[Flightgear-devel] MSVC error - glut32.lib
I am trying to compile FG on MSVC.net (7.0) on a Windows platform. I have been sucessful through plib, simgear and now FG is providing me with a "fatal LNK error 1104: cannot open file 'glut32.lib' ". The 'glut32.lib' file exists in the C:\windows\system32 folder... Can anyone suggest a solution or path to examine.

[Flightgear-devel] SP_FMDS
I've noticed in the cockpit.cxx file the instance of "ENABLE_SP_FMDS" and a search uncovers a trail into the fg_init, config.h, as well as into the HUD.cxx files. There seems to infer the existance of special FDM's, although they seem to be disabled or hidden. Can anyone offer any information surrounding these Special FDM's ? Do they relate to particular aircraft?

But is is meant to be fixed at the aircraft and thus rotates due to the
aircrafts velocity or is it fixed at the earth and relocated for every frame
to display?
Or the other question is: what is that hud element meant to display?
I cannot yet make sense of that.
Hi M,
The HUD element provides a visual indicator of energy within a constant
speed climb or descent thru the use of hud_ladr.cxx:
if(energy_marker) {
if (total_vel < 5.0) {
t1 = 0;
t2 = 0;
} else {
t1 = up_vel/total_vel;
t2 = asin((Vxx*Axx + Vyy*Ayy + Vzz*Azz)/(9.81*total_vel));
}
pot_slope = ((t2/3)*SGD_RADIANS_TO_DEGREES)*factor + vel_y;
The values of Vxx, Vyy, ... are called in for the JSBSim and YASim both, but
Axx, Ayy, ... are called for YAsim only, rendering the HUD element to
indicate velocity only.
As for reference plane, I'm hazy as to the effect of the frame on the
reference but would lean towards the geodedic or earth-referenced
acceleration. I
have been through the flight.cxx and .hxx files along with the
src/FDM/JSBSim.cxx and YASim.cxx and have come away with the "v_dot_local",
"Get_" and
"Set_Accels_Local" as the given terminology in the NED sections, although
these
may be in name only and not function.
To refresh the initial query; I would like to use the energy marker within
a training tool using a simple single trainer but I need 2 VOR's for
intersection identification. The PA-28 -YASim provides the energy marker and
the
c172 - JSBSim provides the avionics... hmmm...
Thanks,
Mike

Re: [Flightgear-devel] c172r-yasim solution error
The JSBSim interface, /src/FDM/JSBSim/JSBSim.cxx never calls _set_Accels_local() in the function copy_from_JSBSim(). Is it ( the call) easily added to the JSBSim.cxx code as a local fix ? I've looked at both the JSBSim.cxx and Yasim.cxx files, and although I think I see the call in yasim, the similarities are beyond me...

Re: [Flightgear-devel] c172r-yasim solution error
Can you be specific? Which accelerations are zero. This may be a bug.
hud_ladr.cxx defines:
// OBJECT MOVING RETICLE
// TYPE ENERGY_MARKERS
// ATTRIB - ALWAYS
//energy markers - compute potential slope
if(energy_marker) {
if (total_vel < 5.0) {
t1 = 0;
t2 = 0;
} else {
t1 = up_vel/total_vel;
t2 = asin((Vxx*Axx + Vyy*Ayy + Vzz*Azz)/(9.81*total_vel));
c172 JBS Axx, Ayy, Azz seem always zero where PA-28 and A-10 YASim have
values. This effectively makes t2 = 0 and defeats the pot_slope from any
value
other than Vx, Vy, Vz.

Re: [Flightgear-devel] c172r-yasim solution error
?? I would have figured the HUD symbology is FDM-independent. That would be ideal, however there seems to be a dis-connection between the EOM in the JSB models that's present in the YASim model. Of course, I'm comparing the PA-28 to the c172 models, but the PA-128 will drive the energy markers within the HUD according to model velocities and accelerations while the c172 seems to pass a zero value for the accelerations and the energy markers just hang onto the velocity vector values.

Re: [Flightgear-devel] c172r-yasim solution error
But again: it is unlikely that this model will be maintained in the future. The standard FlightGear 172 is a JSBSim model, and it works quite well. If there is something specific you need from the Skyhawk model, you might best be served by modifying the JSBSim one. And if you want a YASim lightplane, definitely check out the pa28-161. This is very well tuned (by David Megginson, who actually owns such a Cherokee) and works great. Andy A, At your suggestion, I spent this AM looking at the Cherokee / Warrior and agree it's as realistic as needed. My problem arises in the radio/nav stack where the individual VOR's cannot be set independently like in the c172, ie: the headings on each OBS are always the same. I'm looking into an instructor's aide for IFR approaches and would like to define an approach path intersection with the second vor-radial, easy to do with the c-172. To add to the confusion, I'm using the energy markers in the HUD to define inputs to the student and the Yasim FDM seems to support more HUD components than the JBS FDM... although I haven't spent too much time in the hud_ladr.cxx to find the links...

Each of the new portables has an option to average the position for up to an hour, making return to the point accurate to within 3-meters.

[Flightgear-devel] Development Platform Help Needed
Greetings, I am a graduate student in Virginia working with FlightGear towards a MS in aerospace engineering and human factors. I am trying to alter the existing HUD within FG to reflect a newly developed energy management algorithm. Ultimately, the pilot could match icons for bank, pitch, and throttle and fly an optimal path to a waypoint or runway threshold. My strengths lie outside the C, C+, and C++ environment and while I find the capability fascinating, time prevents me from pursuing this from the basic level. I am looking for help in assembling a development platform that will allow me to alter the program and review the changes. In addition, I need to trace the path from the HUD display to their origins, ie: velocity vector is driven by Vxx, Vyy, and Vzz... I need to access these origins. I realize this is a tall order, especially at a distance, but I have failed miserably with local talent. My exposure to development has been a review of the source code and toying with OpenGL in Visual C++, v 4.0, although I am open to suggestions for an alternate program. I feel confident that with an operating platform and a few gentle nudges, my ignorance would only surface occasionally. I would appreciate your thoughts, both on my path and on any guidance you might be able to offer.
