Field Detail

altitudeMode

protected int altitudeMode

Indicates how this balloon's altitude is interpreted. One of WorldWind.ABSOLUTE, WorldWind.RELATIVE_TO_GROUND, or WorldWind.CLAMP_TO_GROUND. If the altitude mode is 0 or an unrecognized code, this balloon assumes an altitude mode of WorldWind.ABSOLUTE. Initially 0.

position

protected Position position

Indicates this balloon's geographic position. The position's altitude is interpreted relative to this balloon's altitudeMode. Initialized to a non-null value at construction.

Constructor Detail

GlobeBrowserBalloon

public GlobeBrowserBalloon(java.lang.String text,
                           Position position)

Constructs a new GlobeBrowserBalloon with the specified text content and position.

Parameters:

text - the balloon's initial text content.

position - the balloon's initial position.

Throws:

java.lang.IllegalArgumentException - if either text or position are null.

Method Detail

computeBalloonPoints

protected void computeBalloonPoints(DrawContext dc,
                                    AbstractBrowserBalloon.OrderedBrowserBalloon obb)

Computes and stores this balloon's model and screen coordinates. This assigns balloon coordinate properties as follows:

• placePoint - this balloon's model-coordinate point, according to its altitude mode.
• screenPlacePoint - screen-space projection of the placePoint.
• screenOffset - the balloon frame's screen-coordinate offset from this balloon's screenPlacePoint.
• screenRect - the balloon frame's screen-coordinate rectangle.
• screenExtent - this balloon's screen-coordinate bounding rectangle.
• screenPickExtent - this balloon's screen-coordinate bounding rectangle, including area covered by the balloon's pickable outline.
• webViewRect - the WebView's screen-coordinate content frame.
• eyeDistance - always 0.

Specified by:

computeBalloonPoints in class AbstractBrowserBalloon

Parameters:

dc - the current draw context.

createOrderedRenderable

protected AbstractBrowserBalloon.OrderedBrowserBalloon createOrderedRenderable()

Specified by:

createOrderedRenderable in class AbstractBrowserBalloon

createPickedObject

protected PickedObject createPickedObject(DrawContext dc,
                                          java.awt.Color pickColor)

Overridden to use this balloon's position as the picked object's position.

Overrides:

createPickedObject in class AbstractBrowserBalloon

getAltitudeMode

public int getAltitudeMode()

Returns the balloon's altitude mode. See GlobeBalloon.setAltitudeMode(int) for a description of the modes.

Specified by:

getAltitudeMode in interface GlobeBalloon

Returns:

the balloon's altitude mode.

getPosition

public Position getPosition()

Get the position of the balloon.

Specified by:

getPosition in interface GlobeBalloon

Returns:

The position of the balloon.

intersectsFrustum

protected boolean intersectsFrustum(DrawContext dc,
                                    AbstractBrowserBalloon.OrderedBrowserBalloon obb)

Determines whether the balloon intersects the view frustum.

Overridden to return false if the balloon's position is either behind the View's near clipping plane or in front of the View's far clipping plane. Otherwise this delegates to the super class' behavior.

Overrides:

intersectsFrustum in class AbstractBrowserBalloon

Parameters:

dc - the current draw context.

Returns:

true If the balloon intersects the frustum, otherwise false.

setAltitudeMode

public void setAltitudeMode(int altitudeMode)

Specifies the balloon's altitude mode. Recognized modes are:

• @link WorldWind#CLAMP_TO_GROUND} -- the balloon is placed on the terrain at the latitude and longitude of its position.
• @link WorldWind#RELATIVE_TO_GROUND} -- the balloon is placed above the terrain at the latitude and longitude of its position and the distance specified by its elevation.
• WorldWind.ABSOLUTE -- the balloon is placed at its specified position.

Specified by:

setAltitudeMode in interface GlobeBalloon

Parameters:

altitudeMode - the altitude mode

setPosition

public void setPosition(Position position)

Set the balloon to a position on the globe.

Specified by:

setPosition in interface GlobeBalloon

Parameters:

position - New position for the balloon.

setupDepthTest

protected void setupDepthTest(DrawContext dc,
                              AbstractBrowserBalloon.OrderedBrowserBalloon obb)

Specified by:

setupDepthTest in class AbstractBrowserBalloon
