As a general note, there isn't a big difference between single | |||
threaded and multithread usage of the OSG in terms of OpenGL dispatch, | |||
with two separate windows there should be two separate graphics | |||
contexts and it should make no difference if you drive these from one | |||
thread one two, the state for each context should be kept local to | |||
each one.<ref>https://www.mail-archive.com/osg-users@lists.openscenegraph.org/msg03788.html</ref> | |||
* osgViewer::CompositeViewer is designed for applications that have multiple Views. The only thing to be careful of is when you are adding and removing View's from the CompositeViewer you should do is calling stopThreading() on the viewer prior to adding or removing views, then call startThreading() afterwards. If you are running SingleThreaded or CullDrawThreadPerContext you won't need to worry about stop and starting threads.<ref>https://groups.google.com/d/msg/osg-users/7OojxLpBGdw/mzorZe3rKwEJ</ref> | * osgViewer::CompositeViewer is designed for applications that have multiple Views.
