[Flightgear-devel] Possible Scenery bug

2006-04-29 Thread George Patterson
I noticed as some other have also that flying from KSFO to KSFO via vor
VTU results in a crash.

After Pigeon looking at it it he noticed that setting --vor=VTU at the
command line will result in the following error message ebing repeated
serveral hundred times. This applies for KSFO, fgfs loads fine at KOAK.

radius = 0 ! 


Finally, yasim find a soltion: 
...
radius = 0 !
  Trim Results:

But then shows the following warnings (also repeats):

The menu bar does load but are slow to respond. The terrain outside is
doesn't show up.

I spoke to Pigeon on irc who commented that it could be a scenery issue
problem near that Vor.

Two good seeds. :)
BitTorrent works really well if there are enough people who will carry on 
seeding after they have finished downloading.
In small releases like ours people tend to grab and then disconnect which 
doesn't help much.

Polygons aren't the issue; textures are.  So, feel free to go ahead with 
15,000 polygons. :)

If you have a look at 747-autopilot.xml you'll see that for each 
autopilot mode/function there'll be one, or more, 
pid-controllers.  These need to be tuned to match the flight 
characteristics for each specific aircraft.

The poly count isn't that critical for a single object.
Even the 2+ poly Concorde will have little effect on an old Geforce2.
It's when you try to place 1 of those high poly count objects in a small 
area of scenery that you run into problems.

I could post your iso file on my ftp site (ftp://kingmont.com).

Flightgear is already "mirrored" there, and Curt has the ability to upload
to that location.


I'll create a "fglive" directory there.

The F-14 has a rather complex geometry so I'd say you are supposed to

I can't give you numbers, but the fewer the better.

Especially with a fighter plane that you might see during a dog fight
it's crucial that the frame rate stays up.

So I sugesst that you use LOD heavily.

Having a high poly model for looking at it on the runway is great. But a
low poly model that you'll see from a short distance (i.e. the dog
fight) is also important.

CU,
Christian

Just one question before I get started ...

 What is the "reasonnable" polygon count (in triangles or quads) that can be 
accepted by most platforms without turning into a slideshow ?

For strike fighters this is somewhere  in the 10,000 range (with a damage 
model).

 I have come to realise that an iBook with a power PC G4 at 1GHz (the thing I 
am using to write this mail) is rather
slower (understatement) than my other box (Linux box Radeon 9600Pro and 2 GHz 
Athlon).

 I can make something quite pretty with 7000 to 8000 polygons (given that the 
tomcat has quite complex shapes)
With 15,000 polygons it can be really great...

Yes, I just now found the link page at the JSBSim site :(  I guess I haven't

damping.

I just used aeromatic to generate an A-4 model, then went through and changed 
the pitch stability derivatives to match those in the Teper paper.  I'll work 
more on it later, but right now I just wanted a model that puts Teper's 
"official" numbers into the pitch calcs.

A short test flight shows an airplane with very light pitch damping, as one 
would expect.

It seems that in the pitch channel for the A-4 the pilot commands normal
acceleration. The Az error is computed, and that is differenced with pitch
rate. That error drives the elevator. See the A-4 section here:

The mach dial rotates based on pressure altitude using the property 
/instrumentation/altimeter/indicated-altitude-ft see 
https://ewhdbks.mugu.navy.mil/mach-as.htm .

The scale is calibrated so once the dial is set for a given pressure
altitude it doesn't need to move until the altitude changes.  

See the file Models/asi.xml its already set up.

The handling of PLIB/SSG should be very easy. Just cull and draw the
scenegraph from the "virtual eyepoint" first and then do the normal cull
and draw that we are doing now.

The bigger problem is the render to texture part - but IIRC that's

AFAIK yes. This gives the pilot a much greater area he can look at.

Re: [Flightgear-devel] F-14 anyone?

2006-04-29 Thread Robicd

The usual way (the only one?) to create mirrors is to render the scenery
(at least) twice.


I wonder if it's easy to implement, I don't know how SimGear/Plib handle 
that (if it's even possible). That should not be a real drop down in 
performance since the mirror has a very small area to render.

Are those mirrors concave at all?

The "Remorqueur", the Robin DR400/180R typically has a mirror that
allows the pilot to look at the glider behind while towing. This is one
flavour, althogh the mirrors I have seen on such an aircraft typically
look a bit more 'elegant':

Even a simple C150 has a small mirror, but this is mounted into the
panel,

Yep, those that are towing sailplanes sometimes have a mirror. 
That should be an interesting thing for multiplayer: one pilot flying the 
towing plane and one is in the sailplane.

Hi Julien,

You mean you took off without closing the hood first? :-P

Though seriously, excellent work. I hope you are/will be caching the

The IRIX operating system contains a simple but terribly fast flight
simulator, including shadows, which features a F-14D; it's not that bad
but the panel looks totally artificial.
This was my first 'experience' with a simulation of an F-14 - in my
eyes probably the most thrilling military aircraft ever since - and I
would love to see such an aircraft in FlightGear,

Martin.
P.S.: I should say: This was almosty my first experience with flight
  simulation at all and I didn't use any other aircraft but the
  F-14D  :-)
P.P.S.: There was a Windows program that was told to be a port of the
SGI Flight Simulator; look for 'sgflight' - it might not run on
current Windows systems - or pick it from here:

I would like to do the texture and/or animation job. If I get the model
I'll do the mapping too. 

The hardest part will be the Flight Model, sweep wings, a pair of
retractable trim wings and a supersonic flight envelope. But it would be
a great addition to FG. ( I loved playing Microprose's F14 Fleet
Defender).

There was a texture problem (actually a texture path problem) :-( I overlooked
it using the ufo. Maybe you still have the sticky tag.

Loaders are changing the default global options even when an alternate one is
given, so the first ssgTexturePath was lost. This is unfortunate. Now I set up
our own as the default one. It is fixed now.

Thanks for this report.

That is the plan, but it's turning out to be a little more protracted than I

Thanks, it seems like a standard US instrument of the time, with slightly

Yes - the KC135 has the option of attaching a hose to the boom (and ours
hasn't), but I have read that there is a program to put hose pods under the
wings.
