Member Function Documentation

unsigned int osg::BufferObject::addBufferData ( BufferData bd)
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.

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

deprecated, provided for backwards compatibility.

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

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

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

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

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.

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.

void osg::BufferObject::removeBufferData ( 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.
