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