Re: [osg-users] GTK guru's please help!
On Wed, 2008-11-19 at 20:51 +, Robert Osfield wrote:
Hi Guys,
I'm now wrapping my first pass at browser support in the OSG by moving
the LLMozLib/LibXUL implementation in the osgbrowser example off into
a plugin. The work moving the code was pretty straight forward as
I've always had this change in mind, but now I've moved on to
debugging the code... which is where some GTK assistance would be of
great help.
GTK is required under Linux when using libXUL/xul-runner as gecko is
based on GTK under Linux, and even though we are using a embedded
browser for renderer where GTK doesn't have an influence, libXUL still
needs to be passed a GTK widget and the workaround using in
UBrowser/LLMozLib was to create a widget pass this to libXUL and then
never use if for actual application windowing. This is pretty hacky
but does work, or at least it did work when the code was in the
osgbrowser application. Exactly the same code, executed in exactly
the same sequence is hanging on the first call to gtk. The line of
code that my app is hanging at is:
gtk_disable_setlocale();
This is the first call to GTK in the whole app, there aren't even any
X11 calls made before this either - just in exactly the same way as
done before when inside osgbrowser. The only difference is that the
plugin that contains this GTK init code is dynamically loaded at
runtime.
So... does this ring any bells for GTK users? Is there some caveat
that GTK can't be dynamically loaded as a plugin?
The stack trace at the hang shows GTK stuck in a mutex lock. The
UBrowserManager::getNativeWindowHandle () code at the bottom of the
below trace is my method that calls gtk_disable_setlocale();
#0 0x2b83392f1af8 in __lll_mutex_lock_wait () from /lib/libpthread.so.0
#1 0x2b83392edaf5 in _L_mutex_lock_252 () from /lib/libpthread.so.0
#2 0x2b83392ed4e7 in pthread_mutex_lock () from /lib/libpthread.so.0
#3 0x2b8337a4f15b in ?? () from /lib64/ld-linux-x86-64.so.2
#4 0x2b8337a52864 in ?? () from /lib64/ld-linux-x86-64.so.2
#5 0x2b8337a58a52 in ?? () from /lib64/ld-linux-x86-64.so.2
#6 0x2ab3e7c8 in UBrowserManager::getNativeWindowHandle ()
from /home/robert/OpenSceneGraph/lib/osgPlugins-2.7.6/osgdb_gecko.so
The complete function where the hang occurs is provide below,
including my notify statements that isolate how far the thread gets,
the second notify statement - the AA is never executed.
void* UBrowserManager::getNativeWindowHandle()
{
if (_nativeWindowHandle) return _nativeWindowHandle;
osg::notify(osg::NOTICE)UBrowserManager::getNativeWindowHandle()
Astd::endl;
gtk_disable_setlocale();
osg::notify(osg::NOTICE)UBrowserManager::getNativeWindowHandle()
AAstd::endl;
gtk_init(NULL, NULL);
I've always been under the impression that gtk_init() has to be called
first before any fuction that begins with gtk_*, have you tried moving
it as the first call instead of disable_setlocale?
What if you call gtk_init() in the main code before doing anything
that forces the loading of the plugin?
osg::notify(osg::NOTICE)UBrowserManager::getNativeWindowHandle()
Bstd::endl;
GtkWidget *win = gtk_window_new(GTK_WINDOW_POPUP);
// Why a layout widget? A MozContainer would be ideal, but
// it involves exposing Mozilla headers to mozlib-using apps.
// A layout widget with a GtkWindow parent has the desired
// properties of being plain GTK, having a window, and being
// derived from a GtkContainer.
GtkWidget *rtnw = gtk_layout_new(NULL, NULL);
gtk_container_add(GTK_CONTAINER(win), rtnw);
osg::notify(osg::NOTICE)UBrowserManager::getNativeWindowHandle()
Cstd::endl;
gtk_widget_realize(rtnw);
GTK_WIDGET_UNSET_FLAGS(GTK_WIDGET(rtnw), GTK_NO_WINDOW);
osg::notify(osg::NOTICE)UBrowserManager::getNativeWindowHandle()
Dstd::endl;
_nativeWindowHandle = rtnw;
return _nativeWindowHandle;
}
Only other clues I can provide is that I'm calling GTK from a
background thread that the plugin starts for the purpose of doing the
browser rendering. All GTK calls are made from this single thread.
This code threaded approach worked perfectly when the code was inside
osgbrowser, the code itself identical - I just copied it into the
plugin.
I'm stumped so would love some greater wisdom as my GTK experience
goes about as far as this little osgbrowser folly :-)
Robert.

Re: [osg-users] OSG with CEGUI
I can't really comment much about CEGUI, but I do plan on releasing a VERY alpha version osgHUD here in the next few days if you're interested in trying it out. It doesn't have anywhere near the amount of pre-created widgets as CEGUI, but it is written using native OSG--and hopefully provides (or will one day provide :)) enough basic framework for people to create fully-featured OpenGL UI kits... At any rate, I'm sure CEGUI is a fine piece of software. :) As to how to get it working properly with OSG, I'm not sure...

[osg-users] osgHUD 0.1.0-alpha
A few months ago I made a post describing a piece of software I was
working on. Unfortunately, I've been very busy since then (Bioshock,
Halo 3, Orange Box, work...) and haven't had much time to work on it.
However, the last few weeks I've been spending a bit of my free time
working on it again, starting from scratch, and have come to a point
where I'm ready to at least put it out there and see what people
think.
Thus far osgHUD is very primitive, and doesn't support nearly the
feature set it eventually will. The basics are there though, and the
main point of my posting it here is to get opinions on the progression
of the software and get some ideas/advice for what I can change.
You can find the SVN 0.1.0 tag here:
svn co http://osghud.googlecode.com/svn/tags/0.1.0 osgHUD
...I wouldn't recommend using trunk, as it is often broken. I only test
and develop on Linux using GCC ICC, but nothing about the code is
Linux-centric. To build it, just do:
# cd build
# ccmake ..
3 small examples are provided: osghud{box, window, label}, which
demonstrate some of the basic functionality of the current state of
osgHUD. osghudwindow is heavily commented, and a great place to start
checking things out.
The following is a short list of what will be included in 0.2.0, which I
will hopefully be done with over the weekend:
- Table-like layouts (think HTML tables)
- The ability to hide/show Widgets.
- A DecoratedWindow subclass of osgHUD::Window, which will
provide the standard titlebar, open/close/minimize, resize,
etc. of a standard window.
Of course, there is MUCH more to do before osgHUD is ready for serious
submission into OSG, but this should give people a good idea of where I
plan on taking it in the next few days or so...
Please feel free to post feedback here or send me e-mail directly. Also
note that some of the current code is less concrete and more an
experiment in using C++ functionally (i.e., std::accumulate,
std::for_each, etc.) I can remove these instances if people find them
distasteful.
Also, there are two other projects I host on Google, osgCairo and
osgEgypt, which some people might find interesting (and which I've
talked about on these lists a few months back).

Re: [osg-users] osgHUD 0.1.0-alpha
I forgot to mention that--as you might expect--the proper functionality
of a HUD relies on the camera's orthographic projections matrix being
set correctly. All of the examples use 1280x1024, and you can use a
command like the following to get the desired result:
# OSG_WINDOW=0 0 1280 1024 ./examples/osghudbox/osghudbox
On Windows, er, um, you might need to recompile the examples w/ the
proper resolution. :)

Re: [osg-users] how to manage different model types
Probably the easiest (and perhaps only sensible) way is to use osgconv to adjust the model transformations before loading them into your app, and not to address the issue at all with any kind of code. Its really up to the asset to encode this information consistently within itself... osgconv -h ...will tell you almost everything you ever wanted to know. :) On Thu, 2007-12-06 at 17:13 +0100, Stephane DUGUET wrote: Hi all, I have a general question about model orientation. If I get several models from several sources (flt, 3ds etc…). Their original orientation may be different depending on how they have been built.

If I place these two models at origin one is pointing head to north and the second is pointing head to east. Meaning that the views, position and transformations for plane and copter have to be different. Is it possible to make it generic (at least linked to a terrain)?

Re: [osg-users] Looking towards 2.4, and what might go into it.

I doubt I'll get all the way through before Monday, but on Monday I'll tag the first dev release since 2.2 stable was made. This dev release will be 2.3.0 and be the first concrete step towards the final 2.4. This leads me on to asking the question - what features should we aim to integrate with 2.4? My own short list for contenders for integration are: osgOQ - Occlusion Querry support osgCal - Cal3D integration I noticed there was a lot of Cal3D discussion going on here so I'd figure I'd chime in and say a few things. I have write access to Cal3D SVN I obtained a year or so ago when Palle Raabjerg and myself rewrote the Cal3D Blender exporter, which we built by starting from the version in the Soya project; I've also fixed a few small bugs here and there in Cal3D proper. I'm pretty familiar with Cal3D in general, and with the various Cal3D OSG plugins that exist. As a matter of fact, I'm the one who made the Cal3D videos on the website, and I used OSG to do it. :) http://home.gna.org/cal3d/ For a bit of info (and some personal opinion): Firstly, there is the generally-referred-to osgCal (officially called osgCal2), which was originally made by Ruben Lopez and has had many additional edits since then. There is also a GPL version that is incredibly more sophisticated which was created by the people at Underware, but the license wouldn't not allow for wholesale inclusion into OSG. Vladimir Shabanov recently made some changes to osgCal2, and I believe he and Ruben coordinated so that his changes were committed upstream. However, as I mentioned back then and I believe Jan Ciger has alluded to earlier in this thread: the code will need a lot of love before it's ready for serious inclusion. For example, the last time I checked, the shaders were somehow parsed by sed before actually being written into a valid shader file, and there's simply no way I can see anyone in the Windows or Mac world willing to accept such a restriction. One thing that should be kept in mind when using Cal3D is that in it's current state, Cal3D isn't a skeletal system alone--it's a skeletal animation system+mesh format, and one cannot be divorced from the other. Furthermore, there is a lot of data reproduction in Cal3D that already exists in OSG, and no way to easily (or cleanly) make changes therein. In the opinion of someone who is familiar with Cal3D, I'd say that we wait a bit on inclusion of this until someone has the time to cleanup the current plugin. Hardware skinning is a pretty common performance boost these days, and whatever solution arises for OSG, I'd personally look at support for this feature as the make-or-break aspect. We also need exporters, and while I wrote a significant portion of the Cal3D Blender exporter currently in SVN, I did it at a time where my knowledge of both Cal3D, Blender, and graphics/3D development in general was very poor, and thus cannot attest for it's reliability or cleanliness. :) As far as ReplicantBody is concerned I'm unsure--I've never looked at it. To be completely honest, character animation is such a huge issue unto itself that it probably deserves a lot of discussion and review before any steps are taken--but that's just my opinoin. Every time I'm forced to put any thought into the issue, I just get sleepy. What we __really__ need is an osgSkeleton NodeKit, which can then be exercised/demonstrated in the Collada importer, but would be usable alone as well in true OSG style: osgSkeleton::Skeleton* skel = new osgSkeleton::Skeleton(); osgSkeleton::Bone* root = new osgSkeleton::Bone(); osgSkeleton::Bone* child = new osgSkeleton::Bone(); root-addChildBone(child); skel-setRootBone(root); I bet once a basic, simple system was released, people would go to town making the necessary changes to bring it up to speed with other kits. It wouldn't have to be perfect, but as long as it was adaptable and done in true OSG fashion, people could subcass things in osgSkeleton for their own uses or to inject their desired interpolation algorithms (which is a big area of interest for animations buffs)... P. S. When I finish a release-candidate version of osgHUD (or whatever you want to change the name to), I'll be peddling that for inclusion as well. :) I've made a number of changes in the last few days if anyone is keeping up with SVN, and almost done with a decent implementation of a table layout, very similar to how HTML tables are done... however, no one posted any complaints to my first thread, so I'm just going to keep proceeding as normal, though I did remove the silly functional code that no one could have possibly understood but myself... it's a shame how difficult it is to do use something as [conceptually] easy as std::for_each()--it's a nightmare, when you can almost always

Hi all,
I'm writing a little application which renders images to texture and
passes them out to a Matlab program. So far it all works fine, but I
was wondering if there is any way I can get rid of the window that

as the only camera in the scene graph is set up for RTT, so its just a
bit untidy. I'm running windows XP if that makes any difference.

Surprisingly, something like this is more difficult to do on each OS
(and the case of Linux, WindowManager) than you might imagine! I'm
guessing OSG doesn't currently support this with it's 3 main
GraphicsWindow{Carbon,X11,Win32} classes, but I'm not 100% sure. The
latest SVN version of SDL has a function called SDL_HideWindow, which
purports to do what you want as well...
As a sort-of workaround you could add a small osgText::Text object that
shows some spinning Please Wait... text, along with setting the
OSG_WINDOW variable to your desired orthographic size. This way, it'll
look like you meant to open that window. Or you could put some fancy
stats in there and whatnot... :)
Not an acceptable solution in every case, but maybe a humorous one!

I ask in terms how much effort would it be required to reimplement the unique parts not found in the core OSG? It's hard to say--there's a lot of code in Cal3D supporting the mesh format, XML loading, matrices, vectors, quaternions, etc. If I had to estimate, I'd guess OSG already contains 20-25% of what Cal3D has to implement itself to be graphics library/system agnostic, and another 20-25% or so is code relating to it's mesh format. So, you'd probably have to re-implement half of it... :( In the opinion of someone who is familiar with Cal3D, I'd say that we wait a bit on inclusion of this until someone has the time to cleanup the current plugin.

I thought there was already hardware skinning support in place. So which versions which hardware skinning? Not in Cal3D itself. The software doesn't make any attempt to bind itself to any graphics API, so things like hardware skinning are left up to the user (though they do include examples using the old shader/assembly code or whatever it's called).

If you can get osgHUD ready for integration then I'm very open to reviewing it with a view to inclusion in 2.4/2.6. We do need to save people from the trials and tribulations of going with something like CEGUI. 2.6 is my goal... W.r.t awkwardness of some program concepts, C++ is the culprit here. My own feeling is that scripting languages shine for high level GUI work. One could use a scripting language for both the control and the layout setup.

[osg-users] AnimTK
With all the recent discussion over Cal3D I decided to take a few minutes and look over some of the affiliated stuff at Gna.org and I found a project called AnimTK. The memberlist includes Loic Dachary (who also posts here from time to time and is/was pretty much the lead Cal3D guy) and Cedric Pinson (who also posts here), so I'm curious what this is and what it does, as it seemed to both use and be heavily influenced by OSG (naturally). ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] osgHUD 0.1.1 ALPHA
Just wanted to give another heads up on the state of development and perhaps solicit some more feedback (which has been very small so far, seeing as there isn't much code yet--only about 2100 lines). There is an SVN tag of 0.1.1, and a new tarball in the downloads section. http://code.google.com/p/osghud/downloads/list All the normal stuff applies (seriously alpha, blah, blah), but I'm interested in getting opinions and perhaps having people catch any bad design decisions I'm making before it's too late. The biggest differences in this from the version from last week is a great deal of code simplification and the addition of a small skeleton for a table-like layout (osgHUD::Table). In the next 0.1.2 testing release I'm aiming to add support for basic texturing. However, it's an issue I need to approach carefully, because it can really start to go wrong here. :) Remember to set OSG_WINDOW before running the examples. # OSG_WINDOW=0 0 1280 1024 osghudtable ...or else you'll need to modify the examples to use your fullscreen resolution in the 2D ortho camera for picking, moving, etc. to work as you might expect.

First of all, thanks a ton for the feedback! :) Keep reading below... On Fri, 2007-12-14 at 10:32 +, David Spilling wrote: Jeremy, I am very keen on experimenting with your HUD. However, as a Windows/VisC++ 7.1 user, I have a lot of difficulty with the code. I'm not a cross-platform expert, so I have difficulty in knowing how to simultaneously specify a windows and linux acceptable build. I can submit my stuff to you, but don't know how useful it will be. I did the following: Minor points: 1) Constructions like not and and or aren't recognised by MS .NET 7.1 out of the box; I had to replace them all with !, etc This is pretty frustrating, because I'm about 99% sure these are acceptable C++ keywords. They look about a thousand times better in the code, but if Windows won't support them I'll drop their usage. I build with both GCC and ICC (Intel's compiler), all warnings turned on, and neither of them have ever complained about this... 2) uint isn't recognised either; I replaced it with unsigned int Whoops, I knew this but it looks like I left out 2 instances. :( 3) std::sort wants #include algorithm Fixed. 4) I need to link to osgText, osgDB and osgGA to build; these aren't in any of the project files Fixed. 5) osgHUD::UIObjectParentosgHUD::Widget::getByName is reported as being recursive, similar with osgHUD::Widget::getWindowManager Hmm, weird. I've introduced an alternative implementation. It's necessary to have const and non const version of these functions though, and I really don't want to have the exact same code copy/pasted. Major points: I added the usual windows exports header file, something like this: #ifndef WIN32_LEAN_AND_MEAN #define WIN32_LEAN_AND_MEAN #endif #include windows.h #ifdef osgHUD_EXPORTS #define HUD_API __declspec(dllexport) #else #define HUD_API __declspec(dllimport) #endif and then declare every DLL exported class, and things like createOrthoCamera(), with HUD_API. This all then works OK, and all the exes run just fine. Fixed (but using OSG_EXPORT instead). The WIN32_LEAN_AND_MEAN thing may appear somewhere else in OSG, I'm not sure... I haven't managed to review the code yet. We have an in-house HUD system which I would like to lever on to yours for future use; this may throw up some design issues when I do it (although it won't be for a while)... Hope that helps, Yes, very much. :) Can you try the new version I've put up with your changes (0.1.2) and let me know if it compiles on Windows okay without you having to modify too much?

It's only in the very alpha stages, but if you're already using your own homebrew solution, you may be able to adapt osgHUD and contribute the changes back to me. :) http://osghud.googlecode.com I'd really recommend using SVN for now if you want to experiment, as the tarballs quickly fall behind in these early stages.

Re: [osg-users] osgHUD compilation on Windows

Woot! :) From SVN updated today, here are the changed files to get it to compile correctly on Windows. First of all, some changes were needed to the CMakeLists.txt. - Need to link to the OpenThreads library. - Need to link to opengl32.lib or else the OpenGL symbols are not found. - Need a define of OSG_LIBRARY so that the OSG_EXPORT stuff works. This needs to be defined *only* for the lib (osgHUD), not the examples, which is why I put it after the ADD_SUBDIRECTORY commands. - Also, I added a second INSTALL line which will copy the DLL into the bin directory, only for Windows. - I decided to group all the Win32 stuff together at the end of the file, since the define needs to be at the end, and for the rest it doesn't matter where it is in the file. In the includes, I only had to remove OSG_EXPORT from one class. It seems it causes problems for template classes. I don't know the details, only that there was a linker error with OSG_EXPORT and removing it fixed it. I also checked the OSG for this, for example TemplateArray, and there's no OSG_EXPORT there either, so I guess it's OK. Perhaps someone else can fill us in on the details. In src, I just fixed a couple warnings (using an int as a bool, and using multiple '==' comparisons stringed together). You could choose not to merge those, but I always prefer to fix warnings when possible, even when it's one compiler's misguided warnings. Less visual noise in compiles that way. Is there any way you could send me the output of svn diff so I can see what was necessary? And fear not, I don't see this as my project, so everything that fixes something will be merged. :) My only hope is that with enough eyeballs looking at it, we'll be able to get it in OSG proper before May. Now, these changes get it to compile and link with 0 errors and 0 warnings for me. As a general comment, it might be nice to adopt the OSG convention of adding 'd' to libs, DLLs and executables when compiled in debug mode. Though this requires a bit more CMake skills than I think I have, I'll try to submit something for that soon. The next step is actually running it... First of all, is there somewhere I can download the images you use for your examples? And second of all, I'm getting an std::bad_alloc when I run anything other than osghudversion, so I'll try to dig into that a bit more tomorrow. Hmmm, I've got a few e-mails from people using Windows with success, but I didn't get too many details. If you can figure it out let me know, and I'll change it right away. BTW: SVN changes 3 or 4 times a day lately. :) So, you might get a seriously wonky checkout if you're watching SVN, but I guess that's how things go. For example, if you checkout SVN now you're almost certain to be amazingly confused at my attempts to introduce clipping for WindowInWidget so we can have a proper scrollable window. BTW, osghudversion prints OpenSceneGraph HUD Library The code for this was taken from the pertinent parts of osgversion, but perhaps I took some strange liberties. The source is only about 4 lines of code, so it would probably be easy to find out. :) On my mahcine it prints: OpenSceneGraph HUD Library 0.1.4 (pre-alpha) is that normal? Anyways, from your videos and the discussion here this really seems like osgHUD is on the path to becoming a really useful nodekit. I hope I can help in some small way. Good work.

This seems to be caused by the stringstream not holding on to the result of its str() method.

I solved it by making a static std::string (instead of a static std::stringstream) and returning that. I also added code so the version string is generated only once, like in OSG, but if you had good reasons to not do that, it's not significant anyways (for a function that will likely only be called once in the life of a program). It now prints the same thing for me as it does for you. Diff attached. Still trying to figure out what's happening for the other problem. BTW, what about the images? I asked if it was possible for you to make them available (as an osgHUD-Data package or a directory in your SVN or whatever)... Once I get serious textured examples I'll certainly put them in SVN.

This is all fine and well, and works exactly as advertised. However, with regards to quality, there is no guarantee (at least that I can see) that osgText won't set the position internally of the text to values that do not map 1:1 to pixels on the screen--that is to say, the position isn't necessarily pixel aligned. I looked at the code for osgText::computePositions() a bit, but figured I'd ask here first in case I'm missing something obvious. My question then is: is there a way to coerce osgText to use CENTER_CENTER alignment but enforce that the text itself is never positioned (at least as far as the X and Y planes are concerned) with a value that isn't pixel aligned? Attached are two screenshots of the osghudmenu example I'm working on (which is in SVN if anyone would like to see it!) at the moment. The first screenshot uses CENTER_CENTER and the second uses LEFT_BOTTOM. Of course, when I use LEFT_BOTTOM I have to position the text manually myself (which isn't hard, but certainly creates more code). In both cases I enforce that the X and Y values to pass to -setPosition() are floor()'d, but that doesn't mean that osgText itself won't add 0.5f or so to the position, especially in CENTER_CENTER mode. To the discerning eye, you'll see a MAJOR difference... Hope I'm making sense. :) P. S.

On Jan 17, 2008 3:44 PM, Jeremy Moles [EMAIL PROTECTED] wrote: (This is a separate issue from my blending question which I posted earlier this week) In osgHUD, it is very convenient for me for various reasons to set the osgText alignment mode to: osgText::Text::CENTER_CENTER ...which allows me to put a bit of text in the center of a quad and delegate the responsibility of positioning to my osgHUD::Widget API. This is all fine and well, and works exactly as advertised. However, with regards to quality, there is no guarantee (at least that I can see) that osgText won't set the position internally of the text to values that do not map 1:1 to pixels on the screen--that is to say, the position isn't necessarily pixel aligned. I looked at the code for osgText::computePositions() a bit, but figured I'd ask here first in case I'm missing something obvious. My question then is: is there a way to coerce osgText to use CENTER_CENTER alignment but enforce that the text itself is never positioned (at least as far as the X and Y planes are concerned) with a value that isn't pixel aligned? Attached are two screenshots of the osghudmenu example I'm working on (which is in SVN if anyone would like to see it!) at the moment. The first screenshot uses CENTER_CENTER and the second uses LEFT_BOTTOM. Of course, when I use LEFT_BOTTOM I have to position the text manually myself (which isn't hard, but certainly creates more code). In both cases I enforce that the X and Y values to pass to -setPosition() are floor()'d, but that doesn't mean that osgText itself won't add 0.5f or so to the position, especially in CENTER_CENTER mode. To the discerning eye, you'll see a MAJOR difference... Hope I'm making sense. :) P. S.

[osg-users] osgHUD 0.1.4 (testing)
Well, it's Friday again. Lots of changes since 0.1.3 last Friday, and here's the CHANGELOG: http://osghud.googlecode.com/svn/tags/0.1.4/CHANGELOG You can find the Project Page here (with some videos, downloads, and the monospace.ttf font I use in a few examples): http://osghud.googlecode.com I'd say I'm pretty much on track for getting this ready for real submission in the next month or three. The most interesting thing in this testing release is the osghudmenu example, which really demonstrates how easy it can be to set that kind of thing up... Lots of feedback this last week, and I really appreciate it!

osgGA::GUIEventAdapter::{getX, getY} is what I believe you want here,
but you'll need to know how to tie it all in together with your app,
which is a somewhat non-trivial thing (imo).
Of course, I'd encourage you to just use osgHUD--since it never hurts to
have more eyeballs looking at my code--but it may not be ready for your
use yet. :) However, nothing about what you've described here wouldn't
fit into osgHUD currently, though you'd need to inhert from
osgHUD::Window or osgHUD::Widget somehow. I'd be willing to help with
this if your code is public...
Also, osgHUD handles the picking exclusivity issues by requiring the
user provide a unique NodeMask when creating an osgHUD::WindowManager
object. I asked a few months back and was told this was the best way, so
I'd say the same would apply here as well.
(If you want to see how osgHUD does all this, check out SVN and look at
the osgHUD/ViewerEventHandlers file)

[osg-users] Hey Guys (osgWidget)
Jeremy here. I haven't posted or even received posts in about 10 months, so I've been out of touch. For those of you who don't know, I was (at one point) a moderately active participant in the OSG development/submission process. About a year ago I mentioned that I was diagnosed with Leukemia (which sucks because it's not something you ever expect at 28) and that I wouldn't have much time for coding. For the most part, that was--and remains--true, and as my condition has gotten worse my ability to function from day to day has definitely diminished. HOWEVER... I will be undergoing a bone marrow transplant here in the next 3 weeks, which will require I basically go into seclusion for 6 months to a year. I'll have LOTS and LOTS of time just sitting around, and I can't think of anything more I'd rather do while recovering than keep my mind busy getting back into hacking. :) I know that osgWidget has been around for a while now, but I'm not entirely sure people are actually using it yet. I'd like to try and come back and start hacking at this again, so I'm what I'm looking for are any comments people might have or complaints that may have surfaced while I was away. I have lots of good ideas, but I will basically be rewriting and SUBSTANTIALLY simplifying osgWidget to be a bare minimum and flexible NodeKit for doing the basic UI stuff (supporting 3D). Then, I'll add another layer on top (which will not be in C++, but instead in Lua) that will do most of what osgWidget currently does, since no one really wants to write UI code in C++ anymore. It's really, really dated and Lua is so small, sandboxed, and efficient there's truly no excuse not to use it. :) Anyway, I'm glad to have some of my motivation back. :) With the transplant happening soon and a fairly decent chance of it being successful, there is much to be optimistic about! ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Yes, some of us are using it. There are occasional questions on the list/forum, and I know I (for one) have submitted a few fixes for small bugs. I'd like to try and come back and start hacking at this again, so I'm what I'm looking for are any comments people might have or complaints that may have surfaced while I was away. Well, I have a few comments, and I'll probably have a few more later if I can get some more work into one of my pet projects that uses it. :-) For now, the major comment I have is: why oh why are the argument names omitted from the method declarations in the headers? If all you have to work with is the headers, figuring out what you should pass as arguments to a function like bool setImage (osg::Image *, bool=false, bool=false) can be hard. What are those two bools? Plus, they appear that way in the doxygen documentation too... See http://www.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01066.html I know it'll be a painful task to go and put the argument names back, but I think it has to be done... Other than that, it works well. If I remember well, I found the interface for creating a window from a theme a bit weird, but I don't remember exactly what I found weird, so I'll have to get back to you on that.

It's really, really dated and Lua is so small, sandboxed, and efficient there's truly no excuse not to use it. :) I would recommend, instead of removing the C++ code, why not just wrap it (basically exposing it to Lua) instead? Then you have the best of both worlds. People who want to do GUI in C++ (and there are some cases where it's desirable) can still do so. One of the hardest things when designing an API is that you need to keep in mind that people will want to use it in different ways. So even if in your projects you would much rather use Lua exclusively for your GUI code, other people will want to use it from C++ since they're used to using OSG that way, and your API needs to cater to both. I totally understand where you're coming from here--and indeed, there would have to be SOME low-level interface in C++ to build off of--but the bottom line is, you simply can't (or rather, I can't) build sophisticated, intelligent, and easy-to-use containers and GUI logic in C++ without it becoming unimaginably huge and unwieldy. :( I'll definitely keep what you said in mind though. Perhaps prototyping it in Lua first will make it a lot easier to go back in C++ and do it right... Note that I've diplomatically avoided saying what language I'd prefer to code my own GUIs in. Honestly, if I can build the Lua support easily on all platforms, I don't really care, but others will feel differently. Anyway, I'm glad to have some of my motivation back. :) With the transplant happening soon and a fairly decent chance of it being successful, there is much to be optimistic about! Excellent!

But, have you some documentation regarding its design and or future plans? So i don't spend hours thinking something you have already thought about! :) The first question i could ask is (read beyond the obvious): What is the very concrete objective of osgWidget? I'm not fooling here. I mean, its objective is to be a thin layer of abstraction to allows some basic ui programmability with osg or it is to be a complete ui framework for user interfaces on OSG? The first version I intended to be a full-blown UI NodeKit; far too ambitious. :) The second version will be a sensible, strong lightweight wrapper around the basics so that I can make something else to actually handle the complex bits of code (windowing, advanced grouping, etc), For example, a widget right now is hard-coded as 2D quad; this is pretty terrible design, but makes it easy to handle sizing issues. In the new version, widgets are just an abstract interface, and the library uses the bounding box to position them instead. Of course, this means that each widget must override a virtual resize method, but it allows for widgets of arbitrary geometric size and dimension. Are you still open to suggestions? PD: Your optimism is commandable! Good for you. I wish you the best! Keep going!

I have another question : to get events from our images, we've implemented from the osg::Image base class the update method. But what's the better way to call this update method ? Currently our quick and dirty method is to put a custom update callback to the geode or the geometry using the image which call explicitly the update. Is there any other way to have this update method called ? I'd be very interested in your opinion on this as well, Robert. I often find myself wishing that Image objects had an update() method as well, but I don't know if I'm misusing OSG or it makes the most sense for you to put logic in the parent Geode instead, like Sergey is doing.

There is a limit to the type of events you could get out too - as osg::Image doesn't know anything about the potential sublcasses from osg::Image. The InteractiveImageHandler is also in a similar position - it knows nothing about the osg::Image subclasses - just enough about osg::Image to pass events into it. To get events for the browser subclass from osg::Image one will need to know about that specific subclass i..e osgWidget::BrowserImage. This as yet isn't geared up for passing any events back or providing a callback mechanism for it, but this is for sure the place to put them. This way you could do a dynamic cast to BrowserImage and then add the extra handling your need. To do this we'll need to extend BrowserImage but this would be perfectly in keeping, BrowserImage itself is still in it's infancy, a first pass at what will be required for more fully featured browsing.

an
InteractiveImage base class for sharing features between
browsers and
other interactive images ?
I have another question : to get events from our images,
we've
implemented from the osg::Image base class the update
method. But
what's the better way to call this update method ? Currently
our
quick and dirty method is to put a custom update callback
to the
geode or the geometry using the image which call explicitly
the
update. Is there any other way to have this update method
called ?
I'd be very interested in your opinion on this as well,
Robert. I often
find myself wishing that Image objects had an update() method
as well,
but I don't know if I'm misusing OSG or it makes the most
sense for you
to put logic in the parent Geode instead, like Sergey is
doing.
The update method already exists (Image file line 327) :
virtual void update(NodeVisitor* /*nv*/) {}
But I think there is no visitors to call it (but I've probably missed
something too).
It's called by ImageSequence, actually, and does kind of the same thing
you and I are talking about, I think. :)

Now I just need some time for the new immune system to get strong and I'll be better than ever. :) Interesting thoughts on osgWidget, not one I was expecting from you, but I can see the logic behind it. osgQt does require Qt which isn't a small dependency so for a lightweight users interface osgWidget still has value. Before we could fully replace osgWidget with osgQt I definitely think it still has value; it just doesn't fill (what I believe) is it's niche. (more below) we'd need to address performance and threading issues that Qt introduces. When you say osgWidget should have been far small and more generic could you explain what you have in mind for a what osgWidget should have been? Sure. This is something I touched on briefly earlier this year as I was recovering but still frequently in the hospital, so couldn't produce much code. What osgWidget tries to be right now is a lightweight 2D interface library. Widgets are always quads, Windows are always Geodes, etc. What osgWidget should be is an even lighter wrapper around any generic Drawable. It should feed input events to these Drawables in an OSG-like way (perhaps by accumulating input data from the mouse/keyboard and stuffing it into a NodeVisitor). It should provide some very basic positioning rules for Widgets using their bounding boxes, not their dimensions in 2D space. Once that is done, I can take the old osgWidget and turn it into simply a 2D implementation of the real, more flexible new osgWidget. Quads would be a 2D, 4-vertex specialization of Widgets... so forth and so on. I'll be simplifying things immensely by providing just the hooks, and by NOT trying to cover every possible use someone might have. First of all, people will reach for things like QT instinctively if they need a FULL BLOW 2D interface in their app. Secondly, there are so many modern UI classes that people expect in any reasonable UI toolkit that providing even one opens the door to the question: hey, where are the rest? :) Robert.

Because of the language issues here, I'm afraid I don't fully understand
the question. However, osgWidget::Label uses an osgText::Text object
internally, so if it isn't supporting your language or encoding, perhaps
osgWidget isn't passing the string along encoded--though I do recall
testing that successfully.

[osg-users] [ANN] osgPango / osgCairo
Hello everyone! I have recently received funding from what must--for various reasons--remain an anonymous source, to further develop and refine osgPango. I've made some updates to the site with new screenshots and small descriptions, and I wanted to try and solicit some more feedback since it's been a while since I've mentioned them here: http://osgpango.googlecode.com A lot has changed with osgPango (far more mature and flexible API, no more fixed-function support, up to 8 combinable textures per font, multi-pass rendering) and I'd be interested to see what people think. In the very near future I will be providing the equivalent of the famous 3rd Party archive for osgPango for Windows. In Linux, it is quite trivial to compile both osgCairo and osgPango. In Windows, until I can create the necessary dependency libs, it's best to use the GTK Win32 Developers Bundle: http://www.gtk.org/download-windows.html In fact, my current client is using osgPango exclusively in Windows, so don't be too intimidated by the mention of GTK or anything like that! The current Text object (a derived class from osg::MatrixTransform) isn't a drop-in replacement for osgText::Text, but learning how to use it properly isn't hard. Plus, if you can position a MatrixTransform in your scene, you can position osgPango::Text geometry in your scene. :) Or you can create your own Text class and manipulate the Geometry however you want... I've also made some pretty significant changes to osgCairo that I'd like Robert to take a look at. :) A while back he had some interest in Cairo and didn't really like the idea of creating and maintaining our own C++ wrappers. Well, I've come around to that same manner of thinking, so osgCairo is really little more than a stripped down wrapper over osg::Image, a fancy ReadFile implementation, and a few commonly-used utility functions. It's a tad more sophisticated than what is already in OSG, but not by much. Perhaps we can revisit this interest that once was... ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

This button should open up, right below it, a dropdown menu, which is another box. The issue I'm having is that if I use getOrigin() or getPosition() for the button, I get a value of 0,0 which is where it is placed relative to the origin of the window it is in. This causes an issue because the window that drops down below it needs the actual position of the button relative to the entire screen. Is there some way I can get this absolute position of the button origin? Or is there some other way I can get around this issue so I can get the dropdown window to actually be below my button? You probably want to use the Window's ::getOrigin plus the Widget's ::getOrigin, plus any additional spacing you want. But from what you're said so far, everything is behaving as it should. Origin only differs from Position in that the Position returns the Z coordinate as well...

Basically, an example you can run: ./test --alignment LEFT_TOP --axisAlignment XZ_PLANE ...to quickly test the transformation code.

[osg-users] Jabber and/or OpenSceneGraph IRC
Hey, I just wanted to remind all of you lovely individuals that we have an IRC channel on Freenode. I know a lot of professional coders simply don't have the time or inclination for this kind of thing, but nothing would make me happier than to have real-time access to other people who use OSG day-in-and-day-out... Think of the things we could learn! :) What if we started our own Jabber network? I just got done doing a large XMPP project here at work and am now intimately familiar with the protocol/admin/etc. of Jabber networks... Would this be a resource people could be interested in? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Basic Lighting Shaders
I'm looking to collect some sample code from OSG users (if this code is shareable) for some basic lighting examples done purely in GLSL. If anyone is willing to share this (I can certainly adapt it, so there's no need to modify it), I'd be grateful. What I'm looking for mainly is how lighting code from source like the Orange Book are different/adapted to OSG. I've begun to compile OSG without support for the FFP, and I'm trying to work up a basic default set of shaders to emulate the FFP functionality. I'm very close, but I'm having trouble figuring out how exactly to caclulate the eye coordinate in my vertex shader when using osgViewer. Right now I'm using: eyePos = vec3(osg_ModelViewMatrix * gl_Vertex); ...but this starts to fall out of whack as I use the standard TracballManipulator. It works, of course, when in the home() position (and with a new ViewMatrix for the default camera with Y-up).

Re: [osg-users] improperly culled osgText

Turning off small feature culling does indeed fix my problem, but it's not ideal. It's not ideal at all, I'd call it hack ;-) I guess another hack would be to switch off culling off for the first frame and then re-enable. I'm not sure I understand all the details of what you're saying, but let me take a crack at it. With the current code you can a) turn off small feature culling, which will get you a bounding box of size 0 on the first frame and a reconstructed bounding box of the proper size on later frames, or b) leave small feature culling on, which causes your text to never be displayed. If there must be an incorrect bounding box on the first frame, maybe it should be just large enough to escape being culled as a small feature. Then small feature culling could be left on without any trouble. Of course, if there is any way to build a bounding box of roughly the right shape and size with information about the text to be drawn, that would probably be better. It sounds to me like things happen in the wrong order in OSG to make this practical or even possible. You are reading things correctly, as things stand the view dependent settings in osgText cause problems with sizing and computing bounding volumes for the first frame. Having a view dependent text in two different views will also cause similar issues with the bounding volume. I don't think there is any easy solutions without rejigging a number of design elements. For instance if I was write osgText::Text now I wouldn't put any of the view dependent support into it. Instead this should be provied by osg::AutoTransform, osg::Billboad or similar node level support. This will solve part of the problems, but there still is the issue with view dependent subgraphs and their bounding volumes which would need some resolution at the node level, unfortunately I don't know just what right now. TextNode will make this much easier, I think. Coming Soon (tm)!
