[Flightgear-devel] Fgrun output to fgfs
I would like to make a small mod to Fgrun, I would like explore the options of making it drive fgfs multiple machines rather than just one. I spent some time studying the code today and it looked like it runs fgfs as a child process from the run_posix module. Am I on the right track with this assessment? Possibly the best way might be get it write a file rather then do the rest from a script. -- Regards Harry -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.

[Flightgear-devel] Small fgrun 'bug' re Atlas
Hi Fred, As previously stated, thanks for the great WIN32 installer v20110207 ... it works like a charm ;=)) But it seems fgrun adds Atlas - --atlas=socket,out,5,localhost,5505,udp by default, which is not really a problem. But then when you check the Atlas option it adds a 2nd Atlas command - --atlas=socket,out,5,localhost,5500,udp or as you configure it... And when you then uncheck the Atlas option, it removes the 2nd, but not the first Atlas line from the command. How to remove the 'default' Atlas line, if you want no Atlas 'connection'?

Re: [Flightgear-devel] Fgrun output to fgfs
Hey Thank you Frederic, I get the gist of your message, I point fgrun at a script that will accept the argument string, sort out the options then fire of relevant the command to the various machines. i am all for having a custom script to deal with these unorthodox setups than needlessly tinker with code I don't fully understand. Obviously in a multi machine setup I don't want any io and video options passed but the receiving script can be set to filter with that kind of thing. Would I need to fake fgfs back to fgrun with this script? Or just let the script do its thing and exit normally once its kicked off the various machines. Fgrun then just thinks fgfs terminated normally, albeit rather quick? I suspect in a multi machine setup this is best but the script could hang around till the master machine with the sim engine exits.

Re: [Flightgear-devel] Sinking feeling - c172 on gravel runway
Correct. JSBSim itself makes no distinction between ground materials (hence the reason why some aircrafts are able to land on water). This can however be managed with Nasal scripts.

By the way we can play with the gear Z position (gear/unit/z-position) and the well known terrain nasal script (geodinfo) which expose the terrain load-resistance.

Hi, RE: http://www.geoffair.net/tmp/tilted-001.png Thank you. All good points... Am presently Terrasync e000n40 so I can try the Grass (3) at LFPZ Saint Cyr l Ecole, where I am sure I have seen this tilting back several times before... Also, it does not happen EVERY time, in each of 3 machines, 3 OSes... but when I get the situation, it seems very repeatable... It happens after the begin fade of the splash screen, and the first view out of the a/c always seems flat and level... If it is going to happen, it is after a second or so, then slowly over the next 4-5 seconds... up to about 5 degrees, but can be less... Sorry, all just guesses at this stage... and have yet to try other a/c...

Re: [Flightgear-devel] Near Clipping in the virtual cockpit: please help!!
Hi Paul, Here is an interesting link that explains the core of the problem. http://www.sjbaker.org/steve/omniv/love_your_z_buffer.html It's been a while, but one technique for dealing with this is to clear the zbuffer and reset the near plane location when drawing different portions of the scene. This can work well if you can divide up your scene into stuff that is further away (like terrain) and stuff that is closer (like the cockpit) and then carefully pick the order you draw the different portions of your scene graph.

Re: [Flightgear-devel] Sinking feeling - c172 on gravel runway
Hi, Re: http://www.geoffair.net/tmp/tilted-001.png Again, thanks for the multiple inputs... 1. __tailwind__ (a) John, I wanted to try your metar to see if it looked related, but like Arnt I can not get the metar string through the command parser! Always - Fatal error: Failed to open file at 012345Z (received from SimGear XML Parser) What are we doing wrong? I tried, like you and Arnt put - --metar= 012345Z etc then --metar= 012345Z etc even '--metar= 012345Z etc' --metar=' 012345Z etc' Always the same error message and fgfs aborts...

From what Henri said, it certainly seems possible that nasal is dickering with the gear Z position (gear/unit/z-position) ..., or something, so more to explore here... I can see in c172p/Nasal/action_sim.nas that it, in the update_actions function, gets lots of gear related nodes like - var dhN_ft = props.globals.getNode(gear/gear[0]/compression-ft, 1); var dhR_ft = props.globals.getNode(gear/gear[2]/compression-ft, 1); var dhL_ft = props.globals.getNode(gear/gear[1]/compression-ft, 1); var propGear0 = props.globals.getNode(gear/gear[0], 1); var propGear1 = props.globals.getNode(gear/gear[1], 1); var propGear2 = props.globals.getNode(gear/gear[2], 1); var nose_link_rot = propGear0.getNode(compression-rotation-deg, 1); var left_main_rot = propGear1.getNode(compression-rotation-deg, 1); var right_main_rot = propGear2.getNode(compression-rotation-deg, 1); and later sets the latter 3 to calculated values... At the end sets itself up to repeat on each frame - settimer(update_actions, 0); And ties itself into - setlistener(sim/signals/fdm-initialized, init_actions); and setlistener(sim/signals/reset, init_actions); H... can not yet see where the r/w 'surface' is in this, but some things to try here, to at least rule out this particular nasal, like comment out 1 or all of - nose_link_rot.setDoubleValue(theta); right_main_rot.setDoubleValue(right_alpha_deg); left_main_rot.setDoubleValue(left_alpha_deg); But out of time today, but will be back tomorrow, after eating and sleeping on it...

[Flightgear-devel] SimGear bug? read-only properties tied to object methods not initialized
Hi all - here comes a tricky one:
(good bugs are usually tricky - not everything tricky is necessarily a bug)
Imagine an arbitrary PropertyList config file like this:
PropertyList
foo type=double3.14/foo
/PropertyList
and a code fragment like
class MyClass {
public:
double getter() const { return foo; }
void setter( double d ) { foo = d; }
void dosomethingfancy();
private:
double foo;
};
void MyClass::dosomethingfancy()
{
someBaseNode-tie( foo, this, MyClass:getter, MyClass::setter );
}
Ignore the fact, that it doesn't make much sense here - it's just an example.
One would expect that foo in MyClass (and the value of the thereafter tied
property) gets initialized to the value of foo from the config file which is
3.14. This actually works fine.
Now, modify the xml file to look like this:
PropertyList
foo type=double write=n3.14/foo
/PropertyList
(note: foo is now read-only)
The value of the foo-property now remains at an unchangeable value of zero, it
no longer gets initialized to the provided value in foo. That is because the
property is declared read-only and the setter method never gets called.
In simgear/props/props.hxx in SGPropertyNode::tie() some code exist to set the
value of a property after being tied, to the default value using setValue().
However, setValue() is smart enough to check for a read-only property and
refuses to change a property value in that case.
A fix might be to temporarily set the WRITE-flag for the property in the tie()
method like this:
(fragment from props.hxx, SGPropertyNode::tie(const SGRawValueT rawValue,
bool useDefault), line 1789ff
if (useDefault) {
int save_attributes = getAttributes(); // save current write-flag
setAttribute( WRITE, true ); // write-enable the property
setValue(old_val); // set the old value
setAttributes( save_attributes ); // restore write-flag
}
instead of
if (useDefault) {
setValue(old_val); // noop for read-only property
}
Comments?

[Flightgear-devel] Blender question?
I have a hopefully quick question. I've generated a 3d model mesh in ac3d format. I'm doing this from a perl script and I posted some pictures and details of the actual model here: http://www.flightgear.org/blogs/curt/uas/misc/3d-modelling-with-perl/ My script just generates the left half of the model. I assumed I could just import this into blender, duplicate the half and mirror it and produce the whole model. I'm new to blender, but I managed to duplicate the side and mirror it and the mesh looks perfect. My problem is that when I export the full model, the mirrored half is black from the outside. When I look inside of it, it's shaded properly. It appears that when I mirrored the surface, the face ordering didn't change so the mirrored half is inside out. I've been trying every possible face/normal/edge option I can find in blender and haven't been able to figure out how to get my faces back the right way. The original half of course looks just fine. It's probably something super simple, but I've googled and haven't found the right set of keywords I guess. Is there an easy way to get all my faces the right way so both sides of my model are right side out and look correct?

At that point the part that is black from the outside should become transparant from the outside. Then you need to flip the normals for those faces. You might be able to do this by using normals recalculate outside in edit mode. When you are in Edit mode in the 3D part of the display you should be able to activate the buttons menu in the other part of the screen and it will allow you to turn on displaying the normals vectors in the 3D screen. This will let you know for sure which way the normals are pointing.

I'm no blender expert but what I do after mirroring is selecting the
faces of the mirrored part and flip the normals ('w'-flip normals).
There used to be some apply transformation command (alt+a?) but I have
not managed to find it in recent times.
OTOH for your model you could also add the mirror modifier to the
orginal half and leave it to the AC3D exporter to actually mirror the
mesh - that usually works without problems.

Another useful trick is to click 'show normals' - you'll then see a small blue line extending from the centre of each face in the positive direction - if the normals point inward then they need to be flipped.

Re: [Flightgear-devel] Blender question?
Curt, To add to what Anders and Chris have said: Mirroring an object reverses the order of vertices in faces, which results in polygon normals pointing in the opposite direction-- outside becomes inside. If you're mirroring in Edit mode, you should only need to do the flip normals command. I.e., with the mirrored elements selected, hit the 'w' key and select 'Flip Normals'. After doing this, consider selecting everything and doing a w-Remove Doubles. This will take your two halves and create a single unified whole, eliminating overlaping edges and vertices, which helps avoid unwanted seams when rendered. Anders mentions the ctrl-a command. When mirroring an object in Object mode to create a second object for later merging with the first, it's a good idea to select the mirrored object and hit ctrl-a-Scale and Rotation to ObData. Blender keeps a stack of modifying operators on an object, but isn't perfectly consistent about considering stacked operators. This can yield unexpected results when mirroring and flipping normals. So I recommend using the ctrl-a command at the object level to apply and clear operations to the object, then go into Edit mode and do the flip-normals thing. It can save you some headaches, particularly if an object seems stubborn about being inside-out when exported. -Gary, aka Buckaroo On Thu, Feb 10, 2011 at 4:55 PM, Curtis Olson curtol...@gmail.com wrote: Hi Chris, I turned on normals and they are all pointing outwards on both halves of my model.

Re: [Flightgear-devel] Sgtext
Thanks guys I'll look through those examples... The reason I need to split the altitude is the PFD display scrolls less than 100 values in steps of 10 and in smaller text. 100 and greater digits are larger non scrolling text ... easy to do with textures and textranslate, but I'm attempting a 3d text only version if possible. The zero and space padding works here , and precision below the decimal point. I still suspect I,ve got an error further up the xml file , just can't see it.

I don't think I've had to use scaling on any text values though. S.

The property scale and offset don't work here , and formating doesnt behave like I expected ... for example , format%2.0f/format for altitude at 3029.23341234 prints 3029 . Scaling the property by 0.01 prints the same. Are there any working examples I can compare with ? I'm also wondering if it's an OSG error, (2.9.10), but I'm not to familiar with Callbacks the text code has several if(numeric) checks , but I can't figure out where numeric is set . Thanks in advance if anyone can shed light on this. Syd -- The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
