Detailed Description

A model-like object that draws a 2D polygon on screen.

This polygon class inherits from DtWindowObject() which means it can be included in a parent/child relationship with other window objects, including surfaces, lines, text, and ellipses. Vertices for this polygon are relative to a fixed position, this is the position set in the base class. 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. createInstance() must be called first for the other methods in this class to work. Note that this polygon does not support concave shapes where a vertex is further into the center of the polygon that the center calculated from all the vertices. The triangles in this polygon each share a vertex with the center of the polygon. A DtTriangleFan fully supports concave shapes.

Member Function Documentation

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

virtual

Set the ith vertex of the polygon.

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

virtual

Set the number of vertices in the polygon.

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

virtual

Set the polygon visible or invisible.

Reimplemented from makVrv::DtWindowObject.

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

virtual

Set the stipple pattern.

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

virtual

Set the polygon's color.

Reimplemented from makVrv::DtWindowObject.

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

virtual

Set the polygon to filled or outlined.

virtual void makVrv::DtWindowPolygon::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::DtWindowPolygon::setChannelOverlay	(	std::string	displayName,
		std::string	windowName,
		std::string	channelName
	)

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.

Reimplemented from makVrv::DtWindowObject.

virtual void makVrv::DtWindowPolygon::update ( )

protectedvirtual

Called on signal_postUpdate; time to update render data.

virtual void makVrv::DtWindowPolygon::needsUpdate ( )

protectedvirtual

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

Reimplemented from makVrv::DtWindowObject.
