[Flightgear-devel] xml extension : frame pointer
Let me first describe the problem, and then suggest a solution. I quote from Docs/README.xmlpanel.html : when an instrument is included by reference, its root is *not* the root of the property tree, therefore aliases must be relative. The relative location of the alias' root in the property hierarchy depends on whether the alias is used in a layer, a switch or an action. In lieu of snappy mnemonic, please use the following table. when alias is used in go up - - layer 5 ( ../../../../../params/foo ) switch 3 ( ../../../params/foo ) action 3 ( ../../../params/foo ) That reminds me of assembly-language programming on a machine designed in the 1950s. (In contrast, by the 1960s they had invented base registers and double indexing.) Do I really have to count, by hand, the depth of the xml statements, in order to know how many .. levels are needed? I thought computers were supposed to be good at counting stuff. Here's a modest proposal: Define a notion of module. In the simplest version a module is a file, such as a *panel.xml file (although fancier notions of module are certainly possible). Then define a new entity called the base register or frame pointer. It is denoted ... and points into the property tree, somewhat the way . does, except that ... is always automatically bound to whatever . was /at the very beginning of the module/. Therefore in a typical *panel.xml file, it would be possible to write simply .../params/foo and the programmer would not need to do any counting. This would make the code -- easier to write; -- easier to read; -- more portable and reusable; -- more maintainable; and -- more elegant. There would no longer be any need for a snappy mnemonic. To say the same thing another way, counting up from the frame pointer is nicer than counting down from the stack pointer. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Flightgear-devel] Aircraft design idea: Cirrus Jet
I had a rare chance on wednesday to go up to Cirrus Design and get a tour of their facilty and see how their aircraft get put together. This was an extremely fascinating trip. In addition, they just happened to be unveiling the mockup of their new personal jet design to the media on Thursday (yesterday.) I got to see it a day earlier, even before the folks that have plunked down $100k to get on the waiting list got to see it ... but all the employees got to see it before me. The Star Tribune ran a story with an actual picture of the mockup: http://www.startribune.com/535/story/1275392.html I have some questions about some of their design choices, but hopefully they'll be able to work everything out to get a really nice flying package by the time they go to production (still a couple years away.) So let's say that we could find out the engine choice and get thrust numbers. Let's say we know the approximate (or target) weight. Let's say we know they want it to cruise at about 300 kts, let's say stall speed will have to be in the neighborhood of 60 kts. Some of these are constrained by FAA requirements for a single engine aircraft, so we can make pretty good guesses. I think we could come up with a very plausible flight dynamics model quite quickly. The jet has a very pleasant outline and now that they've gone public with the look, I think it ought to be fair game to model. We don't have anything quite like it in our stable. A small, quick personal jet with slick lines would be a lot of fun! And since it doesn't actually exist yet, you can WAG at a lot of the specifics and have some fun with it, or add some of your own personal touch. :-) Just seemed like a neat/fun idea if someone out there is interested ...

The Very Light Jet market is quite booming since 2005 (with the introduction of the Eclipse 500), and various manufacturers ranging from major players like Cessna (with the Citation Mustang) to Honda (with the HondaJet concept) are developing light jet-powered aircraft with a price tag of around $1 million, which would be in the range of the more wealthy general aviation owner. Most of these aircraft feature state-of-the-art systems and technology and a lot of the aircraft in development are under a corporate blanket so there is little we can do there. The E500 is one of the few aircraft that is already on sale and most of its performance data has already been disclosed. I like flying these small corporate jets since they're easy to handle and still offer a lot of power and range. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Flightgear-devel] Overlay Plane

I've used other OpenGL based systems with this feature but don't know where to start with implementing it in Flightgear.

I was thinking that a nice project for someday would be to get some video frame grabbing hardware and be able to capture video frames and convert them to opengl textures. I've seen this done in only a few lines of code once you get the byte ordering and various graphics formats issues figured out. I don't know, this might even be possible with a cheap usb web cam? Once the frame is converted to an opengl texture, then it would be a very simple matter of displaying it on the screen with a textured rectangle drawn in immediate mode ... possibly with some level of transparancy, or not ... I'm involved in some UAV research where we are using FlightGear to render a synthetic view from the perspective of a live flying uav. Would be really cool to super impose the live video over the top of the FlightGear synthetic view. Or super impose an F-16 style HUD on top of the live video ... I have lots of fun ideas for someone with a fast frame grabber and a bit of time. :-) If someone can tell me how to do frame grabbing on a gumstix ( www.gumstix.org) I'll offer you my 3rd born child (should an accident ever happen.) :-) Regards, Curt. -- Curtis Olson - University of Minnesota - FlightGear Project http://baron.flightgear.org/~curt/ http://www.humanfirst.umn.edu/ http://www.flightgear.org Unique text: 2f585eeea02e2c79d7b1d8c4963bae2d - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

[Flightgear-devel] Real life pilots Fokker F50 instrument panel project
Hi, as probably only a few experienced aircraft-/3D-designers regularly read throught the official FG Forum I want to draw your attention to the very interesting Fokker F50 3D instrument panel project of a real life Fokker F50 pilot (FokkerCharlie). He seems to be really engaged, has already made a lot of nice instrument/panel digital fotos (see link at the Forum) and wants to learn Blender as he still is a totally n00b. AJ already gave him some advice but cannot go into the work himself. After my opinion a cooperation of an experienced FlightGear aircraft or 3D designer with this guy could result in an outstanding aircraft - the big value is that he has access to the aircraft and the pilot's handbook and has all the knowledge an aircraft designer normally does not have (we know all the positive exceptions from this list :-) ). And beside this, he should know how the real Fokker F50 should behave realistic in a flightsim and therefore an improvement of the flightmodel could be done. So sharing the workload between someone who already knows how to make an working 3D panel and FokkerCharlie with his hands on the aircraft - what could be better for a *very realistic* small airliner?

Difficult to answer, just this, which has been written : =About the only significant short coming of the Lightning was spin/.stall recovery, which could be a bear, especially at low altitude.

Wheter this is done by brute force or if the servos can sense that they are being overpowered and then let go, I don't know. Since we don't have any force feedback support in Flightgear, we'll have to make the autopilot sense that it is being overpowered. The hard part will be how to decide that the pilot is trying to overpower the autopilot. One possibility is to press a button to tell that you are overpowering. My guess is that it probably monitors the integrated term in a PID controller, and disengages when the value reaches a certain threshold.
