Hi, Robert, Alistair
Thanks for your replies.
I've seen osghud example, but that one has no clickable elements on the HUD
camera. I've tried looking into osgpick example aswell, as it looks more
suitable for my needs (with clickable buttons), but the thing is I have to use

scenario of moving a window between two screens to force a

I want to use an osgWidget to draw a compass. So, I need to use the rotation.
The problem is that the origin of the osgWidget is at the bottom left and not
at the center of the widget.
How can I specify the center of my widget (since set Origin only move the
widget) in order to have a
Hi Robert,
Thank you for your answer.
I've tried and set the sharedContext member to 0 for all views,
as you've suggested.
The result was the same, corrupted polygons in one or more views.
But now with the difference that shaders work only in one view, which
is the one first created.
Maybe there
Hi,
Anybody working on basic compute shader integration? Just the new shader type
and a way to kick off the job using DispatchCompute would be awesome.
Might look into this next month if nobody is up for it.

Hi Carsten,
In principle what you are doing should work, what might be wrong I
can't say though. I don't use windows so can't comment on the
specifics of this type of setup. The only thing I can think of that
might cause one window to work but others not is for the OpenGL object
management to
I'll try that out.

Hi, Dario,
LispSM is setup by default to cast shadows using light space backfacing
polygons. That approach works well if models are closed and build with face
culling in mind. If your model does not utilize cull faces (and your truck
looks like that case), all front polygons will cast shadows. So
I tried it out now.
Windows are appearing, and shaders work on each view.
But polygon corruption still persists.
It seems to me that this is a driver issue.

After checking the osg::Program serializer, I can confirm this is a

The community projects page has a blog layout, so you have to add a new
