He just seemed to have looked over the code and *did* try some workarounds for the HUD symbols to end up in the scenegraph. Which doesn't sound like mutual exclusive work to me. OK, but how should I go on with the broken F16 tape?! Mathias will probably change that anyway, so is it worth spending time to fix it now? To make that clear: I very much agree with Mathias plans, at least so far as I know them. Putting the HUD elements into the scenegraph is certainly a good thing. But I don't know how HUD items shall be drawn after that. Not directly with gl* drawing commands, but how else? By moving textures around? This will never allow the flexibility that we currently have. Or by just using line drawing wrappers that can easily be switched from plib to osg or anything else, but basically do the same that they did before? In the latter case fixing the tape would be worthwhile, in the former not. m. Using Tomcat but need to do more? Need to support web services, security?

No, no. You misunderstand. I know, of course, what the problem is. The old tape scales were only done in the integer domain, and the tick mark positions were found with the modulo operator. This doesn't work with floats. I do now either have to scale that back into the integer domain, or use a different mechanism. I know well how to do that. I just don't know if it's worth at all.

(I simply turned off torque calculations. Doesn't matter on that model anyway.) If you put the stick forward or backward there should be a yaw effect. With the bugfix you have to cancel the torque generated by fuselage and airspeed by putting the stick backward. This could be the cause for the yaw. (Or dou you get the yaw moment with torque off?)

This lands somewhere at the height of the rotors (fwd Z: 2.6, aft: 3.99).

Making it 110 degrees will tilt it 30 degrees to the right of vertical, but (and this is important) the up/down sense of its flap surfaces will be reversed. Andy OK, there are no flap surfaces, but it is an asymmetric airfoil. The upper part of the airfoil faces left and a little down, producing right yaw and a little pitch up in forward flight. I think it also has some incidence. I should be able to make this work, starting by making the dihedral 70 deg. It's all academic at this point though, since wings are ignored on helos ATM.

To make that clear: I very much agree with Mathias plans, at least so far as I know them. Putting the HUD elements into the scenegraph is certainly a good thing. But I don't know how HUD items shall be drawn after that. Not directly with gl* drawing commands, but how else? By moving textures around? This will never allow the flexibility that we currently have. Or by just using line drawing wrappers that can easily be switched from plib to osg or anything else, but basically do the same that they did before? In the latter case fixing the tape would be worthwhile, in the former not. I am not sure about that. That depends on what they really do. And I doubt that I will be really sure about that without a cleaned up codebase. The velocity vector for example is something that can easily go directly into a leaf node that is just transformed by some properties that may not yet exist. Some text elements that can be reused for several things can be implemented with some leaf nodes. Some ladders can be implemented with a fixed part and a movable arrow part. A scenegraph can be looked at in an other way to factor out some commonly used elements. As a first step to factor out something I tend to clean up things. That is at least my way of doing this. Anyway, the more parts we can sensilbly factor out into small modular chunks, the fewer parts must be reimplemented when we put an other scenegraph below that code.

Something similar is already in render_area_2d.cpp. On top of that base implementation, a library of hud primitives can be provided. I believe that many parts that are useful for a hud can be reused for mfd's. The key is that the base implementation might move into a scenegraph dependent simgear directory. The hud parts just use them. I can think of a thin layer around the opengl calls to paint lines, line strips, triangles, quads and such. That wrapper should also manage how state changes need to be done so that there is a minimal set of state changes and that the scenegraph is aware of them. Does anybody have directx experience how such simple primitives are rendered in immidiate mode? To see if this path is worthwhile, it would be good to see the cleaned up code ...

I set /autopilot/settings/passive-mode to true but it appears thats not enough ... Thanks in advance , if anyone knows the answer. I won't say this is the best way I could have implemented this feature, but here's the logic. For controlling a flight director you want something analogous to a running autopilot that is not driving the servos. This is similar to a cascading controller where the final stage is disabled. For instance an altitude hold mode could be implemented in 3 stages. Stage 1 sets a target climb rate based on your altitude error. Stage 2 sets a target pitch angle to achieve the stage 1 climb rate. Stage 3 drives the elevator trim to achieve the the stage 2 pitch angle. In this example you want to run the first two stage and disable the 3rd/final stage which actually manipulates the elevator. To achieve this you need to add a tag to the enable block in a stage definition in the autopilot xml. This will look something like: enable prop/autopilot/locks/heading/prop valuedg-heading-hold/value honor-passivetrue/honor-passive /enable What this says is that when passive mode is enabled, this stage will be ignored. Any stage that doesn't have the honor-passive tag in it will always run as per usual. Syd, I can send you my personal testing autopilot config for the Bravo if you like. Or, why don't I just waste some bandwidth and attach it here. The nice thing about this approach is that you get nice target pitch suggestions for the flight director. I also have a perl-tk test control head with the KFC-200 buttons and annunciators if you are interested in that at all.

Re: [Flightgear-devel] A couple quick movies
I've been playing around with some scripts to leverage the autopilot to chase ai/multiplayer aircraft and also some script to control the lead ai aircraft in various ways. In the process I snapped a couple short movies with my digital camera which I thought turned out pretty cool, so I've posted them on the FG web site to share. These are all of a target AI aircraft being chased by a piloted aircraft (possibly under autopilot control.) 1) How did you set up the camera viewpoint, and 2) how do you publish the location of the AI aircraft?

These are all of a target AI aircraft being chased by a piloted aircraft (possibly under autopilot control.) 1) How did you set up the camera viewpoint, and 2) how do you publish the location of the AI aircraft? 1) This is just a standard/default viewpoint. Press v/V to cycle through the different views, for each view you can move the vantage point (or view direction) around with the mouse. 2) The location (and much more) of all the AI and most (many) [1] of the multiplayer aircraft can be found in /ai/models/aircraft[n] and /ai/models/multiplayer[n] I added a flag (cvs) to allow you to force radar computations on all the time so you can always have range and heading/pitch offset to each target. You can also get speed, orientation, position, etc. For ai aircraft without a flight plan, you and direct their target speed, altitude, roll, heading, etc. through the property system. The ai system has a very simplistic/minimalistic dynamics model for aircraft, but it's just enough to make them behave plausibly when viewed from a short distance away ... in other words, they all look like they are flying, even if the full physics model isn't being computed for them. [1] I think their may be a bug in the multiplayer system where nearby aircraft aren't always registered in the property system.
