Constructor & Destructor Documentation

osg::BufferObject::BufferObject (  ) 

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

Copy constructor using CopyOp to manage deep vs shallow copy.

osg::BufferObject::~BufferObject (  )  [protected]


Member Function Documentation

virtual bool osg::BufferObject::isSameKindAs ( const Object obj  )  const [inline, virtual]

Reimplemented from osg::Object.

References NULL.

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 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.

void osg::BufferObject::setTarget ( GLenum  target  )  [inline]

GLenum osg::BufferObject::getTarget (  )  const [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.

GLenum osg::BufferObject::getUsage (  )  const [inline]

Get the type of usage the buffer object has been set up for.

BufferObjectProfile& osg::BufferObject::getProfile (  )  [inline]

const BufferObjectProfile& osg::BufferObject::getProfile (  )  const [inline]

void osg::BufferObject::dirty (  ) 

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::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 osg::BufferObject::addBufferData ( BufferData bd  ) 

void osg::BufferObject::removeBufferData ( unsigned int  index  ) 

void osg::BufferObject::removeBufferData ( BufferData bd  ) 

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

BufferData* osg::BufferObject::getBufferData ( unsigned int  index  )  [inline]

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

unsigned int osg::BufferObject::getNumBufferData (  )  const [inline]

void osg::BufferObject::setGLBufferObject ( unsigned int  contextID,
GLBufferObject glbo 
) [inline]

GLBufferObject* osg::BufferObject::getGLBufferObject ( unsigned int  contextID  )  const [inline]

GLBufferObject* osg::BufferObject::getOrCreateGLBufferObject ( unsigned int  contextID  )  const [inline]

unsigned int osg::BufferObject::computeRequiredBufferSize (  )  const

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

deprecated, provided for backwards compatibility.
