Class AxesWidget

java.lang.Object

vona.j3d.Widget

vona.j3d.AxesWidget

public class AxesWidget
extends Widget

A widget with an axes triad.

trackWidgetLength(float...) may be called to enable Widget.widgetLength tracking, which causes the axes radius to track Widget.widgetLength*trackRadiusFactor.

Vertex array is 3 C3_V lines.
