Hi. Nice work. How about non-FFP version?

[osg-users] IITSEC this month

[Chris Hanson]

  So, I'll be at IITSEC in Orlando the week of Nov 27 - Dec 1. Won't be
exhibiting in a booth but will be meeting with other clients and
OSG/osgEarth users.

  I'll personally be around Tuesday the 28th through Friday the 1st. If any
other OSG users are going to be there, we should casually meet up and chat.
The last time we chatted about OSG, osgEarth, OpenIG, SunDog's Silver
Lining and Triton (Frank Kane of SunDog is from the Orlando area so he is
always around).

  Looking forward to catching up with anyone who will be in town for the
event.

[osg-users] Draw thread per opengl context instead of per GraphicsContext

[Ben Meijering]

Hi everyone,

I want to use the GraphicsContext::Traits::sharedContext to render multiple 
views (in multiple windows) that share the same context.

I already read on some forums that the ThreadingModel::SingleThreaded  should 
be used.

However, I would still like to use ThreadingModel::DrawThreadPerContext so that 
the cull and draw thread can overlap.

I tried this, but a draw thread is created per GraphicsContext and thus per 
window. Because all these windows share an opengl context, I would have 
expected that only 1 thread would have been created.

This results in all sorts of problems.

Is there a way in which I can use 1 draw thread per opengl context ?
And, if not, is this something that I can easily change by modifying the code ?

Thank you!

Cheers,
Ben

[osg-users] [3rdparty] ImGui integration

[Florian GOLESTIN]

Hi team,

I integrated DearImGui into OpenSceneGraph. 
I forked the Gist from Megaton. You can find my version here: 
https://gist.github.com/fulezi/d2442ca7626bf270226014501357042c.

Features:

Integrated with the OpenGL fixed pipeline
Works with ASCII char and special keys (Control, alt, Super, Shift, enter)
Partial integration of the UTF-8 keyboard (you can type 'ç' but not 'ê', it 
will result as '^e')
Referenced ImGuiCallBack

To Do:
Mouse scroll
(or not to do) Clipboard


Have a good day,
Florian[/url][/list]

Re: [osg-users] osgoculus viewer picking

[Michael Maurus]

Okay, here a few updates of what I learned:

1. There is no geometry which will be rendered to the main camera of 
ogoculusviewer. That's why no intersections can be found.
2. Displaying the oculus view will be done by blitting the mirrorTexture to the 
back buffer.
3. So solve my problem, I added a third slave camera which renders the scene in 
user-friendly mode (different projection matrix than oculus). As this slave 
camera does not RTT picking in window coordinates works fine!

Cheers,
Michael
