Re: [osg-users] multiple windows question

[Wang Rui]

Hi Alex,

The composite viewer can have multiple views of different scene graph on
different windows. Setup the Traits of each separated window and set it to
each view's camera, and setup your scenes with the View::setSceneData()
method.

[osg-users] multiple windows question

[Pecoraro, Alexander N]

What is the best way to have multiple windows with different views of the same 
scene graph? I took a look at the composite viewer example, but it has 
different views of the same scene graph with a single window. So not quite what 
I want.

Thanks.

Hi Russell,

Have you tried:

  viewer->done(true);

?

Re: [osg-users] Multiple Windows

[Russell Morris]

Yeah I did try that and it didn't work either. However, for some strange reason 
if I call the closing routine once when the window is created, and then again 
when I want it closed it works fine. Weird, I'm still trying to wrap my brain 
around what is going on. Thanks for the response! Have a good one!

Hi Morris,

Did you try to close only viewer;

   rViewer->getEventQueue()->keyPress(osgGA::GUIEventAdapter::KEY_Escape);
   rViewer->getEventQueue()->keyRelease(osgGA::GUIEventAdapter::KEY_Escape);

Regards.

[osg-users] Multiple Windows

[Russell Morris]

Hey all,
I've been searching the forums this afternoon and can't seem to find the answer 
to my question. I have a viewer setup with the following:

rViewer = new osgViewer::Viewer();

wm = new osgWidget::WindowManager(rViewer, width, height, 
MASK_2D, osgWidget::WindowManager::PD_NONE);
rViewer->setUpViewInWindow(width,height,wm->getWidth(),wm->getHeight());
cam = wm->createParentOrthoCamera();

osg::ClearNode *backdrop = new osg::ClearNode;
backdrop->setClearColor(osg::Vec4(0.1,0.1,0.0,1.0));
cam->addChild(backdrop);

// add event handlers
rViewer->addEventHandler(new osgWidget::MouseHandler(wm));
rViewer->addEventHandler(new osgWidget::KeyboardHandler(wm));

rViewer->realize();
rViewer->setCameraWithFocus(cam);
rViewer->setSceneData(cam);

And I need to be able to close the window dynamically. I implemented this:

osgViewer::Viewer::Windows windows;
rViewer->getWindows(windows);
osgViewer::GraphicsWindow *win = *windows.begin();
win->getEventQueue()->keyPress(osgGA::GUIEventAdapter::KEY_Escape);
win->getEventQueue()->keyRelease(osgGA::GUIEventAdapter::KEY_Escape);

but no joy. If anyone can point me in the right direction I'd be most grateful. 
Thanks in advance!

Re: [osg-users] Multiple Windows, Multiple Screens

[Robert Osfield]

Hi Julen,

It sounds like you have a single View but with two slave cameras, once
slave for each window.  This would mean two graphics context which
will mean a performance and memory overhead.  Sharing contexts would
help on the memory consumption front, but it'd only be safe to run the
view single threaded otherwise the OpenGL objects could get corrupted.

Robert.

[osg-users] Multiple Windows, Multiple Screens

[Julen Garcia]

Hi!

I'm trying to setup a sceneario where in the first display I have a Qt
window with diferent camera buttons and a 640x480 window for preview. The
second screen is supposed to be the output where a fullscreen 1980x1080
window is displayed.


Do I need to use the composite view with two different graphic contexts?

Does this drop the performance too much?

Should I share the graphic context? How?

Thanks in advance,

It's driving me mad...

I tried deactivating things to isolate the problem, then I reactivated
everything to be sure to know where the problem comes from, and all is
working correctly with exactly the same code that was causing the problem,
my SVN repro can prove it. :)

Re: [osg-users] multiple windows rendering bug

[Robert Osfield]

Hi Serge,

The behaviour of the problem sounds a bit like contextID's aren't be
managed correctly.  osgViewer/GraphicsContext should be managing the
contextID automatically for you.  It would be worth double checking by
looking each windows ContextID i.e.

 gc->getState()->getContextID();

You should 0 and 1 respectively for the two windows.

The other possibility might be that your own custom graphics code does
manage multiple graphics contexts properly so tries to reuse texture
objects or display lists from the wrong graphics context.

Robert.

My setup is :

Hi,

Have you tried forcing single threaded?

maybe see this thread.

"Complete garbage in OSG / XP / multi monitor / multi  threaded / NVidia"

Don't know your setup, so I'm guessing.

[Emmanuel Roche]

Hi !

thanks for testing Thibault, if it's working on your side, it's already a
good thing...
I compiled everything in multithreaded DLL, this should be ok... So, as you
suggest, maybe it's a good time to try VS 2005... :-)

Manu.

Hi Emmanuel

I've just compiled your mod, and got the sample running.

I can't reproduce this crash on my machine (VS 2005 SP1), everything
seems to work smoothly.

No, the only reason I did this in the first place is because we would
have no way to spawn the startup page if we closed it - thus we would
not be able to add anymore tabs.
Also, it was a good way to check that we could add any window type as
a tab - not only osg canvas.

I'd bet the problem is a CRT issue. The bugs in wxAUI I had in the
past were always triggered inside wxWidgets when you would remove a
tab, it does not seem to be the case here.
Have you made sure you used the multithreaded DLL everywhere ? (osg
does this by default, wxWidgets needs to be compiled in DLL [Unicode]
mode), and your app must use the multithreaded DLL.
Also make sure you use the correct preprocessor macros (WXUSINGDLL and such).

Bugs that occur at various places are hard to track. One thing you can
do is regularly check the heap to see if a corruption occurs at some
point by using the _heapchk() function. If something goes wrong you
can be notified before the crash occurs (at a random place because the
memory layout changes from execution to execution).

Finally, try to switch to VS 2005 as the compiler (and the C++
runtime) contains much less bugs than VS 7.x series.

Hi again,

I check again the crash: in fact it comes from osgDB::readNodeFile(...) when
it's called the second time (so after a first View is created, added to the
main composite viewer, rendered correctly a few seconds, and then removed
from the composite viewer and destroyed...) : Would you have any clue on
this Robert ?

Manu.

Re: [osg-users] multiple windows

[Emmanuel Roche]

By the way, guys, I've noticed a small bug in this wxOSG_tab application (at
least in the version I compiled...):

Has someone already noticed that, if you remove the "start page" [you then
create the _auiNotebook the first time it is requested] and for example add
a Menu with an "Open..." command to load osg models, then each time you do
this sequence:

1) Open an osg file,
2) Close the only tab created
3) Try to open an other file

... the application crashes...

I put a zip file of the modified sources on my website: if someone wants to
check this... http://utopianworld.ath.cx/web/osg/wxOSG_tab_modified.zip
Or maybe it's a known issue and that's the very reason why you added the
"Start page" and prevented its detruction ?

I can't say if the problem comes from OSG or wxWidgets: sometimes I have a
crash on osgViewer::View constructor but the debug version doesn't display
anything useful, and sometines I have the bug in other dlls like ntdll for
example... if it comes from wxWidgets, maybe that's the reason why you are
using version 2.9 (I built the application with the version 2.8.4, and in
non-unicode... so if you when to test this you may have to make small
changed in the code I added [every thing is in MainFrame.cpp in fact])

regards,
Manu.

That is quite expected. The update traversal is not normally
triggered, so no updatecallback-based animations can work if the view
is not being updated. If you throw the model, the manipulator calls
requestContinuousUpdate(true) so animations are updated.
If you want to override this behavior, you can call
Canvas::setUpdateWhenIdleOverride(true). You'll get the "normal",
real-time OSG loop.

The rationale is that GUI based applications more often display static
scenes (e.g. in a 3D modeler, the update is not continuous).

Re: [osg-users] multiple windows

[Mario Valle]

Nice example, thanks!
I had to make some addition to have it compiling under VS 7.1 (and my wx and osg
libraries). But beside this, I noticed a strange thing:
load spaceship.osg (or fountain.osg) and you notice the motor plumes does not 
animate. If
you make the model rotate, they start animate again.
It is something related to your OnIdle optimization. If you comment the if 
line, then
everything animates as usual.
Hope it helps.
Ciao!

 If the different viewers don't share any GaphicsWindows then it should
 be fine to have multiple Viewer/CompositeViewers.

 However, If all the viewers run in different threads then sharing a
 single scene graph between them would be problematic.  Such usage
 would lead to one viewers update running in parallel with another
 viewer's cull/draw.

Versioning of the dlls is now done by default for the OSG, this is to
prevent you from mixing the wrong version of the OSG at compile time

Whaooo !

Thanks ! thanks ! thanks !...
That's exactly what I was looking for... it's really great ! :-)

just a small point : you're binary distribution is not working : at least
osg24-osgUtil.dll is missing for me :-)

I have osg25-*** on my computer Could someone tell me what this means by
the way ? why this prefix on the dll files ?

But I successfully rebuild your application from the sources with OSG
2.2and wxWidgets
2.8.4 on winXP (with Visual Studio .NET 2003)...
Sorry I don't have a valid linux dev station for the moment.

thanks again... Now I finally have a working example :-)

Re: [osg-users] multiple windows

[Thibault Genessay]

Hi Emmanuel

I have made a sample that demonstrate the integration of the OSG in
wxWidgets. It is a simple frame with a wxAUINotebook containing OSG
views. You can download source and binaries at
http://ips-dil.unil.ch/osg

Could you have a look at these and see if this suits your needs ?

I am planning to release it as an "official" sample to OSG+wxWidgets,
so I'll need to test it on more systems (not tested on Linux as of
today) and more threading models.

It uses a modified version of the osgCompositeViewer::Viewer that
skips rendering if makeCurrent() returns false. Currently, the
composite viewer ignores the return value of makeCurrent(). We'll need
to address this issue with Robert as it is precisely the problem you
and him are discussing in the thread "camera switching in composite
viewer".

Cheers

Thibault

Re: [osg-users] multiple windows

[Emmanuel Roche]

Okay, with this version joined, we have two tabs (not added dynamically,
sure, but it's a beginning...) with animation rendered correctly...

The only issue left is the mouse handling problem:
I added a trackballmanipulator on the view1 on each tab, assigned an
handling function to the corresponding wxGLCanvas each time, and this
function is indeed called when I drag on the view1 BUT nothing moves...
:-(...

I'm using view->getEventQueue()... could it be somehow "disconnected" ?
nothing happens either if I use the corresponding
graphicswindow->getEventQueue()... so what's left ??

Re: [osg-users] multiple windows

Indeed, we are in a situation where the CompositeViewers don't share the
GraphicsWindows and everything happen in the same thread... yet, it's
currently not working for me:

as soon as I had a second tab only the last compositeviewer gets updated and
drawn, the others are frozen... :-(...

I keep investigating...

If the different viewers don't share any GaphicsWindows then it should
be fine to have multiple Viewer/CompositeViewers.

However, If all the viewers run in different threads then sharing a
single scene graph between them would be problematic.  Such usage
would lead to one viewers update running in parallel with another
viewer's cull/draw.

Re: [osg-users] multiple windows

[Emmanuel Roche]

Yes Alberto, you're right, and I noticed this also, that's why my
GraphicsWindowWX class inherits from both wxGLCanvas and
osgViewer::GraphicsWindow as you can see in the files I joined... [this
solution comes from the osgviewerWX example].

And in addition to this you will notice  that I'm not using OnPaint to draw
the GL canvas : because this function is called only when Wx thinks it is
"needed"... I had to use an Idle function instead to handle the
viewer->frame() call often enough.

Concerning the TrackballManipulator issue I noticed that things work well if
I use "view->getEventQueue()" instead of the corresponding
GraphicsWindow->getEventQueue()...

Manu.

PS: ... Writing this, I have an other idea... the very problem comes from
the fact that I'm using an Idle function... but why am I not keeping using
OnPaint and just adding a call o Refresh() at the end !!! ??? :-) I'm
testing this right now...

[Alberto Luaces]

If I recall correctly, you can have as many CompositeViewers as you like/need.

Re: [osg-users] multiple windows

[Alberto Luaces]

Hi Manu,

I have been investigating a bit the event issue an I found some interesting 
things:

The mouse event is only proccessed when the mouse pointer is over a part of 
the wxPanel not owned by a wxGLCanvas, that is, mouse events on the 
wxGLCanvas aren't sent to its parents. According to the Wx documentation, 
only events that are derived from wxCommandEvent are passed to the parents. 
The rest (and here the documentation mentions wxMouseEvent explicitly) 
aren't. So we should have to subclass from wxGLCanvas to handle those events 
after all.

I'll post further progress.

Re: [osg-users] multiple windows

[Emmanuel Roche]

Still on the issue of multi-windows, I guess it's totally unsafe to use
multiple CompositeViewer at the same time, isn't it ?

For exemple doing something like:

CompositeViewer* v1 = (...)

CompositeViewer* v2 = ()


while(true) {
  v1->frame();
  v2->frame();
}


???

Re: [osg-users] multiple windows

[Emmanuel Roche]

For those who would have some time to give a look at this, I'm joining the
code of a simple application designed to open a View in multiple tabs:

the user select an osg or ive file to open an then a new tab is created
using this file as scene Data.

There is a single CompositeViewer managed by the main frame, an 1 View
object per tab...

This sample is NOT working properly: if you add one tab, every thing is
okay, but when you had other tabs, as before, only the last one is displayed
:-( the others become empty [only the default blue background :-( ] and this
last tab doesn't handle the mouse inputs correctly [instead, it seems that
the mouse input for the first tab are used for this last View !!!...

Yet the code is very clear: each tab has its GraphicsWindowWX, (so its
wxGLCanvas too), its OSGPanel (so its own processing of mouse inputs, and
its View).. so what does this mean ? is the global CompositeViewer
appropriating itself the eventQueue of the first View added and then using
this one for the other Views ?

As always , any clue would be really welcomed, I feel a bit lost with
this...

regards,
Manu.

Re: [osg-users] multiple windows

[Emmanuel Roche]

Hi again guys !

I've just tested your solution Alberto, and indeed it's working and I can
see both pages with two View on each page :-)...

Yet I think there is still something I'm missing about the CompositeViewer
behavior : indeed, I set a trackballmanipulator for the view1 [
view1->setCameraManipulator(new osgGA::TrackballManipulator); ] and created
a Mouse handling function:

void ventana::OnMouse(wxMouseEvent& event)
{
if (event.ButtonDown()) {
int button = event.GetButton();
v1->getEventQueue()->mouseButtonPress(event.GetX(), event.GetY(),
button);
}
else if (event.ButtonUp()) {
int button = event.GetButton();
v1->getEventQueue()->mouseButtonRelease(event.GetX(), event.GetY(),
button);
}
else if (event.Dragging()) {
v1->getEventQueue()->mouseMotion(event.GetX(), event.GetY());
}
}

... here "v1" is the first GraphicsWindow on the tab, and, when I activate
this function by dragging the mouse on the tab nothing moves :-(... I
trying replacing "v1" by "cViewer" and calling
cViewer->setEventQueue(v1->getEventQueue()) in the initilialization process
[ because the eventQueue seems to be NULL otherwise...] but this doesn't
work either... Any clue about this ???

Re: [osg-users] multiple windows

[Robert Osfield]

Hi Guys,

I don't have any recommendations, or time right now to dive into this
topic.  I'd certainly like to see osgViewer be able to cope with this
type of usage, and its not one that its been coded for up to this
point.  Might I suggest getting a tabbed WxWidget example together
than could be included with the OSG distribution that illustrates the
this issue and can be used as a test bed for a final recommend
solution.

Robert.

Re: [osg-users] multiple windows

[Emmanuel Roche]

I'm not supposed to control this SetCurrent function : it is called by the
graphicsWindow when it wants to draw a frame()

But indeed, if i were to use multiple osgViewer::Viewer for example instead
of a single CompositeViewer I could process this event to update the
"Current Viewer"... Yet I think I heard somewhere it's not a good idea to
use multiple asynchronous Viewer object in a single application am I
wrong ?

Re: [osg-users] multiple windows

[Alberto Luaces]

Hi Manu,

I'm doing the very same thing, but with two views of a same scene on every 
tab. Currently it works well, but I suspect there are duplicated resources, so 
I have to say that my code is not in its final version.

I'm attaching it, it works for me on Linux and wx 2.6.3 unmodified.

Feel free to compare it with yours so we can learn together :)

HTH,

Alberto

Re: [osg-users] multiple windows

[Andreas Goebel]

Hi,

why don´t you just call SetCurrent when the corresponding tab is shown?

You could process the *EVT_NOTEBOOK_PAGE_CHANGED event and then make the 
corresponding wxGLCanvas that lies in the notebook current.

Andreas

Hello everyone!

I've got a simple question, but I can't find any practical solution:

In my application, I have to display a notebook with a 3D window on each
tab... and I want to be able to add/remove tabs dynamically... so, what can
I use to achieve this result ?

I'm usig wxWidgets + OSG 2.2.0
I'm on Win XP

I tried with a CompositeViewer :
- creating the conpositeViewer when requested (so everything should be in
the wx event handling thread...)
- building my graphicswindowWX
- creating a view
- adding this view to the compositeview
- relying on an Idle function to call viewer->frame()...

... this works as long as there is a single tab...  but when I had others,
then only the last tab added display something : the others only display the
blue background with no model anymore... ? why that ??

by the way I had to make a small change in the
GraphicsWindowWx::makeCurrentImplementation() :

bool GraphicsWindowWX::makeCurrentImplementation() {
  // Bouml preserved body begin 0001FE83
if(!GetParent()->IsShown())
return false;

SetCurrent();
return true;
  // Bouml preserved body end 0001FE83
}

--> So the hidden tabs should return false here... could this be the source
of the problem ?? (anyway wxWidgets doesn't accept SetCurrent() when the
corresponding tab is not visible... :-S )

regards !

Thanks for your help !
Manu.
