Constructor & Destructor Documentation

osg::Multisample::Multisample ( )

osg::Multisample::Multisample ( const Multisample & trans,

const CopyOp & copyop = CopyOp::SHALLOW_COPY

) [inline]

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::Multisample::~Multisample ( ) [protected, virtual]

Member Function Documentation

virtual void osg::Multisample::apply ( State & state ) const [virtual]

apply the OpenGL state attributes.
The global state for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.
Implements osg::StateAttribute.

virtual int osg::Multisample::compare ( const StateAttribute & sa ) const [inline, virtual]

return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

float osg::Multisample::getCoverage ( ) const [inline]

Extensions* osg::Multisample::getExtensions ( unsigned int contextID,

bool createIfNotInitalized

) [static]

Function to call to get the extension of a specified context.
If the Exentsion object for that context has not yet been created and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object will only be created with the graphics context associated with ContextID..

bool osg::Multisample::getInvert ( ) const [inline]

osg::Multisample::META_StateAttribute ( osg ,

Multisample ,

MULTISAMPLE

)

void osg::Multisample::setCoverage ( float coverage ) [inline]

void osg::Multisample::setExtensions ( unsigned int contextID,

Extensions * extensions

) [static]

setExtensions allows users to override the extensions across graphics contexts.
Typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
