class SG_EXPORT osg::Multisample

Multisample - encapsulates the OpenGL Multisample state

Inheritance:

Public Classes

enum Mode

class SG_EXPORT Extensions: public osg::Referenced

Extensions class which encapsulates the querring of extensions and associated function pointers, and provide convinience wrappers to check for the extensions or use the associated functions

Public Methods

Multisample()

Multisample(const Multisample& trans, const CopyOp& copyop=CopyOp::SHALLOW_COPY)

Copy constructor using CopyOp to manage deep vs shallow copy

META_StateAttribute(osg, Multisample, MULTISAMPLE)

virtual int compare(const StateAttribute& sa) const

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

void setSampleCoverage(float coverage, bool invert)

inline float getCoverage() const

inline bool getInvert() const

inline void setHint(Mode mode)

virtual void apply(State& state) const

static Extensions* getExtensions(unsigned int contextID, bool createIfNotInitalized)

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

static void setExtensions(unsigned int contextID, Extensions* extensions)

setExtensions allows users to override the extensions across graphics contexts.

static Extensions* getExtensions(unsigned int contextID, bool createIfNotInitalized)

Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created then 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 only be created with the graphics context associated with ContextID..

static void setExtensions(unsigned int contextID, Extensions* extensions)

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.
