Detailed Description

Encapsulates the current applied OpenGL modes, attributes and vertex arrays settings, implements lazy state updating and provides accessors for querying the current state.

The venerable Red Book says that "OpenGL is a state machine", and this class represents the OpenGL state in OSG. Furthermore, State also has other important features:

It works as a stack of states (see pushStateSet() and popStateSet()). Manipulating this stack of OpenGL states manually is seldom needed, since OSG does this in the most common situations.
It implements lazy state updating. This means that, if one requests a state change and that particular state is already in the requested state, no OpenGL call will be made. This ensures that the OpenGL pipeline is not stalled by unnecessary state changes.
It allows to query the current OpenGL state without calls to glGet*(), which typically stall the graphics pipeline (see, for instance, captureCurrentState() and getModelViewMatrix()).

Member Enumeration Documentation

enum osg::State::CheckForGLErrors

Enumerator
NEVER_CHECK_GL_ERRORS	NEVER_CHECK_GL_ERRORS hints that OpenGL need not be checked for, this is the fastest option since checking for errors does incur a small overhead.
ONCE_PER_FRAME	ONCE_PER_FRAME means that OpenGL errors will be checked for once per frame, the overhead is still small, but at least OpenGL errors that are occurring will be caught, the reporting isn't fine grained enough for debugging purposes.
ONCE_PER_ATTRIBUTE	ONCE_PER_ATTRIBUTE means that OpenGL errors will be checked for after every attribute is applied, allow errors to be directly associated with particular operations which makes debugging much easier.

note, if you have an osg::StateAttribute which you have applied externally then use the have_applied(attribute) method as this will the osg::State to track the current state more accurately and enable lazy state updating such that only changed state will be applied.

void osg::State::setContextID ( unsigned int contextID )

inline

Set the current OpenGL context uniqueID.

The ContextID simply acts as an index into arrays that these classes maintain for the purpose of storing GL object handles.

Note, osgViewer::GraphicsWindow will automatically set up the ContextID for you, so you will rearely need to set this yourself.

The exception is when creating your own graphics context, where you should set the ContextID uniquely for each graphics context.

Typical settings for ContextID are 0,1,2,3... up to the maximum number of graphics contexts you have set up. By default contextID is 0.
