Geographic position in cartesian coordinates.

rotation

protected Angle rotation

Rotation applied to the label. This is computed each frame based on the orientation position.

screenExtent

protected Rectangle screenExtent

Extent of the label on the screen.

screenPlacePoint

protected Vec4 screenPlacePoint

Location of the place point projected onto the screen.

screenPoint

protected Point screenPoint

Location of the upper left corner of the text measured from the lower left corner of the viewport. This point in OGL coordinates.

getDistanceFromEye

public double getDistanceFromEye()

Description copied from interface: OrderedRenderable

Returns the ordered renderable's distance from the current view's eye point. Intended to be used only to sort a list of ordered renderables according to eye distance, and only during frame generation when a view is active.

Specified by:

getDistanceFromEye in interface OrderedRenderable

Returns:

the distance of the ordered renderable from the current view's eye point.

getFont

protected Font getFont()

getPickLayer

public Layer getPickLayer()

isDrawInterior

protected boolean isDrawInterior()

isEnableBatchPicking

public boolean isEnableBatchPicking()

isEnableBatchRendering

public boolean isEnableBatchRendering()

pick

public void pick(DrawContext dc,
                 Point pickPoint)

Description copied from interface: OrderedRenderable

Executes a pick of the ordered renderable.

Specified by:

pick in interface OrderedRenderable

Parameters:

dc - the current draw context.

pickPoint - the pick point.

render

public void render(DrawContext dc)

Description copied from interface: Renderable

Causes this Renderable to render itself using the provided draw context.

Specified by:

render in interface Renderable

Parameters:

dc - the DrawContext to be used
