osg::BufferObject::BufferObject | ( | const BufferObject & | bo, |
const CopyOp & | copyop = CopyOp::SHALLOW_COPY |
||
) |
Copy constructor using CopyOp to manage deep vs shallow copy.

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.

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 [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 | ) |
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.

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.
