improvement, since the unstable appearance is quite noticeable to pilots who are just taxiing along, minding their own business. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
