Detailed Description

template<class T>
class eq::util::ObjectManager< T >

A facility class to manage OpenGL objects across shared contexts.

The object manager implements object sharing in the same way as OpenGL. During creation, a shared object manager may be given, causing the two (or more) object managers to allocate objects from the same namespace. The last object manager will delete all data allocated on the host. OpenGL objects have to be explictly deleted using deleteAll() to ensure an OpenGL context is still current during destruction.

For each type of OpenGL object supported the following methods are available:
