gov.nasa.worldwindx.examples.tutorial.Cube.OrderedCube

All Implemented Interfaces:

OrderedRenderable, Renderable

Enclosing class:

Cube

protected class Cube.OrderedCube
extends Object
implements OrderedRenderable

This class holds the Cube's Cartesian coordinates. An instance of it is added to the scene controller's ordered renderable queue during picking and rendering.

Method Detail

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.

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
