Re: [Flightgear-devel] announcing star trek runabout shuttle and questions
I thought I was done, but you know how it goes. I thought of several ideas for improvements, and managed to write the code to do it. In the latest, and hopefully final release of shuttlecraft and runabout, I have doubled the nasal code size to make ALL engine animations and sound effects act more realistic. Several other texture tweaking, and only a couple vertices errors. Also, I have added keyboard support and on-screen help, to look more finished. http://www.geocities.com/sandreas41/flightgear_aircraft.html Oh, and the smash to get thru the bandwidth door only lasted for the first hour last time... so waiting an hour from this timestamp can't hurt.

Re: [Flightgear-devel] announcing star trek runabout shuttle and questions
Hi R. Your suggestion of sub-orbital flight last month got me thinking: If my altitude is > 25 miles, will the scenery get loaded? I uncommented the debugging output in src/Scenery/tilemgr.cxx and tried a high-speed flight from Seattle to Peru or Chile (some impressive mountain range) where I flew down some valley toward the Pacific. (Ok, this is what I like FlightGear for.) :-) It worked. The tile cache seemed to work well. Later, last week, I managed to pin down when the fps goes sluggish, and it wasn't on a long flight. It is during "catching up on tile delete queue" That's what I thought might be a problem... Perhaps because it tries to catch up on too many tiles at once.

Re: [Flightgear-devel] announcing star trek runabout shuttle and questions
Hi Ampere, Actually creating a cloaking device isn't that difficult, having already experimented with transparency for the windows. I created a patch for danube runabout, and put it here: http://www.geocities.com/sandreas41/data/danube_cloak_patch.zip Press [TAB] to bring up the dialog menu to access it. or press landing gear button on joystick. (it was easiest to tap into, without rewriting the joystick.xml. But too easy to press accidentally.) It does create one side effect though, one that I may not figure out how to get around, without some help. Once the cloaking device is activated the first time, any non-textured surface with color, becomes washed out, even Grey. unless in direct sunlight. There is some effect from using Material:Transparency:alpha-property that changes something it shouldn't. Unless it is a feature I don't understand. Maybe the specularity? How can I access it to change it back? Enjoy! :) Stewart Ampere K. Hardraade wrote: > On Thursday 25 January 2007 02:46, Dene wrote: >> With or without cloaking device? > Oooh...

Re: [Flightgear-devel] announcing star trek runabout shuttle and questions
I'm personally hoping a shuttlecraft will replace the ufo. Light and maneuverable, excellent for flying close to the ground, up mountain canyons. But you probably guessed that already. ;) Perhaps the Klingon Bird of Prey is small enough to fly near the ground. If it doesn't have too many vertices and faces.

Ok, I searched the entire code base, and can't find any text like
"dynamic_view". So this returns to question #1...

Ah, yes, a little broken... but it was adequate to figure out how the emission
billboards work.
2 New questions:
Is it known that overlapping transparent textures cancel out the ones behind?
I had to keep the warp glow from overlapping any other animations, (for
example).
And, Why do large .ac files give SegFault11 and crash? when the same mesh,
saved in .3ds does load ok?
(I am no longer certain why some meshes load in FG and some don't.)
Perhaps, Does the ac format create a size limitation inside FG?
Thanks,
Stewart

Re: [Flightgear-devel] announcing star trek runabout shuttle and questions
Hi, Problem with orbital flight in FlightGear, is the scenery cache gets bogged down fast enough as it is. I believe I saw a comment about that, perhaps in the last month, that the tile cache doesn't get deleted properly. Of course, not a problem for normal aircraft, or "short" flights. The danube model may not be designed for real-world flight, and it would take me quite a while to learn how to integrate it with yasim, but with the exception of VTOL, I am quite happy with the way it flies with the ufo logic. More spacecraft here and there? :) Like shuttles flying in and out near the SFO bay bridge, just like in the movies.

Use of Nasal in XML is no different from using it elsewhere.
Here in this case you can't embed any nasal:

But you can simply use a different property and write some Nasal
elsewhere that updates that airspeed property accordingly:
/velocities/abs-airspeed-kt
In a *.nas file or elsewhere:
var airspeed = props.globals.getNode("/velocities/airspeed-kt", 1);
var abs_airspeed = props.globals.getNode("/velocities/abs-airspeed-kt", 1);
update_airspeed = func {
var a = abs(airspeed.getValue());
abs_airspeed.setDoubleValue(a);
settimer(update_airspeed, 0);
}
update_airspeed();
You may have to initialize the airspeed property or defer its usage
(via /sim/signals/fdm-initialized listener if you are using fg/cvs).

No. The ufo FDM was never thought to simulate an "actual" ufo. It's
just the scenery browser and was originally thought (by the author)
to replace the old scenery browser -- the "magic" FDM. That's why
it doesn't have any fancy features, and I somehow doubt any such will
be added for nicer UFO experience.

No. You could, of course, fake that via a dynamic_view like
mechanism. Just tilt 3D model and view. Or use an FDM that
supports it. That would be YASim.

I'm glad that at least a few people look at this stuff. :-)
unfortunately, the fgfs_animation.py is broken and waits for a fix.

[Flightgear-devel] announcing star trek runabout shuttle and questions
Hi everybody, I have been working on some Star Trek shuttlecraft and the runabout to fly instead of the ufo saucer, for 2 years (off and on). While I know most of you are dedicated to wing-based aircraft, I am sure there are others who like to fly around just for the scenery. I have finally reached a point where I can call it done, with only some flight-handling details remaining. So I have a few questions: Is there a programmer's guide to nasal and xml? How can I modify a factor-property to get only the integer? example in Models/danube.xml : material Mesh.ImpulseGlow /velocities/airspeed-kt 0.0002 doesn't work when airspeed is negative. 2nd: Does the ufo flight model have any variables I can set, to Detect the ground and stay above it? 3rd: Does the ufo flight model support vertical take offs and landings? (I see reactor jets in the harrier model, but ...) 4th: material emissions do not cast light on nearby surfaces. Are there other light sources available? 5th, an observation: It seems there is a ceiling at 262410 ft. above which, there is no black space. No, I don't expect to fly to the moon, but it would be cool to see the earth from space. ;) Screenshots and downloadable files are at: http://www.geocities.com/sandreas41/flightgear_aircraft.html My thanks to Melchior for the bo105 files to learn animation from, and for the blender-textured-lights tutorial.
