[osg-users] Some questions on osgWidget's double click

[Mooneast]

Questions are as following :
 To the class osgWidget , there're many event callback funtion applyed to 
support its availability except the double click event . So can I get your 
consideration on this operation ?
 And on the other hand , I have tried the way to replace the double click with 
two quick clicks . 
 But in the process , I find that OSG thinks the two quick clicks as two clicks 
when the interval between them is enough soon .
 And from the source code , I can't find the reason , and can you please give 
some suggestion ? I'm a new hand from China in OSG development , and my name is 
Jordan Lee .
 Thank you anyway !___

[osg-users] osgDB::ReentrantMutex ?

[Trajce Nikolov NICK]

Hi Community,

I am upgrading the txp plugin from the latest code drop from Presagis and
it seam it is really out of date (1.somthing is the osg used). Anyone can
recall osgDB::ReentrantMutex and why it is not available anymore?

Thanks for any hint

Nick

Re: [osg-users] Viewer QT Freeze (refresh problem).

[Dario Minieri]

Hi Robert

In your QT viewer example you have 5 statics scenes. A single viewer shows a 
single object and never changes: you update the widgets using a QTimer. 

Now, I have a dynamic system where the scene graph changes continuously and 
there is OsgOcean. I think that the QT problem is the next: If I change the 
scene graph tree when QT updates the viewer QGLWidget (paintGL() calls a new 
frame()), there is a race condition.

The chain is: 

1. I make osg tree scene changes.
2. I call the QWidget::update() which call the relative paintGL() slot.
3. paintGL() slot call the osg frame(). 

This slot (paintGL()) is asynchronous (means we have no garantees when the 
paintGL() comes...), so I can return to change the osg scene tree again even if 
the frame() (an "old" frame() call) is still in execution. I have tried to use 
a mutex but without luck at now.  The crash report is next:

You can suggest to me some example to look, using QTViewer and dynamics scenes?

Thank you!

Cheers,
Dario

Re: [osg-users] OpenGL 3.2 support in OS X 10.7 (Lion)

[Robert Osfield]

Hi Roman,

I'm currently looking through my archives for pending submissions and
spotted this post from you, it was never formally addressed as a
submission though, is it intended to be merged?  Could you get things
working under svn/trunk and send me the whole files zipped up to avoid
the forum mangling the attachments.

Thanks,
Robert.

Re: [osg-users] adding barrel distortion for stereoscopic rendering in Oculus Rift head set

[Roy Arents]

Hi,

Jeff (jbail) pm'd me as his post is not approved yet. He has posted some code 
on the Oculus developer forum: 

https://developer.oculusvr.com/forums/viewtopic.php?f=39&t=1885&sid=4a751a276c8632e6671109c636244188
 

I did not tested it myself, but it looks great! Until his reply gets approved, 
he asked me to post this link here on his behalf. Hopefully this can get 
everyone started and we take osg/oculus to the next level

Thank you!

Cheers,
Roy
