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
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. I only
resolved it with some experimentation and I am still not sure why it worked.

Hi Robert,
thanks a lot! I tried single thread, but it can meet project requirement,
as we may have 500+ meshes need to update. each mesh has 12000+ points. the
main GUI thread will be blocked for 10+ seconds
besides, I already set the viewer to use SingleThreaded. paste my code of

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 specula
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 yo
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 de
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::DYN
osgSim::MultiSwitch and flt files support named switches, but the names aren't
saved. It seems like an easy fix, though I'm not sure how to mess with the
serializer in a backwards compatible way.

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
After creation of a GLWidget/QWidget i call setMaximumSize() with a resolution
less than fullscreen.
When i click on the maximize button of the window bar my window is resized to
maximum size but in frameless mode.
Dont know if this is a osg related bug, but i think in qt the maximize event is
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 tha
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.
