Constructor & Destructor Documentation

makVrv::DtGlStudioDrawable::DtGlStudioDrawable

(

)

constructor

makVrv::DtGlStudioDrawable::DtGlStudioDrawable

(

disti::ComponentBase *

component

)

CTOR which takes a disti component. For loading user-instantiated (statically linked) component object.

makVrv::DtGlStudioDrawable::DtGlStudioDrawable	(	const DtGlStudioDrawable &	other,
		const osg::CopyOp &	copyop = osg::CopyOp::SHALLOW_COPY
	)

Copy constructor using CopyOp to manage deep vs shallow copy. For loading from a live component DLL.

virtual makVrv::DtGlStudioDrawable::~DtGlStudioDrawable ( )

virtual

DTOR.

Member Function Documentation

virtual osg::Object* makVrv::DtGlStudioDrawable::cloneType ( ) const

virtual

Required osg::Object class methods.

virtual osg::Object* makVrv::DtGlStudioDrawable::clone ( const osg::CopyOp &  copyop ) const

virtual

virtual bool makVrv::DtGlStudioDrawable::isSameKindAs ( const osg::Object *  obj ) const

virtual

virtual const char* makVrv::DtGlStudioDrawable::libraryName ( ) const

virtual

virtual const char* makVrv::DtGlStudioDrawable::className ( ) const

virtual

virtual bool makVrv::DtGlStudioDrawable::loadLiveComponent ( const std::string &  fileName, const std::string &  className  )

virtual

Loads a live component from a GL Studio shared library.

virtual void makVrv::DtGlStudioDrawable::destroyComponent ( )

virtual

Frees the memory for the component.

virtual void makVrv::DtGlStudioDrawable::setComponent ( disti::ComponentBase *  comp )

virtual

Replace the currently loaded component with the given component instance. The node takes ownership of the object.

virtual disti::ComponentBase* makVrv::DtGlStudioDrawable::component ( )

virtual

Get access to the component pointer to allow for calling component-specific methods.

virtual bool makVrv::DtGlStudioDrawable::handleMouseInput ( const DtMouseEvent &  ea )

virtual

handle mouse events

virtual osg::BoundingBox makVrv::DtGlStudioDrawable::computeBoundingBox ( ) const

virtual

Computes the bounding box if needed.

virtual bool makVrv::DtGlStudioDrawable::supports ( osg::PrimitiveFunctor &  ) const

virtual

OSG required function.

virtual void makVrv::DtGlStudioDrawable::accept ( osg::PrimitiveFunctor &  functor ) const

virtual

The PrimitiveFunctor is used for OpenSceneGraph picking The Drawable object should tell the PrimitiveFunctor about it's geometry. Since we are unable to get the detailed geometry here we use the bounding box geometry for osg picking. Detailed picking of component geometry is done within HandleInput.

virtual void makVrv::DtGlStudioDrawable::update ( unsigned int  frameNumber )

virtual

The update function is called each frame. This is where we call Calculate() on the component.

virtual bool makVrv::DtGlStudioDrawable::cull ( osg::NodeVisitor *  visitor, osg::Drawable *  drawable, osg::State *  state = NULL  ) const

virtual

virtual void makVrv::DtGlStudioDrawable::drawImplementation ( osg::RenderInfo &  state ) const

virtual

virtual void makVrv::DtGlStudioDrawable::setProperty ( const std::string &  prop, const std::string &  val  )

virtual

virtual void makVrv::DtGlStudioDrawable::setDe ( DtDe *  de )

virtual

virtual void makVrv::DtGlStudioDrawable::setCockpitObject ( DtOsgGlStudioCockpit *  cockpitObject )

virtual

virtual void makVrv::DtGlStudioDrawable::releaseGLObjects ( osg::State *  state = 0 ) const

virtual

virtual void makVrv::DtGlStudioDrawable::dirtyRenderObjects ( )

virtual

used by the cockpit to let the drawable know that something changed with the rendering so rebuild the rtt shader and drawable.

virtual void makVrv::DtGlStudioDrawable::initQuadRendering ( const osg::Camera *  camera ) const

protectedvirtual

initialize the geometry to render the RTT texture on top of the current framebuffer

virtual void makVrv::DtGlStudioDrawable::deinitQuadRendering ( ) const

protectedvirtual

tear down the geometry used to render the RTT texture

virtual void makVrv::DtGlStudioDrawable::initRTT ( const osg::Camera *  camera ) const

protectedvirtual

setup the rtt for the texture that is used when HDR is turned on

virtual void makVrv::DtGlStudioDrawable::deinitRTT ( ) const

protectedvirtual

tear down the rtt for the HDR cockpit textue

virtual void makVrv::DtGlStudioDrawable::slot_reloadShaders ( )

protectedvirtual

slot for reload shaders signal so the cockpit RTT shader can be reloaded

virtual float makVrv::DtGlStudioDrawable::calculateHdrOutputScale ( const osg::Camera *  camera ) const

protectedvirtual

get the hdr output scale to set up

virtual bool makVrv::DtGlStudioDrawable::calculateSkyEnabled ( const osg::Camera *  camera ) const

protectedvirtual

get the sky enabled bool to set up
