const BufferData* osg::BufferObject::getBufferData ( unsigned int  index ) const

inline

bool osg::BufferObject::getCopyDataAndReleaseGLBufferObject ( ) const

inline

Get whether the BufferObject should use a GLBufferObject just for copying the BufferData and release it immmediately.

virtual bool osg::BufferObject::isSameKindAs ( const Object *  obj ) const

inlinevirtual

Reimplemented from osg::Object.

References NULL.

virtual const char* osg::BufferObject::libraryName ( ) const

inlinevirtual

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.

void osg::BufferObject::releaseGLObjects ( State *  state = 0 ) const

virtual

If State is non-zero, this function releases OpenGL objects for the specified graphics context. Otherwise, releases OpenGL objects for all graphics contexts.

Reimplemented from osg::Object.

(

unsigned int

index

)

void osg::BufferObject::removeBufferData

(

BufferData *

bd

)

virtual void osg::BufferObject::resizeGLObjectBuffers ( unsigned int  maxSize )

virtual

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::Object.

Reimplemented in osg::PixelDataBufferObject.

void osg::BufferObject::setBufferData	(	unsigned int	index,
		BufferData *	bd
	)

void osg::BufferObject::setCopyDataAndReleaseGLBufferObject ( bool  copyAndRelease )

inline

Set whether the BufferObject should use a GLBufferObject just for copying the BufferData and release it immmediately so that it may be reused.

void osg::BufferObject::setGLBufferObject ( unsigned int  contextID, GLBufferObject *  glbo  )

inline

void osg::BufferObject::setTarget ( GLenum  target )

inline

void osg::BufferObject::setUsage ( GLenum  usage )

inline

Set what type of usage the buffer object will have. Options are: GL_STREAM_DRAW, GL_STREAM_READ, GL_STREAM_COPY, GL_STATIC_DRAW, GL_STATIC_READ, GL_STATIC_COPY, GL_DYNAMIC_DRAW, GL_DYNAMIC_READ, or GL_DYNAMIC_COPY.
