Hi all,
I'm new to OpenSG and I'm trying to use a shared OpenGL Object between multiple OpenGL Contexts,
that is I want to share a 3D Texture between 2 different contexts ( OpenSG windows based on Qt QGLWidget ).
I've already read the OpenSG Official Online Documentation about "OpenGL Objects & Extension Handling"
(
http://www.opensg.org/doc-1.4.0/PageSystemOGLObjects.html ),
and it seems that OpenSG supports the sharing of OpenGL Objects using a static registration procedure.
Unfortunately I've tried to follow the instructions to register and use a 3D Texture between my 2 contexts but it doesn't work,
or better, only the context that create the texture can use it while the other context (t hat has to share the same texture ) cannot.
Moreover I've also seen the other messages posted in date 2006/09/20
(
http://www.mail-archive.com/[email protected]/msg06129.html
)
and from the replies it seems that the sharing of OpenGL Objects still remain an unsolved problem.
Could anyone help me posting a basic example on how to share an OpenGL Object in OpenSG ?
I'm using : OpenSG
1.6 Qt 4.1.4 Win XP C++
Thank you in advance for your help.
G.
