virtual void makVrv::DtOsgEmptySceneLogo::update ( DtOsgChannel &  osgChannel )

virtual

This method will check to see if a terrain is active and if not, an overlay will be shown. Once a terrain becomes active, the overlay will be removed.

static void makVrv::DtOsgEmptySceneLogo::setEnabled ( bool  enabled )

static

This global method will enable or disable the use of an empty scene overlay for all uses of this class. This is meant to be used from imGui to disable the overlay for debugging purposes.

static bool makVrv::DtOsgEmptySceneLogo::enabled ( )

static

This global method returns the enabled state of an empty scene overlay for all uses of this class.

virtual void makVrv::DtOsgEmptySceneLogo::createOverlay ( DtOsgChannel &  osgChannel )

protectedvirtual

Called by update() when the overlay needs created. Initializes the overlay and what is displayed on it.

virtual void makVrv::DtOsgEmptySceneLogo::destroyOverlay ( DtOsgChannel &  osgChannel )

protectedvirtual

Called by update() when the overlay needs destroyed. Destroys the overlay and what is displayed on it.

virtual void makVrv::DtOsgEmptySceneLogo::updateLayout ( int  x, int  y, int  w, int  h  )

protectedvirtual

Updates overlay elements to fit within the given vieport.

Parameters

x	- the viewport x position
y	- the viewport y position
w	- the viewport width
h	- the viewport height

virtual void makVrv::DtOsgEmptySceneLogo::slot_viewportChanged ( int  x, int  y, int  w, int  h  )

protectedvirtual

handle the signal for when the channel viewport changes

Parameters

x	- the viewport x position
y	- the viewport y position
w	- the viewport width
h	- the viewport height
