Member Function Documentation

void osg::FrameBufferObject::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.

void osg::FrameBufferObject::apply ( State state,
BindTarget  target 
) const

Bind the FBO as either the read or draw target, or both.

int osg::FrameBufferObject::compare ( const StateAttribute sa) const [virtual]

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

Implements osg::StateAttribute.

GLenum osg::FrameBufferObject::convertBufferComponentToGLenum ( BufferComponent  attachment_point) const [protected]
static void osg::FrameBufferObject::deleteFrameBufferObject ( unsigned int  contextID,
GLuint  program 
) [static]

Mark internal FBO for deletion.

Deletion requests are queued until they can be executed in the proper GL context.

void osg::FrameBufferObject::dirtyAll ( ) [inline, protected]
static void osg::FrameBufferObject::discardDeletedFrameBufferObjects ( unsigned int  contextID) [static]

discard all the cached FBOs which need to be deleted in the OpenGL context related to contextID.

static void osg::FrameBufferObject::flushDeletedFrameBufferObjects ( unsigned int  contextID,
double  currentTime,
double &  availableTime 
) [static]

flush all the cached FBOs which need to be deleted in the OpenGL context related to contextID.

virtual void osg::FrameBufferObject::releaseGLObjects ( osg::State = 0) const [virtual]

If State is non-zero, this function releases any associated OpenGL objects for the specified graphics context.

Otherwise, releases OpenGL objexts for all graphics contexts.

Reimplemented from osg::StateAttribute.

virtual void osg::FrameBufferObject::resizeGLObjectBuffers ( unsigned int  maxSize) [virtual]

Resize any per context GLObject buffers to specified size.

Reimplemented from osg::StateAttribute.

void osg::FrameBufferObject::setAttachment ( BufferComponent  attachment_point,
const FrameBufferAttachment attachment 
)
void osg::FrameBufferObject::updateDrawBuffers ( ) [protected]
