Hi,
My osgGa::NodeTrackerManipulator crashes if it is activated before
setTrackNode(..) is called.
Do I make a mistake or is the NodeTrackerManipulator not secured against
activation prior to a well defined node to track?
Thank you!
Cheers,
Torben

Hi Torben,
The manipulator shouldn't crash so this will be bug due to an
assumption of having a valid nodepath somewhere in the code.
Do you have a stack trace for the crash? Which version of the OSG are
you using?
Robert.

Hi All,
I'm trying to understand osgWidget library and I have a basic question.
In the related examples I see an osgWidget::WindowManager instance is created
on the heap but never deleted explicitly. Is the associated viewer responsible
of the WindowManager deletion or should I delete it
Hi Robert,
The stack trace is:
Code:
osg71-osgGAd.dll!std::_Vector_const_iteratorosg::Node
*,std::allocatorosg::Node * ::operator+=(int _Off=-1) Zeile 161 + 0x60
Bytes C++
osg71-osgGAd.dll!std::_Vector_iteratorosg::Node
*,std::allocatorosg::Node * ::operator+=(int _Off=-1)
Hi Torben Mourad,
I have added a check against the getNodePath() being empty() to
computeNodeCenterAndRotation() method and checked it into svn/trunk.
The relevant code now looks like:
osg::NodePath nodePath;
if (_trackNodePath.getNodePath(nodePath) !nodePath.empty())
ok, solved!
thank you!!!

In attachment osg file that doesn't work. When I activate osgShadow, I can't
see texture.
In osg file there's field textureUnit 0 {}. If I remove this and change,
texture works.

Hi All,
is there a root node for all widgets inserted in a WindowManager?
I mean, I use a root node for 3D objects in my viewer and I would like to have
the same feature for widgets. In fact in my scene manager I store a Group node
to which I add all other nodes without using a viewer pointer

Thanks. I'm getting the error Error: glGenBuffers not supported by OpenGL

Error: glBindBuffer/glBufferData not supported by OpenGL driver. Is it the

Hi Vijeesh,
I a bit surprised by these errors, is this still in the context of VPB
usage? VPB shouldn't be touching glGenBuffers/glBindBuffers during
execution.
What drivers/hardware are you working with?

Hello OSGers!
I was wondering what kind of mechanisms OSG currently has, or if there is a
plugin, that would allow warping the ranges of predetermined LOD/Tiles from

Just one more consideration.
In other examples (i.e. osgwidgetlabel) the window manager is not added as
child of the camera but createParentOrthoCamera() is used insted. Looking at
that code the Window Manager is internally added to the returned camera.

You could probably do it by overriding the cullvisitor and accepting nodes
farther out in front of your motion vector.

One could use a ReadFileCallback to modify PagedLOD attaching custom

I'd like to port GraphicsWindowWin32 and PixelBufferWin32 to work on EGL as
well as WGL. I'd use the PVRVFrame EGL libraries as the target for the port.
