[osg-users] Add / Remove Slave
Hi i am wondering who i can add / remove slave cameras at runtime. with different rendering context, embeded full screen, on different screens. I get opengl state bugs, do i need to share opengl from master camera ? can i not remove the very master camera? or what is the correct concept. adrian -- Adrian Egli ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Add / Remove Slave
Hi Adrian, If you want to add and remove slaves from a view at runtime you will need to stop the threading of the viewer via viewer.stopThreading(), then add/removeSlave() call realize on any new graphics contexts then call startThreading(); Robert.

Re: [osg-users] Add / Remove Slave
Hi Adrian, i share the context, when i remove the slave, i will loose all textures (:-)) This has been discussed a lot in the past, search the archives. Hint: disable "unref textures on apply".

Re: [osg-users] Add / Remove Slave
Thanks for the replay, but i can not find any topic corresponding this contex. I don't know what's going wrong, but if i share an openGL context, say from my master camera and then i suddenly like to close a slave cam, i shouldn't close the shared context. because i still have the current context in use, right? It doesn't delete the master's context, but i loose the textures, may this is what your like to give as hint. but i am not sure whether it removes the textures only. /adrian 2009/1/21 Jean-Sébastien Guay > Hi Adrian, > > i share the context, when i remove the slave, i will loose all textures >> (:-)) >> > > This has been discussed a lot in the past, search the archives.

Re: [osg-users] Add / Remove Slave
Hi Adrian, The problem might well be that the outgoing context is cleaning up it's scene graph and associated OpenGL without know that they are shared. You could remove the scene graph from the associated camera before closing it to prevent the graphics window automatically cleanly up all associate OpenGL objects. Robert.

Re: [osg-users] Add / Remove Slave
100% right Robert, removing the scene data before closing the context solves
the problem
The code above should help others having similar issue in the future...

m_IWebaddon3D->getWebaddonRenderer()->getOSGViewer()->stopThreading();
if ( ! m_isFullScreen) {
setupSlaves();

osg::View::Slave &slave =
m_IWebaddon3D->getWebaddonRenderer()->getOSGViewer()->getSlave(*it);
slave._camera->removeChildren(0,slave._camera->getNumChildren());
slave._camera->addChild(m_IWebaddon3D->getWebaddonRenderer()->getOSGViewer()->getSceneData());
}
} else {
