Examples of various ways to have OpenGL objects work with C++ RAII.


RAII encapsulation of OpenGL objects has dangers. The most unavoidable is that OpenGL objects are associated with the OpenGL context that created them. So the destruction of a C++ RAII object must be done in a OpenGL context which shares ownership of the OpenGL object managed by that C++ object.

This also means that if all contexts which own the object are destroyed, then any existing RAII encapsulated OpenGL objects will try to destroy objects which no longer exist.

You must take manual steps to deal with context issues like this.
