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

pure 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

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure 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.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set the ellipse's fill pattern.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set the number of vertices to use approximating the ellipse.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set the ellipse's color.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set the ellipse filled or outlined.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

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

Implemented in makVrv::DtOsgWindowEllipseInstance.

virtual void makVrv::DtWindowEllipseInstance::update ( )

pure virtual

Called on signal_postUpdate; time to update render data.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set this objects clip box bounds.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure 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.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

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.

Implemented in makVrv::DtOsgWindowEllipseInstance, and makVrv::DtOsgWindowEllipseGroupInstance.

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

pure virtual

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

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Allows for drawing of subsections of an ellipse.

Implemented in makVrv::DtOsgWindowEllipseInstance.

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

pure virtual

Set line width if this ellipse is outlined.

Implemented in makVrv::DtOsgWindowEllipseInstance.
