virtual void makVrv::DtOsgWindowTriangleFanInstance::setVisible ( bool isVisible )

virtual

Set the TriangleFan visible or invisible.

Implements makVrv::DtSetVisibilityInterface.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setFillPattern ( unsigned int fillPattern )

virtual

Set the TriangleFan's fill pattern.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setNumVertices ( unsigned int numVertices )

virtual

Set the number of vertices in the TriangleFan.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setVertex	(	int	i,
		double	x,
		double	y
	)

virtual

Set one of the TriangleFan's vertices.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setColor	(	float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set the TriangleFan's color.

Implements makVrv::DtWindowTriangleFanInstance.

virtual bool makVrv::DtOsgWindowTriangleFanInstance::visible ( ) const

virtual

Get the TriangleFan's visibility status.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setTransform ( DtMatrix3< double > transform )

virtual

Sets the line's transform matrix, used to update the position and clockwise rotation of the vertices.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::update ( )

virtual

Called on signal_postUpdate; time to update render data.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setGroup ( int groupId )

virtual

Set this object's group ID for z order. The higher the Z order the "closer" the element will be drawn to the eye point.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setChannelOverlay	(	const std::string &	displayName,
		const std::string &	windowName,
		const std::string &	channelName
	)

overridevirtual

By default window objects are placed on the RemoteDisplayWorldOverlay, which is rendered on all channels that have the "showRemoteGraphics" channel keyword. If a user wishes to draw a specific window object on a specific channel, use this method. This does not work for remote displays.

Implements makVrv::DtWindowTriangleFanInstance.

void makVrv::DtOsgWindowTriangleFanInstance::createTriangleFan ( )

Create myTriangleFan according to current state Called from the constructor, so this can't be virtual.

virtual void makVrv::DtOsgWindowTriangleFanInstance::updateGeometry ( )

protectedvirtual

Update the graphic TriangleFan's vertices according to the current state.

virtual void makVrv::DtOsgWindowTriangleFanInstance::setClipBox	(	DtVector2< double >	bottomLeftLocation,
		DtVector2< double >	topRightLocation
	)

protectedvirtual

Set this objects clip box bounds.

Implements makVrv::DtWindowTriangleFanInstance.

virtual void makVrv::DtOsgWindowTriangleFanInstance::slot_channelToBeDestroyed	(	DtChannelManager *	,
		DtChannel *
	)

protectedvirtual

Destroy the triangle fan when the channel its being rendered on is going to be destroyed.
