OSG Implementation of DtWindowEllipseInstance. Uses vrvGraphics to implement a 2D ellipse. Creates either a DtFilledPolygon or a vector of DtSegmentedLines. The vector of lines is so that the outlined ellipse can be clipped. A filled Ellipse using a DtFilledPolygon can be drawn using a start and end angle in rads, inner and outer dimensions. An outlined ellipse can be drawn with a start and end angle in rads, and a line width.

virtual

Set the number of vertices in the ellipse.

Implements makVrv::DtWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseInstance::setDimensions	(	double	xLength,
		double	yLength
	)

virtual

Set the lengths of the ellipse's axes in normalized screen coordinates.

Implements makVrv::DtWindowEllipseInstance.

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

virtual

Set the ellipse's color.

Implements makVrv::DtWindowEllipseInstance.

virtual bool makVrv::DtOsgWindowEllipseInstance::visible ( )

virtual

Return visibility status.

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

virtual

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

Implements makVrv::DtWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseInstance::update ( )

virtual

Called on signal_postUpdate; time to update render data.

Implements makVrv::DtWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseInstance::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::DtWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseInstance::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::DtWindowEllipseInstance.

Reimplemented in makVrv::DtOsgWindowEllipseGroupInstance.

virtual void makVrv::DtOsgWindowEllipseInstance::setInnerDimensions	(	double	xLength,
