Detailed Description

Encapsulate binding buffer objects to index targets. This specifically supports the uniform buffer and transform feedback targets.

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.
