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
