This class updates vertices for each ellipse added via addellipse. They are stored in a vector of EllipseStructs which contain the verts and stipple pattern. You can update the ellipses after they have been added without deleting them using updateellipse. This means that they do not flash on screen. Please call setEllipseCount before adding ellipses. updateEllipse will adjust the number of DtFilledPolygons this class has to match myEllipseCount. If the ellipse is outlined a DtFilledPolygon is not used, a vertor of DtSegementedLines is instead.

Member Function Documentation

virtual void makVrv::DtOsgWindowEllipseGroupInstance::setEllipseCount ( unsigned int count )

virtual

Set the number of ellipses that this group will have Should be set before addEllipse is called.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::addEllipse	(	unsigned int	stipplePattern,
		bool	fill,
		float	lineWidth,
		float	centerX,
		float	centerY,
		float	radius,
		float	innerRadius,
		float	startAngle,
		float	endAngle
	)

virtual

Add an ellipse to the specified in params Angles are in radians. Calls createEllipseStruct.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::updateEllipse	(	unsigned int	index,
		unsigned int	stipplePattern,
		bool	fill,
		float	lineWidth,
		float	centerX,
		float	centerY,
		float	radius,
		float	innerRadius,
		float	startAngle,
		float	endAngle
	)

virtual

Update the ellipse at in param index with in parma specs. The reason index is passed in is because we need to know which ellipse to update. You cannot just delete all the pointers and recreate once all the updateEllipse calls arrive ( indexNumber = myEllipseCount ), because the ellipses will flash on screen!!

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

virtual

Set all of the ellipses to visible or invisible.

Reimplemented from makVrv::DtOsgWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::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.

Reimplemented from makVrv::DtOsgWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::updateVertices ( )

protectedvirtual

Generate the vertices of the graphic polygon that approximates the ellipse Loops through myEllipses updating vertices on either the filled polygons or lines. Called by DtOsgWindowEllipseInstance::update()

Reimplemented from makVrv::DtOsgWindowEllipseInstance.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::updateFilledPolygon	(	DtFilledPolygon *	poly,
		Ellipse	ellipseInfo
	)

protectedvirtual

Update the in param polygon to the in param ellipseInfo.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::updateLineSegments	(	std::vector< DtSegmentedLine * > &	vec,
		Ellipse	ellipseInfo
	)

protectedvirtual

Update the in param vector of lines to the in param ellipseInfo.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::deleteAllEllipses ( )

protectedvirtual

Delete all the pointers and structs in myEllipses.

DtFilledPolygon* makVrv::DtOsgWindowEllipseGroupInstance::createFilledPolygon ( )

protected

Create a DtFilledPolygon.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::createLinesVector	(	unsigned int	lineCount,
		std::vector< DtSegmentedLine * > &	vec
	)

protectedvirtual

Create a vector of DtSegmentedLines.

virtual void makVrv::DtOsgWindowEllipseGroupInstance::createEllipseStruct ( Ellipse ellipse )

protectedvirtual

Create an ellipse struct from the passed in ellipse Creates a DtFilledPolygon or a vector of segmented lines depending on the fill. Pushes the struct into myEllipses.
