Member Function Documentation

virtual void osg::BufferIndexBinding::apply ( State & ) const

virtual

apply the OpenGL state attributes.

The render info for the current OpenGL context is passed in to allow the StateAttribute to obtain details on the the current context and state.

Reimplemented from osg::StateAttribute.

BufferObject* osg::BufferIndexBinding::getBufferObject ( ) const

inline

Get the buffer object to be bound.

GLuint osg::BufferIndexBinding::getIndex ( ) const

inline

Get the index target.

virtual unsigned osg::BufferIndexBinding::getMember ( ) const

inlinevirtual

Return the member identifier within the attribute's class type.

Used for light number/clip plane number etc.

Reimplemented from osg::StateAttribute.

GLintptr osg::BufferIndexBinding::getOffset ( ) const

inline

GLsizeiptr osg::BufferIndexBinding::getSize ( ) const

inline

GLenum osg::BufferIndexBinding::getTarget ( ) const

inline

void osg::BufferIndexBinding::setBufferObject ( BufferObject * bo )

inline

Set the buffer object that will be bound to the index target.

void osg::BufferIndexBinding::setOffset ( GLintptr offset )

inline

Set the starting offset into the buffer object for data for the indexed target.

Note: the required alignment on the offset may be quite large (e.g., 256 bytes on NVidia 8600M). This should be checked with glGetIntegerv(GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT...).

void osg::BufferIndexBinding::setSize ( GLsizeiptr size )

inline

Set the size of data for the indexed target.
