Re: [osg-users] osgViewerQT example question
I'm using the new version, under Linux (although I will eventually be testing under windows as well, I need it to work on Ubuntu first). Like I mentioned, I am trying to extend the example to fit into the QGraphicsView approach. Based on various guides and discussions that I have found, this involves setting the GLWidget as the viewport of the QGraphicsView. In theory, this should let me use the OSG View as the background of the widget, and place QGraphicsItems in a QGraphicsScene that will appear on top of it. I can get this to work using the osgViewer::Viewer, for a single window, but when I try the same approach with a CompositeViewer and multiple windows, I get a variety of errors. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61146#61146 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgViewerQT example question
I've made a couple of attempts, and I feel like I am very close... On one attempt, using a seperate osgViewer for each View, everything works but the Database Pager isn't happy about having multiple viewers looking at the same data. (osgEarth data under PagedLOD nodes flickers in and out of the various levels of detail) On another attempt, using a composite viewer, everything works as I would expect it to if I only have one view, and I am able to add QGraphicsItems to the scene, but if I attempt to add a second View, they get rendered to the same viewport, fighting over it, spit out a bunch of detected invalid value after renderBin draw errors, then crashes. On another attempt, having multiple views works fine, until I add a QGraphicsScene to the graphicsView. The items in the QGraphicsScene will render, but the osg view will not, sending Cannot make context current errors to the console. Across these three failure modes is the set of features I need working; I just need to find the proper way to mesh them together -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=61152#61152 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osgviewerQt example - 3D disappears if Viewer height is zero
So, the problem related to the NaN dump of CullVisitor::apply(Geode) is solved in OSG 3.2.0. On the other side there is still a problem related to the 3d graphics disappearing. This can be easily reproduced with osgviewerQt example. Basically, resizing the viewer to have 0 height then expand it again and the graphics is no more visibe.

[osg-users] osgviewerQt example - 3D disappears if Viewer height is zero
Hi,
in my Qt application I'm experiencing some issues when the viewer is reduced to
0 height. I reduce the viewer size to 0 height then I increase its height again
and when I try to interactively rotate the (no more visible - see below) scene
with mouse (through a trackabll manipulator) I get the following dump on screen:
CullVisitor::apply(Geode) detected NaN,
depth=-1.#IND, center=(35 0 -2.14577e-006),
matrix={
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
1.#QNAN 1.#QNAN 1.#QNAN 1.#QNAN
0 0 -98 1
}
Moreover my 3D scene is not visualized anymore.
So I tried with osgviewerQt example and the 3D scene disappears here too. Is it
a known issue? I'm investigating on it to understand the point but if someone
already found the cause or a solution please let me know.

Re: [osg-users] osgviewerQt example - 3D disappears if Viewer height is zero
Hi Gianni,
The issue sounds vaguely familiar, but I'm afraid I can't recall all
details off the top of my head, or whether it was osgQt specific even.
My guess it'll be an issue with the camera projection matrix being
scaled to 0,0 to fit to zero sized viewport and then once an attempt
to rescale it back up to valid size that erroneous matrix is re-scaled
and of course fails. Adding some debugging in the code that sets the
projection matrix would allow you to spot whether this is happening or
not. One could disable the automatic adjustment of the camera
projection matrix too to see if this is the root of the issue, see
osg::Camera::setProjectionResizePolicy(osg::ProjectionResizePolicy)
method :
From include/osg/Camera:
enum ProjectionResizePolicy
{
FIXED, /** Keep the projection matrix fixed, despite
window resizes.*/
HORIZONTAL, /** Adjust the HORIZONTAL field of view on
window resizes.*/
VERTICAL /** Adjust the VERTICAL field of view on window resizes.*/
};
/** Set the policy used to determine if and how the projection
matrix should be adjusted on window resizes. */
inline void setProjectionResizePolicy(ProjectionResizePolicy
policy) { _projectionResizePolicy = policy; }

[osg-users] osgViewerQt example with Qt signal/slot system
Hi everyone, I'm trying to modify the osgViewerQt example by adding a new class of my own that will contain the viewer. The design is: wrapper.h: Defines class Wrapper. It inherits from QMainWindow and has a QDockWidget where the ViewerWidget will be attached. viewer.h: Defines ViewerWidget class. It's the class from the example, with a few mods by me. prueba_osg.cpp: Main function and where a QApplication is created. A Wrapper object is created here. The project compiles, but when I execute it, I get an error: QWidget: Must construct a QApplication before a QPaintDevice If I remove the Q_OBJECT line, the signal and the slot from wrapper.h and compile the files from the terminal using g++ -IE:/osg-3.0.1/install/include -LE:/osg-3.0.1/install/bin -IC:/Qt64/4.8/include -LC:/Qt64/4.8/bin -losgViewer -lOpenThreads -losgDB -losg -losgGA -losgQt -lQtCore4 -lQtGui4 prueba_qt.cpp I can execute the app. Can you please tell me what can I do to make this work?

Re: [osg-users] osgviewerQt-Example
This is what I think: o You're creating a new QWidget; QTOSG - this is your toplevel Widget o You're then creating a new GLWidget (created by osgQt::GraphicsWindowQt(traits), but it's not connected to the QTOSG widget. - You now have two twolevel widgets. Try modifying your code so that you can do this: traits-inheritedWindowData = new osgQt::GraphicsWindowQt::WindowData(NULL, yourQTOSGwidget); This should connect the two together. You might need to apply the WindowData patch I submitted to the submissions mailing list for this to work. These problems was the exact reason why I decided to write a widget from scratch..

Re: [osg-users] osgviewerQT example
I looked into some odd behavior with an OSG/Qt based application at my place and traced this behavior back to an old favorite... osgviewerQT --QOSGWidget cow.osg This crashes on some systems, runs fine on others. This seems to be true for both OSG versions 2.8.1-rc2 and 2.9.2, Qt version 4.4.3 . We crash soon after we get a message: OpenGL version test failed, requires valid graphics context. Since there is no context glGetString returns NULL and we crash in osg::some class::Extensions::setupGLExtensions. Crashes on these systems: ghanima - SUSE LINUX 10.0 (X86-64) Quadro FX 4500 / PCI / SSE2 2.0.0 NVIDIA 76.67 bubba - Red Hat Enterprise Linux Client release 5 (Tikanga) X86-64 Quadro FX 4500 / PCI / SSE2 2.1.1 NVIDIA 100.14.19 cartman - Red Hat Enterprise Linux WS release 4 (Nahant) Quadro FX 3450/4000 SDI / PCI / SSE2 2.0.0 NVIDIA 76.76 There is no problem with the same test on these systems: dilbert - SUSE LINUX 10.1 (X86-64) Quadro FX 3400 / PCI / SSE2 2.1.2 NVIDIA 180.29 jeckle - SUSE LINUX Enterprise Server 9 (x86_64) Quadro FX 1100 / APG / SSE2 1.5.2 NVIDIA 66.29 curly - Red Hat Enterprise Linux WS release 4 (Nahant) FireGL V3100 1.3.5140 (X4.3.0-8.14.13) loki - Mac OS X 10.5.2 NVIDIA GeForce 7300 GT OpenGL Engine 2.0 NVIDIA-1.5.2 With OSG_WINDOWING_SYSTEM=Carbon. When OSG_WINDOWING_SYSTEM=X11 the programs launches two windows, one with rendering, the other white with window controls. (We haven't done a Windows build in a while, but had this examples working once upon a time.) Digging a bit deeper I found that glXMakeCurrent was failing, but without setting any gl error code. This was after glXCreateContext returned a valid result. If I make this change in QOSGWidget::createContext() ... // traits-inheritedWindowData = new WindowData(winId()); traits-inheritedWindowData = NULL; we no longer crash, but there are now two windows -- one live and one stale, much like the version on Mac with OSG_WINDOWING_SYSTEM=X11. A check of OpenGL doc indicated that there are legitimate reasons for glXMakeCurrent and glXMakeContextCurrent return false without an error. It would seem likely that Qt is creating a Window that is rejected by glXMakeCurrent some of the time. I'm not familiar with Qt source enough to debug that side of the problem. Does this sound like I'm on the right track? Anyone have a suggestion how to fix this on the OSG side? -Don Leich ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] osgviewerQT example
Hi Scott, I've been trying to use the ViewerQT portion of osgviewerQT example. Has anyone been able to get the ViewerQT class to work when the threading model is set to osgViewer::Viewer::ThreadPerContext instead of single threaded? ViewerQT subclasses AdapterWidget, which uses GraphicsWindowEmbedded. This forces you into SingleThreaded mode. Read up in the archives about GraphicsWindowEmbedded to find out why that is. The solution is to use QOSGWidget / ViewerQOSG which is demonstrated in the same example, and can be used with all threading models (which is what we do).

[osg-users] osgviewerQT example
Hi all, I would like to know if in a correctly configured Linux, the osgviewerQT example works with the --QOSGWidget option ? I am asking that because we are currently trying to achieve something similar with WinForms on Linux (using Mono), and we are following the same way than the QT example and the QOSGWidget. The big deal is that we are working with VMWare, without real graphics drivers, and this example crash the same way as our application. That's why we would like to know if it's related to VMWare or not. Thanks in advance ! -- Serge Lages http://www.tharsis-software.com ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] osgviewerQT example requires Qt 4.3
After a recent recompile osgviewerQT fails to compile against Qt4.2, complaining about missing QMdiArea and friends in AdapterWidget.cpp. These classes were introduced in Qt4.3 according to Trolltech's site (http://doc.trolltech.com/4.3/qmdiarea.html). It looks like OSG's Cmake config doesn't check for Qt4.3, only for a version of Qt 4.
