Constructor Detail

ClusteredView

public ClusteredView(ClusterGeometry clGeom,
                     int origin,
                     int viewCols,
                     int viewRows,
                     List<Camera> cameras)

Constructs a new ClusteredView.

Parameters:

clGeom - cluster geometry

origin - origin (bottom-left) block number

viewRows - number of rows in the view (viewRows <= nbRows)

viewCols - number of columns in the view (viewCols <= nbCols)

cameras - a list of cameras observed by this ClusteredView.

Method Detail

getObjId

public ObjId getObjId()

Description copied from class: DefaultIdentifiable

Returns the ObjId of this Identifiable.

Specified by:

getObjId in interface Identifiable

Overrides:

getObjId in class DefaultIdentifiable

setBackgroundColor

public void setBackgroundColor(Color color)

Sets the background color for this ClusteredView.

Parameters:

color - new background color

getBackgroundColor

public Color getBackgroundColor()

Gets the background color.

Returns:

the current background color

getSize

public Dimension getSize()

Returns the size of this ClusteredView, in pixels. The width of this view is equal to blockWidth*viewCols The height of this view is equal to blockHeight*viewRows

spaceToViewCoords

public Point spaceToViewCoords(Camera cam,
                               double xPos,
                               double yPos)

Parameters:

xPos - point x-coordinate, in VirtualSpace coords

yPos - point y-coordinate, in VirtualSpace coords

Returns:

the coordinates of a point at (xPos, yPos), in view coordinates (ie (0,0) top-left, x increases to the right, y increases downwards)

Throws:

IllegalArgumentException - If cam does not belong to this ClusteredView

viewToSpaceCoords

public Point2D.Double viewToSpaceCoords(Camera cam,
                                        int xPos,
                                        int yPos)

Converts the coordinates of a point given in ClusteredView coordinates into VirtualSpace coordinates.

Parameters:

xPos - point x-coodinate, in View coords

yPos - point y-coordinate, in View coords

Throws:

IllegalArgumentException - If cam does not belong to this ClusteredView

centerOnRegion

public Location centerOnRegion(Camera cam,
                               double x1,
                               double y1,
                               double x2,
                               double y2)

Parameters:
