A model-like object that draws a 2D ellipse. This ellipse class inherits from DtWindowObject() which means it can be included in a parent/child relationship with other window objects, including surfaces, polygons, text, and lines. Vertices for this ellipse are relative to a fixed position, this is the position set for the center. Rotations are also relative to this position. If a position is not set, the default position is (0.0,0.0). If this object is a child of a surface, and that surface has a clip box set, this objects vertices will automatically be clipped in it's update method. If this object is a child of another object, the position set is relative to the parent.

virtual void makVrv::DtWindowEllipse::setCenter	(	double	x,
		double	y
	)

virtual

Set the center of the ellipse in normalized screen coordinates.

For example, setCenter(0.1, 0.5) sets the center to 10% horizontally from the left of the creen and 50% vertically from the bottom

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

virtual

Set the dimensions of the ellipse (the lengths of its axes) in normalizes screen coordinates.

For example, setDimensions(0.3, 0.5) sets the ellipse to 30% of the screen size horizontally and 50% vertically.

virtual void makVrv::DtWindowEllipse::setNumVertices ( int numVertices )

virtual

Set the number of vertices to use in approximating the ellipse; Default is 32.

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

virtual

Set the ellipse's visibility.

Reimplemented from makVrv::DtWindowObject.

virtual void makVrv::DtWindowEllipse::setStipplePattern ( unsigned int stipplePattern )

virtual

Set the stipple pattern.

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

virtual

Set the ellipse's color.

Reimplemented from makVrv::DtWindowObject.

virtual void makVrv::DtWindowEllipse::setFill ( bool fill )

virtual

Set the ellipse to filled or outlined.

virtual void makVrv::DtWindowEllipse::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.

Reimplemented from makVrv::DtWindowObject.

virtual void makVrv::DtWindowEllipse::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. This draws the same objects on ALL displays. If a user wishes to draw specific window object on a specific channel, use this method. This does not work for remote displays.

Reimplemented from makVrv::DtWindowObject.

virtual void makVrv::DtWindowEllipse::setInnerDimensions	(	double	xLength,
		double	yLength
	)

virtual

Set the inner dimensions of this ellipse, if this is set the ellipse shall be rendered hollow.

virtual void makVrv::DtWindowEllipse::setStartEndAngles	(	double	startAngle,
		double	endAngle
	)

virtual

Allows for drawing of subsections of an ellipse.

virtual void makVrv::DtWindowEllipse::setLineWidth ( float lineWidth )

virtual

Set line width if this ellipse is outlined.

virtual void makVrv::DtWindowEllipse::update ( )

protectedvirtual

Called on signal_postUpdate; time to update render data.

virtual void makVrv::DtWindowEllipse::needsUpdate ( )

protectedvirtual

Called by all mutators to set up a postUpdate signal if not already connected.

Reimplemented from makVrv::DtWindowObject.
