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.

Member Function Documentation

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

apply the OpenGL state attributes.

The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from 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]
static Extensions* osg::Multisample::getExtensions ( unsigned int  contextID,
bool  createIfNotInitalized 
) [static]

Function to call to get the extension of a specified context.

If the Extension 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..

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