This sounds very promising :-)) Quick question, since I'm about to process and index another voice recording, will this remove the 8KHz, 8bit limit?

Originally I modified SGSoundMgr with some success but have dropped that idea and am currently adding SDL audio support to plib.sl. This approach is much more promising and requires minimal changes to FlightGear.

Around about line 748 of main.cxx, btw One would think so, but I guess am not smart enough to do this i.e This nor anything else I have tried doesn't work // We can do translucent menus, so why not. :-) // Force Poly Fill mode glPolygonMode(GL_FRONT, GL_FILL); menus->apply(); glBlendFunc ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA ) ; puDisplay(); Regardless we still want a key binding as normally you want to switch back and forth between textured and wire-frame to get your bearings Cheers Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

IMO yes in that this is also handy for developing/debugging geometry in general in that you can see shadows < ie face orientations > much more clearly without texturing applied > As far as shading is concerned, the scenery is always flat shaded and the > models are always smooth shaded. Probably, but this could also be a toggle. Cheers Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

The functionality should still be there, you just have to tweak the property via the property broswer or telnet interface, etc. Once upon a time there was a command line option, but I think that got lost along the way somewhere ...

Yes and No. If you want to show your scenery in FG untextured, you'll need some color information. (fgsd always show the scenery untextured ) Using the same default color for all kind of material (except the few that have a special setting ) will give you a rather boring landscape. -Fred ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

Huh ?? Hmm.. I guess you are correct, but I don't remember any discussion on this and IMO being able to toggle between flat-shaded, wire-frame and textured display modes just' make sense' and is a defacto standard in any reasonably sophisticated OpenGL application. This is especially true in one with as complicated a display system as FGFS as this iis the only means you have to visualize what is going on behind the 'scenes' as textures just hide the details. Since this is just a 'mode' swap this is pretty straight forward to do and should only hve to be done once at the start of the loop hence doesn't carry a performance penalty If there was some discussion as to dropping this basic support could someone pont me to it please.
