osg::BufferObject::BufferObject	(	const BufferObject &	bo,
		const CopyOp &	copyop = CopyOp::SHALLOW_COPY

void osg::BufferObject::bindBuffer

(

unsigned int

contextID

)

const [inline]

GLuint& osg::BufferObject::buffer

(

unsigned int

contextID

)

const [inline]

virtual const char* osg::BufferObject::className

(

)

const [inline, virtual]

return the name of the object's class type. Must be defined by derived classes.

Implements osg::Object.

virtual void osg::BufferObject::compileBuffer

(

State &

state

)

const [pure virtual]

Implemented in osg::PixelBufferObject.

static void osg::BufferObject::deleteBufferObject	(	unsigned int	contextID,
		GLuint	globj
	)			[static]

Use deleteVertexBufferObject instead of glDeleteBuffers to allow OpenGL buffer objects to be cached until they can be deleted by the OpenGL context in which they were created, specified by contextID.

void osg::BufferObject::flushDeletedBufferObjects	(	unsigned int	contextID,
		double	,
		double &	availableTime
	)

flush all the cached display list which need to be deleted in the OpenGL context related to contextID.

static Extensions* osg::BufferObject::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 is only created with the graphics context associated with ContextID..

bool osg::BufferObject::isBufferObjectSupported

(

unsigned int

contextID

)

const [inline]

bool osg::BufferObject::isPBOSupported

(

unsigned int

contextID

)

const [inline]

virtual bool osg::BufferObject::isSameKindAs

(

const Object *

obj

)

const [inline, virtual]

Reimplemented from osg::Object.

virtual const char* osg::BufferObject::libraryName

(

)

const [inline, virtual]

return the name of the object's library. Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Implements osg::Object.

virtual bool osg::BufferObject::needsCompile

(

unsigned int

contextID

)

const [pure virtual]

Implemented in osg::PixelBufferObject.

void osg::BufferObject::releaseBuffer

(

State *

state

)

const

static void osg::BufferObject::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.

void osg::BufferObject::unbindBuffer

(

unsigned int

contextID

)

const [inline]
