Re: [osg-users] osgQt + OSG 3.6.2 Status
Hi Andrew, I had no luck despite trying many variations. I had to put this work aside for a while with the plan to circle back and check for osgQt updates now and then. But if someone adds some ideas here I'll try them. To be honest I'm experimenting with Qt3D (feels a little dirty ;-). I know I won't get OSG performance out of it but the reduced Qt integration, Qt5, multithreading, and packaging hassles might make this a viable alternative soon. Qt3D has its own headaches, of course, and is still fairly immature. Maybe I can join a support group for OSG users with a wandering eye.

Hi Stuart, If you resolve this please let us know. As a data point , I had a lot of trouble with OSG 3.4.1 and QT 5.7 and the "black" window problem.

Re: [osg-users] [Crash issue] How to add drawable (geometry) property.
Hi Jinh,
First thing I would try is to run your application single threaded.
If this fixes the crash then it would indicate a threading issue with
how you are going about adding/remove elements of the scene graph.
You don't describe any of details of what threads are doing what so I
can't speculate any further as to what you might be doing wrong. As a
general guide, the OSG is designed for the main scene graph to be
updated only in the update and event phases/traversals where the scene
graph itself is being traversed single threaded.
Robert.

Re: [osg-users] osgSim::MultiSwitch Serialization
HI David,
I'm don't have time to look at the code right now so will just provide
some general hints. The serailizers have SO version built into them
so you can add or remove components of the serializer based on the SO
version of the OSG. There are number of places in the OSG serailizers
that you can look at for inspiration, for instance
src/osgWrappers/serializers/Node.cpp has:
ADD_USER_SERIALIZER( Descriptions ); // _descriptions, deprecated
{
UPDATE_TO_VERSION_SCOPED( 77 )
REMOVE_SERIALIZER( Descriptions );
}
Have a search through the serializers to see the
UPDATE_TO_VERSION_SCOPED used in various ways.
Robert.

Re: [osg-users] Volume rendering issues...
Hi Tom.
My best guess would be that the ITK image data is being deleted prior
to the graphics thread gets a chance copy the data into OpenGL. Try
either copying the data into the osg::Image and let osg::Image then
manage the lifetime of it's own data, or prevent the ITK image data
from getting deleted prior to the osg::Texture3D being used in the
graphics thread - for instance keeping the ITK image object around for
the lifetime of the app, or perhaps more elegantly assigning the ITK
image data via a adapter class that you write to assign it to the
osg:Image as user data.

[osg-users] [Crash issue] How to add drawable (geometry) property.
Hi,
I am doing them real-time rendering application development with Qt + OSG.
I created several threads to create new Geometry and in GUI - main threads, try
to remove the old one and add new ones.
1, already set node and geometry to user dynamic.
geometry->setDataVariance(osg::Object::DYNAMIC)
geode_->setDataVariance(osg::Object::DYNAMIC);
2, already used osg smart point everywhere.
3, geometry is created in other threads. and post to a global queue.
4, in Main thread. PaintGL event will add geometry in "autoAddRemove"
function.
void OSGMeshRender::paintGL() {
autoAddRemove();
viewer_->frame();
}
5, the setup work for qt+osg is almost same like this blog, nothing speical.
vicrucann.github.io/tutorials/cmake-qt-osg-1/
I got below crash sometimes when I add drawable.

[osg-users] Volume rendering issues...
Hi gang,
Thanks for all the work on OSG, is rad. I'm currently having a problem with the
rendering of a volume, here's what I'm trying to do:
- I'm using ITK to read a NIFTI file, (segmentation of a bone). The file
contains zeros (background) and ones (object), format is unsigned short.
- I am then normalizing/scaling this and converting it to an osg::Image.
- I am then attempting to convert this to an osgVolume and display an
iso-surface, or at this stage any kind of volume rendering.
- All the reading, conversion etc. seems to work okay, but I'm getting a read
access violation on line 408 of Texture3d.cpp (specifically:Exception thrown at
0x7FFE64D576B0 (ig9icd64.dll) in RobotSimulation.exe: 0xC005: Access
violation reading location 0x02F5732EE070.)
I'm pretty sure I'm just forgetting something very obvious, but if anyone could
point out what it is that I'm doing wrong that would be much appreciated. I've
put a cut down example of the code below (pretty rough).
I know that the data is definitely in the osg::image object (wrote it to file,
calculated min and max), so I don't necessarily think the conversion is the
problem (though could very well be wrong). I'm on a Windows 10 laptop, with a
built in Intel graphics card (Intel HD Graphics 620, drivers are up to date),
opengl is version 4.5.
Thanks very much for the help, let me know if you need any other info. Cheers,
Tom

more or less the same for any data loaded through ITK and converted to OSG.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Ale, The KdTree was refactored in 3.6.x to add support for points and lines and PolytopeIntersector. While there has been lots of internal changes in it, it of course shouldn't crash. At this point in time I don't have any idea where the issue stems from. Could you create a small example that reproduces the crash, I or others can then step through what is happening and work out a fix. Given this regression it looks like we'll have to make a 3.6.3 sooner rather than later, but not before we fix the crash... Cheers, Robert.

[osg-users] RayIntersector with KdTree causes a crash
Hi, we have a problem with OSG 3.6.2 and Visual Studio 2017 We have a pick functionality in our software that uses RayIntersector. We enabled KdTrees for this use. When we apply the intersector to an object with a negative scale in the MatrixTransform parent node (e.g. scale = (-1, 1, 1)), it crashes inside the KdTree code. If we disable kdtree everything works fine. It also works with Visual Studio 2013 and OSG 3.4.0.

[osg-users] RayIntersector with KdTree causes a crash
Hi, we have a problem with OSG 3.6.2 and Visual Studio 2017 We have a pick functionality in our software that uses RayIntersector. We enabled KdTrees for this use.
