I am slightly concerned about catching all exceptions this way - I agree
catching std::exception is worthwhile, with the specialisation for
sg_exception since we can provide better logging and reporting, but I really
hope no-one is throwing arbitrary objects not inheriting from
std::exception. We used to have some bad cases of people throwing
std::string but I cleaned those up years ago.
There are still some catch(...) and catch(std::string/const char*)
around... I just wanted to make sure that no exception will every pass
on to C space, as this leads to undefined behaviour and probably also
a crash. I don't know who will use cppbind to register whatever is
needed in the future, so I think its better to throw a Nasal runtime
error than to let the whole program crash.

Re: [Flightgear-devel] Moving menus (aka, usability)
The Autopilot menu change does make sense (although there may possibly be a case for keeping such a flight-critical menu rapidly accessed at the top level?) I don't see this need. When I'm in a hurry, I use my left hand to enter a keyboard shortcut, rather than taking my right hand off the most critical flight controls to grab the mouse and navigate to/through a menu. the control key is usually one of the easiest modifiers to find on a keyboard Mhh.. personally, I'd slightly prefer the shift key over the control key for the most important two-key-shortcuts. Using one hand (remember, the other hand is on the stick;), shift enables a slightly larger range than control: I can somewhat easily type shift+5, whereas control+5 becomes a little difficult.

Re: [Flightgear-devel] procedural bridge generation
Hi Adrian, I was thinking to circumvent the Terragear toolchain completely (for now), and 'just' generate 3d bridge models based on OSM data. These could then go into the scenery DB, perhaps with a tag that indicates they were automatically generated. I _guess_ the next scenery build will include OSM roads, so the location of the bridges should be fine? BTW: I recall there were plans to including other OSM objects. Is there some progress beyond what's listed in http://wiki.flightgear.org/OpenStreetMap_import ?

Re: [Flightgear-devel] osm2city.py
James, Could the floor-plan data be pulled live from OSM servers, or does it need to be processed offline before hand? We have most of the infrastructure to pull data from web-services already in place. Currently data is processed offline before hand. Basically, it parses the OSM xml, generates a list of building outlines, discards some based on their area, simplifies the outlines, clusters them into ~500x500m blocks and different LODs, then writes .ac, .xml, and .stgs. OSM parsing is by far the most expensive, easily taking 10 minutes for 50k buildings. Once that's done, the remaining parts take maybe 1 minute in total. In C++, this would be faster, of course. Are you thinking of a terrasync-like thing here, where users get OSM buildings (where available) on-the-fly? In addition to what Stuart said, this might be quite expensive in terms of bandwidth. The OSM download (buildings only!) was ~40MB for the 25x25km LOWI area. Curt, Would this data set include airport hangar buildings as well? At the moment, the code knows only the floor plans. No streets, no runways, no land-use. But it'll certainly process such data in the future, and then could use some heuristics (some OSM buildings are labeled Terminal 1 or so) to apply terminal/hangar textures to buildings at airports. Hadn't thought of this before, but yes, this way we could rather easily populate some airports with 'semi-generic' terminal/hangar buildings. Stuart, Thanks for pointing me at fgelev. I'll give it a try. If I had a limited number of complex (as in 8 vertices per model) shared models, and place a total of 5 instances in a scene, could this be made to occupy significantly less RAM than 5 individual models? Gijs, Thanks for your comments! I'm aware that OSM building coverage is basically non-existant in large parts of the world. Street coverage is much better, that's why I also aim at procedurally generating cities just from a street network. Meanwhile, a forum user (vanosten, http://flightgear.org/forums/viewtopic.php?f=5t=17598) who's interested in exactly that offered to join forces. Since I've already invested ~3 months here and remarkably didn't get bored (in fact, quite on the contrary), I'm confident we'll get there eventually ;) I know of bob.pl, but I just cant read perl... When there are buildings, you'll often find that they are drawn as big blocks, rather than individual houses. True, unfortunately. Plus, _if_ there are many tiny individual houses, they'll kill framerate (backed by some experience with LOWI now). Appropriate textures might help here. Before I could create some sensible buildings for New York I had to add height tags; all skyscrapers were simply lacking that data. Why not simply assume a sensible distribution of buildings heights in this case? I've played with that some days ago, and found it looks quite reasonable: http://ubuntuone.com/0X0KcYJbRgUtIldtasWyMo http://ubuntuone.com/1LaEKT6pOtf6zxXItpKmPA http://ubuntuone.com/0jsCECjmKMaooP4wrHHwH7 Thomas -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.

[Flightgear-devel] osm2city.py
Dear list, in particular Stuart, please let me 'officially' announce my project osm2city.py [1,2] here. This python script takes OSM floor plans and generates 3D buildings for use with flightgear. I'm planning to develop this into a procedural city generator which would take a street network and then reasonably places (random) buildings. The ultimate goal is (obviously) to improve FG's representation of cities. It's at a rather early stage, and for the moment I prefer python for quick prototyping. BUT, I know quite some C/C++, and compile from latest GIT sources regularly. In the future, I'm definately willing to move this into FG (in one form or another).

Re: [Flightgear-devel] New features for 3.0 (?) presentation
Hi Vivian, 2013/5/7 Vivian Meazza vivian.mea...@lineone.net: Thanks, interesting. As a non-Blender user (it makes my brain hurt) the references are a bit obscure. If you get used to Blender its a really powerful tool (I have problems if trying to work with other modelling programs :P) and with using the right scripts it gets a very neat tool for creating models for FlightGear. For example for a gear scissor just add an armature with two bones, add an IK constraint to the second bone and attach an element of the scissor to each bone, and you are done. You can watch the animation in Blender and using an exporter script now it is possible to watch exactly the same animation inside FlightGear. You don't need to guess any coordinates/axes/etc. and if you modify and object you just have to export it again, without manually modifying the animation xml. Are the various axes always orthogonal? There are (currently) only two axes required. The lock-axis and the track-axis. They should be orthogonal, as the rotation is only possible round the lock-axis. Internally the track-axis is always orthonormalized to the lock-axis, as calculations always are performed in the plane normal to the lock-axis. Can they also be specified in the alternate form: axis x1-m5.1821/x1-m y1-m0.221496/y1-m z1-m0.794147/z1-m x2-m4.99208/x2-m y2-m0.114133/y2-m z2-m0.842884/z2-m /axis Currently the alternate form is not possible. The problem is that we have two axes crossing at the same center, so which of the axes should specify the center? Also the center/axis form clearly states where the center is located, which is not the case with the alternate form (the center is located halfway between the two given points). For the rotate animation the exact location of the center along the axis is not relevant, but for the tracking animation it is. Also as one would probably not create the xml by hand, using multiple notations would not gain us anything. If non-orthogonal axes are allowed they are difficult in the center/axis form in the example in the wiki. Perhaps, when you have time, the information could be consolidated in http://wiki.flightgear.org/Howto:Animate_models and fgdata/Docs/model-howto.html I will do if timer permits :) Yesterday I have added some images. I don't know if you have already seen them. Looks like valuable work to me: gear scissor links were very difficult with the existing animations. That was the initial reason for creating it. But now it is also useful for creating complex kinematic systems as can be found for landing gears and their doors.

Re: [Flightgear-devel] New features for 3.0 (?) presentation
Hi Ahmad, 2013/5/8 grtuxhangar team hohora...@gmail.com: Congratulation for the work, the team is giving a try, with one of our most complex landing gear. Though, like Vivian, we are not Blender user. However since : Currently the alternate form is not possible. We will want to define and to draw the ojects/group animation related, out of the aircraft main model, with the parent strut XYZ axis set to zero, AND only at the end to include that animated ojects/group within the aircraft main model. model nameRightGearAnimated/name pathAircraft/MyAircraft/Models/RightGear.xml/path offsets x-m-0.800652/x-m y-m0.658753/y-m z-m-0.683991/z-m pitch-deg3.289/pitch-deg roll-deg1.2528/roll-deg /offsets /model I'm not completely sure if I fully understand you, but if you want to include an animated submodel into your main model it should still work. There is no difference compared to the other existing animations. Also using the offsets transformations should work, although I have not tested it. Which makes most of the landing gears to be redrawn. I think I don't really understand what you mean. Every object is drawn once. If you include your landing gear twice, it will be drawn twice.

Re: [Flightgear-devel] New features for 3.0 (?) presentation
2013/5/8 grtuxhangar team hohora...@gmail.com: Hello, Thomas Sorry my question was not clear, and i probably misunderstood the feature. So, just a question: how do you define the main parent actuator axis rotation ? that one which trigger every other child components. I am using the normal rotate animation to rotate the main strut. Every attached hydraulic cylinder, link, etc. is then animated using the locked-track animation. For a hydraulic cylinder the piston and the cylinder housing each are animated using a locked-track animation tracking each other. For a gear scissor, a locked-track animation tracks from a point attached to the strut to a point on the axis. Two objects can be attached to the animation, allowing to animate a scissor. (The object and the slave object, are rotated such that the exactly fill the space between the two attachment points of the scissor). For the second type of animation I will add some pictures to the wiki later on. Most of them are not rotating with a pure xyz axis rotation but very often according to those alternate form (cf Vivian) . There is no difference in terms of what you can express. Both notations allow you exactly the same thing. For the animation a center point and an orientation (axis) are required to calculate the location and orientation of the rotation. Think of the center as the location of the hinge somewhere in space and of the axis as the actual orientation of the hinge. You can now either specify the position of the hinge and the orientation of its axis or (the alternate form) two points on the axis of the hinge, which are then used to calculate the center and orientation of the hinge. (If you use the alternate form the center and axis are automatically calculated from the two given points). There is no rotation that you can not describe with a single axis given by its xyz coordinates. That the point i was asking for, and the solution i was looking for. I could be on the wrong way.

Re: [Flightgear-devel] Nasal props API relative path support
Am 2013-04-15 08:12, schrieb Renk Thorsten: Using getprop on the one hand does not allow getting a property converted to a given type and on the other hand is tedious to use for more than one property, as one has to assemble the according property paths (which is definitely less efficient than using a relative method). If there is even a slight performance concern, the only justification I ever see for not using getprop() / setprop() is if you explicitly require to set a variable type. Assembling a property path by string manipulation may be in theory less appealing, but it is in practice 3 to 10 times faster than using the props module - I have made several benchmark tests, all leading to the same result. Large-scale property manipulation from Nasal is performance hungry and should be avoided if possible by using Nasal-internal variables instead, and if it needs to be done, getprop() /setprop() offer significantly superior performance. If you dig a bit in the mailing list archive, there should be a post with the actual benchmark test results. I've found a topic in the forum [1]. I've now also done some benchmarks and got very varying results. setprop is nearly always the fastest, but not always, sometimes getValue (with a relative path) can be slower. But setprop was a maximum of ~2 times faster than the other methods. I'll investigate this further to see where the time is lost. Probably somewhere while creating Nasal objects. Maybe with directly using a ghost for property nodes it will get faster. Also the methods with relative paths and set/getprop use exactly the same code on the C++ side, so the performance is lost somewhere between the props.nas module and the C++/Nasal bindings.

Re: [Flightgear-devel] Nasal props API relative path support
Am 2013-04-14 14:30, schrieb James Turner: Extend Nasal property methods to support relative paths. All methods exposed to the Nasal props module now accept an optional first parameter refering to another node by a relative path. I'm a bit torn on this change; making APIs more flexible is usually a good thing. However, the cost of property path parsing has previously shown up in profilers as a source of dynamic allocations and overhead. I haven't looked at it in detail, but why are dynamic allocations needed for parsing a property path? If this is the case we should to some profiling and rework it if needed. Historically, on the C++ side; I can believe that in Nasal the extra parsing overhead is lost in general Nasal overhead, but still, the idea of the existing API was to force you to design work 'the right way', i.e cache leaf leaf nodes as objects, instead of repeated referring to leaves by a relative path. If you just want a quick and dirty way to read one property, we have getprop / setprop - for any other use, you should be doing what the API already supported; getting a props.Node object for the leaf, and then manipulating it with no further string/path handling. At least, I would prefer that getValue and setValue did not support this, since it will surely encourage convenient-but-inefficient styles of use. (I would also be happy to extend props.nas with helpers to make the above syntactically more compact, but I think such sugar can all be done on the Nasal side) One thing I thing I want to achieve with this changes is to make the Nasal props API more similar to its C++ counterpart as this makes it easier to use if you are using both the C++ and the Nasal API. Also someday I want to refactor nasal-props.cpp to use cppbind, where I want to export as much methods as possible with exactly the same signature than in C++. Especially if using properties seldom (eg. only for initialization) the relative versions are probably even faster, as the Nasal overhead is lower. Eg. consider the following Nasal code used to initialize some module: var cfg = props.globals.getNode(/my/config/root, 1); var x = cfg.getDoubleValue(x); var do_it = cfg.getBoolValue(do_it); Using getprop on the one hand does not allow getting a property converted to a given type and on the other hand is tedious to use for more than one property, as one has to assemble the according property paths (which is definitely less efficient than using a relative method).

Re: [Flightgear-devel] Generating ground textures on the fly?
Hi James, Thank you for your input! I wasn't aware there is such thing as fgviewer. It's definately a good starting point, I will have a look at it. Oh, and if you can do IRC, I'm sure the guys in #fg_scenery would be delighted to discuss what you've done and a whole range of possibilities :) If by what you've done you refer to the OSM building generation: I haven't done rocket science yet. Just a couple of python scripts and some facade and roof textures. Clustered the buildings as you suggested on the forums and added a LOD animation, and now I get decent frame rates with impressive building coverage. I know there's a perl script around which does the same -- but I'm just not a perl guy. Cheers, Tom -- Everyone hates slow websites. So do we.

Re: [Flightgear-devel] Generating ground textures on the fly?
Hi Thorsten, Thank you, too! This becomes a performance issue eventually - see Paris (France). Random buildings scale well for memory and performance because they're numerous instances of the same building, so just the various positions need to be stored separately - a city full of unique buildings needs to store each building uniquely. The basic idea doesn't really scale well. It looks impressive, and scales well enough on my machine, which isn't really high end: i5-2500k, GT640TI. The basic idea would be: Based on landclass data and OSM roads, generate a unique hi-res texture for a few km out. (maybe using a base texture and overlays as you desribe below.) Gradually reduce texture resolution for terrain further out. (I did some rough estimate which indeed showed I need plenty of video RAM, but not several GBs.) Regenerate the textures as the camera moves. I have no idea if current CPUs/GPUs are fast enough for such a scheme. Or if there's a better way to achive this. This is why I'm asking you guys. This isn't as impressive as you think - the kind of graphics card that can deal with 11.000 unique terrain texture sheets in the scene (you need something of that magnitude, see the numbers worked out here http://wiki.flightgear.org/Procedural_Texturing#Photo_texturing ) is also the kind of graphics card which can go through millions of vertices. Terrain that is 100km out doesn't need 1m/px resolution. I'm certainly thinking of a LOD scheme here, so I won't need 11.000 unique texture sheets. + shared models with an individual piece of ground texture Well, but how does FG know how this is supposed to look? Obviously, if you would do it manually, you would blend the individual ground texture against the surrounding. This is exactly how I'd do it. Which is bad, because it means you need non-local information to get the task done. I don't get this yet: why is blending the texture against the surrounding bad, and what's the problem with non-local information? You'd also want to generate different patterns in Europe, the US, Asia,... Yes, I'd be happy to generate different patters for different countries. If the code supports it, artists will step in here. No, resolution will in fact go much down because of the memory limit. In the current scheme using a finite set of terrain textures with procedural overlays, we can achieve cm-sized resolution on ground features. Great. Can we have overlays for a finite set of buildings? In the end, if I could make a wishlist how to design the scenery rendering, I would probably separate hires sharp features like roads out and describe them via vertices and pass the informtion on landclass distribution via a meta-texture with relatively coarse resolution and build the actual textures procedurally everywhere based on the relative distribution densities of features coming from the meta-texture. Unique buildings would then need to be registered on the meta-texture in the scenery generation stage, the actual procedural terrain cover would be generated runtime on the GPU. Sounds like a good plan to me. As for the Intel graphics argument, I'm with Gene. Cheers, Tom -- Everyone hates slow websites. So do we.

[Flightgear-devel] Generating ground textures on the fly?
I've been playing with populating my home airport's area with buildings derived from OSM floorplan data. I think having many buildings in the correct place greatly improves realism over the current random buildings/sparse static models, especially when you know the area. However, now the buildings obviously don't match with ground textures or random trees. Any bright ideas how to achieve this? I know I could follow the photoscenery approach and pre-render special materials and masks for a couple of cities, but that just doesn't scale. I wonder how x-plane 10 does this? Could we generate the texture on the fly? Based on landclass and road data? I could see a number of advantages/disadvantages here as compared to our current, generic textures: + much better autogen scenery possible: many textured streets/railroads without additional scenery vertices + shared models with an individual piece of ground texture + get rid of sharp landclass borders + possibly improved resolution - eats much more video ram and CPU (but then I have 3 out of 4 idle cores ATM) - probably totally incompatible with the current terragear toolchain I know C/C++ and would be happy to start tinkering with this part at some point. But I know next to nothing about OSG, OpenGL, and shaders. Graphics gurus: is there any better way to do this?

[Flightgear-devel] Canvas reuse/restructuring
Hi, recently I've been asked by the FGRadar developers if we could modify the canvas system such that it can be reused in other applications and we can all work on a single and stable implementation, instead of a separate implementation for each single application. I think thats I good idea and I want to take any opportunity to get the canvas better and usable for more applications. As some of you have noticed I've already done some preparation work by moving FGODGauge to SimGear. Now the question is if this is the best way, and the canvas should get part of SimGear or another solution would be better? I'm not quite sure what belongs to FlightGear and what should go into SimGear instead. The canvas is something that could also be useful to other applications as it's basically just an offscreen rendertarget for 2D drawing. Any opinions? Tom -- Everyone hates slow websites. So do we.

The reason is that I've completely rewritten the original FGODGauge class and only kept the interfaces for backward compatibility.

Re: [Flightgear-devel] Displays vs Instruments
Am 2012-09-26 11:19, schrieb James Turner: I'm testing some architectural changes in the code, and have hit upon an area that's causing some structural problems. Specifically, we have two kinds of instruments: - 'computational' ones which read and write some values and model a system (steam gauges, navradio, GPWS, ) - 'display' ones which are based on RenderTexture / the Canvas and do a small amount of simulation, but contain a large amount of rendering code. I like the idea very much because most aircrafts are build like this. An amount of blackboxes and sensors are spread over the aircraft - invisible to the cockpit - which provide data. Either just raw or filtered sensor readings or more complex things with processed/interpreted data like nav, gpws, radar, tcas, etc. Some devices also require data from other instruments for being able to work (eg. tcas needs radalt, wow, ...). So we could just have the single bricks and wire them together using properties - just like in the real thing. The second part are the displays which today are mostly multipurpose and can show data in various ways from different sources. Even older steam gauges just show data from sensors - normally just limited to a specific data source. This separation would be great for reusable but nevertheless highly customizable instruments/displays.

The problem was that ShivaVG simply hasn't implemented it :) I've now extended ShivaVG to support some kind of a non-zero fill rule. It's not really non-zero because instead of incrementing and decrementing depending on the orientation of the drawn overlapping regions it simply checks if at least a single region covers a pixel. For our use cases it should be enough tough. I have also added some more performance improvements: Now the texture is only redrawn if something has changed. So if you don't change the map there shouldn't be any noticeable performance impact anymore. Also the bounding boxes are now only written to the property tree if they are recalculated. This should take some fair amount of changing properties away. With your changes to put everything into one object now zooming takes much more time. Seems like now tessellating takes much longer than before due to the amount of data in one single path. The current problem with zooming is that every position of every path gets recalculated with the updated projection, even though this isn't really needed as the projection doesn't noticeably while just zooming and scrolling around at a single airport. To improve this I want to implement some kind of one-time projected path which after the initial geographic projection only gets scaled and translated instead of completely recalculated.

[Flightgear-devel] Changing behavior of SGPropertyNode::removeChild
While searching for the reason of crashing FlightGear if trying to remove the nodes of the previously selected airport in the new Select Airport Dialog I stumbled upon a problem with the behavior of SGPropertyNode::removeChild. If you remove a child then fireChildRemoved is triggered and every listener is getting informed. The problem is that it is only called for the node being removed but for non of it's child nodes. So if you listen upon a specific node being removed and instead a parent node is being removed you will never get notified and have a pointer to an invalid part of your memory which can cause a crash :) I've pushed a commit witch recursively triggers childRemoved for all nodes controlling the canvas. Any objections on moving this behavior directly into simgear?

Re: [Flightgear-devel] Switching from PUI to osgWidget
Am 2012-07-31 10:00, schrieb James Turner:
Currently I'm copying all values to the property tree. The following
properties are set on the canvas of the active window:
mouse/x
mouse/y
mouse/dx
mouse/dy
mouse/button
mouse/state
mouse/mod
mouse/scroll
mouse/event
I don't know if it would give as any advantages to have some global
mouse states because the values are only valid for one single window
(coordinates are relative to window origin).
Hmm, I was hoping we'd be able to register callbacks on specific widgets (or
panel nodes in my case) - do you have a Nasal layer on top of these
properties to forward semantic events ('left button press', 'scroll up',
'double-click') to Canvas elements?
mouse/event contains the type of event (its a
osgGA::GUIEventAdapter::EventType) and is always updated last, so it is
enough to just register a callback on mouse/event and read all the other
properties.
The advantage of just using properties is that you can easily create
mouse events from different sources, even from Nasal (eg. to control the
cursor inside a MFD also with keys or the joystick one would just need
to write to the according properties and to the canvas it looks just
like any other mouse event).
- Window Stacking:
New windows always appear on top of older windows. It would be nice
to have the possibility to change stacking order (either reorder
the windows or use z-buffer with different z-values)
The window manager could eg. listen on a special signal property on
each window (eg. /sim/gui/canvas/window[i]/raise) which moves the
according window to the top of the current window stack.
I'd prefer window reordering because it would make checking for a
window at a given position very ease, because we'd just have to
check for the first match in revers stacking order (from topmost to
lowest window).
Have either of you thought about implementing the menubar? Which in PUI is a
series of popup-windows, just wondering if the 'window manager' needs to be
aware of such windows in terms of z-ordering.
- (Canvas Element) Picking:
Forward mouse events to canvas elements (trigger onhover, onclick,
etc.)
The canvas could listen for creation of the signal properties and
then add the according region to a list of monitored regions. If
the cursor is in one of the regions the property is signaled.
Ah ok - can you explain more how you see this working? I'd imagined passing
a Nasal function as a callback into the element:
element.setHoverCallback( fun = { } )
element.setClickCallback
element.setWheelCallback
and so on...
I was thinking exactly the same. the setXxxCallback functions would just
add a listener to mouse/event, and upon change read all values into a
hash and call the registered function.
- Use images inside Canvas:
We need a new element type to also display images and other textures
(eg. also the texture of another canvas) inside a canvas. Not
everything can easily be represented using just vector graphics, so
images will also be needed.
Right, the 2D panels are just textures. I will also add a 'scale 9' (aka CSS
border image) element since my impression is this would be very useful in
styling GUI elements.
Sounds useful. Maybe we can do also an element which supports this for
vector images (eg. for buttons, inputboxes, etc.)
One thing I want to fix for 2D panels, the GUI and 3D picking is cursor
feedback. So if a 3D model or 2D 'knob' is clickable, we can show a
hand-cursor and a tooltip on hover. This would be a *huge* usability win for
people learning new cockpits, besides the GUI. Unfortunately OSG cursor
support is somewhat limited.
With osgGA handling mouse over events is now also possible. So for
canvas elements adding tooltips is very easy. For 3D picking we would
need to forward the mouse intersection to Nasal. This will also be
needed for interacting with canvases placed on 3D surfaces.
Personally I'd like an event class exposed to Nasal (I can do that part, lots
of experience with it now!), which is available in the callback functions I
suggested above: so in a hover / wheel / click callback, one has an 'event'
object with:
event.button (button that triggered the event)
event.type (press / release / click / double-click)
event.time (maybe...)
event.buttons (state of all the mouse buttons)
event.modifiers
event.x, event.y
event.globalX, event.globalY? (do we need these?)
And this can potentially have some helper functions to transform X/Y
coordinates or even find the lat/lon of the scene location...
Looks like a good idea (relative changes would also be useful eg. for
dragging). The question is only if we need to expose this class from C++
or if it is enough to build it in Nasal.

I was assuming I'd create a Nasal ghost for Canvas::Element, and another for
osgGA::Event, or a Canvas::Event if we need an explicit class. Then we need
some global Nasal C functions to map from a Canvas property node to the Nasal
ghost (i.e finding the underlying C++ canvas::Element).
What shall the ghost for the canvas::Element do? I think it would be
enough to have a set(event)handler(path, event_type/mask, cb) and
remove(event)handler function which work similar to the property
listener functions:
sethandler('/canvas/texture[2]/group[3]', 'click', func(event) {
print('click at ' ~ event.x ~ '|' ~ event.y);
});
or
sethandler('/canvas/texture[2]/group[3]', 'mouse', func(event) {
print('mouse event ' ~ event.type ~ ' at ' ~ event.x ~ '|' ~ event.y);
});
I'm not really sure if we need to differentiate between different mouse
events already at C++ level or if just passing every mouse event is
sufficient.
Finding the acording canvas::Element is really easy as the first part of
the path can directly be compared to the canvas base path (see
canvas_mgr.cxx and property_based_mgr.cxx) and access the required
canvas by it's index (only possible with canvases) and afterwards
recursively checking for element name and index.
Can Nasal ghosts also be used with an inheritance hierarchy? Eg. having
an event base class and mouse, keybord, etc. events. Events may have
something in common, but eg. for mouse and keyboard most of the data
will be different.
All of the above is only a few lines of code and I've been doing it for
FGPositioned recently - it's pretty easy. Once that's done we define the
'addXYZCVallback' methods in C++, and have them capture an naFunctionRef for
the callbacks - again I've already done this and it works nicely. When the
C++ element receives an event it can check its registered callback list, wrap
the event in a ghost and run whichever callbacks apply.
If you want me to prototype some code for this, I am happy to do so!
Would be great :)

Re: [Flightgear-devel] Switching from PUI to osgWidget
the osgWidget base class. In particular my goal is to be able to kill off fg_os.hxx in the near future, i.e to have all events being passed into the canvas as osgGA types, not the old GLUT interface of raw x/y floats. The current window manager registers itself to the main viewer and subscribes on osgGA events, so the canvas has no dependencies on the old system. What do you think about the current way of handling mouse events? It's also just passing x/y and some more values to the property tree, but we need to forward the values somehow. Also I had to create a new event class (which uses most of the osgGA types) because the coordinates of the mouse where passed in the range [-1,1] which would make handling a bit more complicated...

Re: [Flightgear-devel] Switching from PUI to osgWidget
2012/7/26 James Turner zakal...@mac.com: Okay, I wasn't clear from the Wiki page what the final idea was. As you say, so long as we're going through show-dialog it should be fine. My feeling is we still want a C++ hook around creating individual widgets, so we have the option the create custom widgets in C++, but it's not a difficult thing to change internally. You can always create widgets from C++ by adding canvas elements through the property tree, but I think a fully scripted GUI is the most flexible and powerfull approach. Do you have any usecase where you wan't to create a widget in C++? Hmm, I wonder if having a C++ base class for widgets in the canvas will simplify picking and mouse-over. To avoid such details to the basic canvas item. I'm currently thinking of adding a property to each element which allows enabling picking for this element. If the element is a group it receives picking events from all children otherwise only its own. We should also keep in mind that the Canvas won't be used only for the GUI but also eg. for MFDs which may have a touch interface where not necessarily widgets are used...

Re: [Flightgear-devel] Switching from PUI to osgWidget
2012/7/25 James Turner zakal...@mac.com: Thomas, I have the impression you've been working on this stuff for a while, could you please summarise how you see it developing so Stefan and I can see where we might help. I think it now slowly reaches a state where everything starts to stabilize. The API is really easy to use and most things should be already possible without any modification to the C++ code. Now we need to extend the API, create some helper functions/classes and have a look what is possible and what is still missing. I'm pretty concerned to keep the Nasal code sufficiently structured that we vary the widget implementation without updating the dialogs. In particular, I'm concerned that we don't end up with inline Nasal dialog XML which depends on the widget implementation internals, simply because that's convenient in Nasal. (for example, the current dialog XML files don't know anything about 'mouse-handling', they work exclusively in bindings, and that's a good separation of UI events from semantic behaviours) I have based the implementation on many ideas from different existing technologies and projects. The most important are the Javascript DOM API and some Javascript/SVG/drawing APIs (eg. jQuery SVG [1]). For mouse handling I like the idea of having event handlers (eg. click, drag, hover, etc.). So instead of just one property holding the events of the whole dialog/canvas I want to forward the event to the according element by using picking or maybe for a first step just bounding box checking with the current mouse position. It would still just set the three properties like before (button, x, y) but we could add an helper function which adds a listener to the button property and calls a function with all three parameters if the event was triggered. (I always want to keep the basic idea of only communicating via the property tree). I'd also like to see / understand how we manage XML / property-list file processing in a nice way, to support the various formats we want to create canvas elements from - GUI dialogs, 2D panels and HUDs. We could for example just add some more parseXXX functions (like parsesvg) which parse a dialog/hud/whathever file and create a canvas from it. So we would just have to modify eg. the show-dialog command to create a canvas and call the parser. So, yes, if you could explain your plan here, and where people could help, that would be useful. Missing things: - Documentation: Read, ask questions, extend. I haven't done too much documentation (apart from inline documentation) just due to the reason that the API is not completely stable yet. You could also try different use-cases and maybe find some examples where the API lacks some features. - Clipping: For different reasons we will need to be able to clip some elements to certain regions. It should work with specifying either a clipping rectangle or by using a path. OpenVG seems to have support for it, although I haven't looked into it too deep. We also need to ensure that it also works with text. - Geographic Mapping: It's very experimental, missing different projection modes (eg. vertical projection) and especially the Nasal API feels very hackish. - Picking: For mouse handling some kind of picking would be nice. As already mentioned, at least bounding box intersections will be needed. - Animations: I don't know if we should do animations just be using interpolator and settimer from Nasal or if we should implement some time-based animations directly in C++. At least we need some helper functions (eg. for blinking elements - cursor, fading, ...) - Improve PUI to allow eg. receiving mouse over events. - Improve the Nasal API: Add some helper functions for animating different glass cockpit displays (I have already some basic code, but it needs some generalization). - Implement some widgets in Nasal. - Check what is missing to implement the different hardcoded instruments. - Allow placing images inside the canvas. - Maybe support displaying shapefiles. - I also want to unify the canvas creation a bit, such that canvases can be moved seamless between the different placements (gui, model, hud, etc.). The normal model placement is great but the gui widget placement needs to be able to also use an already existing canvas. - Support copypaste: I'm working on the selection part, but have no clue yet on how to access the system clipboard. - Find more work I've currently forgotten about :) Please also have a look at the wiki [2]. There is already plenty of brainstorming outcome and also information about some current features.

My feeling was that osgText was going to handle multi-line text fairly badly, and this might be an issue. We don't have many multi-line text widgets, but they're some useful ones - e.g. the Nasal console. I have just experimented a bit with osgText and multi-line text. So far I didn't notice any problems. Regarding canvas, I think that that is definitively the way to go for stuff like the map widget, but to be honest I have my doubts whether it would be suitable for the entire gui. I must admit though, so far I've only read the documentation on the wiki, so I haven't played around with it yet. Right, canvas makes more sense for the map-widget and replacing the old OpenGL calls in the HUD is my feeling; to build something compatible with the current GUI using the canvas might be possible, but is a lot of work. But using the Canvas also for the GUI would give us the advantage of a unified rendering backend for any type of GUI/text rendering and also the ability to use the same widgets everywhere - eg. use them also inside aircrafts for CDU GUIs or other displays...

[Flightgear-devel] Canvas (2D drawing API) - Testing needed
Hi, I'm currently working on a 2D drawing API. The basic idea is to draw arbitrary 2D shapes and text to a texture and place this texture on some model in the scene (eg. display, HUD,...). This so called canvas should be controlled only by using the property tree. Currently it is possible to draw text, transform it, change style and all of this through the property tree. I have also added an experimental Nasal API which provides an object orientated wrapper around the property tree interface to the canvas. The code is already include into flightgear/next, but some fixes and the Nasal API are waiting to be merged into flightgear and fgdate respectively. I have already tested many scenarios but it would be great if you can try it out on your own and report bugs or provide some feedback :) Please see http://wiki.flightgear.org/Canvas_Properties for more details.

[Flightgear-devel] Replace texture with RTT
Hi,
I'm currently experimenting with a 2D Canvas and rendering everything to

FGODGauge::set_texture to replace a texture in the cockpit with the
texture from the fbo. This works very well unless I enable any effect
which causes the texture to be replaced by the original one.
I have just extended the ReplaceStaticTextureVisitor::apply(osg::Geode
node) method to also replace texture inside effects:
virtual void apply(osg::Geode node)
{
simgear::EffectGeode* eg =
dynamic_castsimgear::EffectGeode*(node);
if( eg )
{
osg::StateSet* ss = eg-getEffect()-getDefaultStateSet();
if( ss )
changeStateSetTexture(ss);
}
else
if( node.getStateSet() )
changeStateSetTexture(node.getStateSet());
int numDrawables = node.getNumDrawables();
for (int i = 0; i numDrawables; i++) {
osg::Drawable* drawable = node.getDrawable(i);
osg::StateSet* ss = drawable-getStateSet();
if (ss)
changeStateSetTexture(ss);
}
traverse(node);
}
Does anyone know how I can correctly replace a texture, such that it
also stays there if effects are enabled (eg. generic effect).
Thanks,
Tom

[Flightgear-devel] FG hangs on loading scenery when using many objects
Hey group, I've come across a problem with FG when many (static) objects are to be loaded on FG startup. Usually, on my (faily old) PC FG loads for about 20 seconds, then says loading scenery for about 6 seconds, and places me in the c172 ready for takeoff. During all this CPU load is at 100%. Now if I start FG with scenery that contains many ( 1000) objects, I get the following: - FG still loads for about 20 sec, then says loading scenery - about 3 seconds later, CPU load drops to ~20% and stays there - and FG never finishes startup --log-level=debug shows the main loop is running, I can use the menu, but I never end up in the c172, nor see anything else but the splash screen Starting at a nearby airport and flying into said scenery works. I can also teleport to this nearby airport while FG 'hangs', and then fly into said scenery flawlessly. I've created a test scenery [1] which uses TNCM terrain and 5000 instances of one object, furthermore, a script which lets me reduce the number of objects in the .stg. If I use 3100 objects, everything is fine. 3200 objects, and FG hangs. 100% repeatable, though I did not narrow down the threshold number further. However, the threshold number seems to depend on - the object(s) loaded - CPU load: If I have another process running (mplayer, for example) which consumes some CPU, FG now also hangs for the 3100 objects case (which would otherwise load fine if there was no other demanding process). It appears as if FG somewhat locks up if the initial scenery is not loaded within a certain wall clock time. Any ideas?

Why they chose a stop in Stillwater, I'm not sure. Maybe because of its history as an air depot in WWII and a place where some 470-something WWII warbirds were parted out for scrap after the war (google Searcy Field).

Also, do you have a bug tracker or other preferred means of reporting issues or feature requests? One feature that I have thought would be good for any fgfs launcher is a simple multi-player server ping to find (and automatically select?) the closest mpserver. If there is a way via the mp protocol to count the number of players already on each server, that information could also be used to help select the best server to connect to. Anyway, thanks for working on this application and, though I don't have a lot of time to spend on it, I would like to help in any way that I can. -Reagan Thomas -- EditLive Enterprise is the world's most technically advanced content authoring tool.

Re: [Flightgear-devel] Night textures: two files vs. textranslate
Heiko, Emilian, thanks for your answers! @Heiko: The wiki article correctly describes the textranslate method. What puzzled me was that it says the previous, two-file solution would no longer work. Well, apparently it does here... http://flightgear.org/forums/viewtopic.php?f=5t=11870#p123517 @Emilian: I wasn't aware of that lightmap effect, thanks for the heads-up! It would certainly suit better here.

[Flightgear-devel] Night textures: two files vs. textranslate
Dear all, I'm in the process of converting X-Plane scenery to FG. As far as I understood, X-Plane uses two separate texture files for day/night lighting. The FG wiki (http://wiki.flightgear.org/Howto:_Illuminate_faces#Changing_texture_if_illuminated) says This does not work with any version newer than v1.0! However, I just tried this with my GIT (compiled somewhen in Feb 2011), and it worked nicely. Is this way of night texturing deprecated/obsolete? Any significant downsides to it? I also tried the textranslate method, but when I put the day/night textures, say van.png and van_LIT.png each 256 x 256), into one file (512 x 256) and make up an .xml as described in the wiki, both day and night textures look distorted in FG. I assume the mapping specified in the .ac is no longer correct when I change the size of the texture file? I have no experience with UV mapping though. Any ideas?
