public class CircleWidget extends JOGLEdgedFacetedWidget
A circle.
The face geometry is tessellated into azimuth wedges, with defined normals. The edge geometry is composed of the perimeter circle.
The radius is mutable, and the circle is centered at the origin of the
local coordinate frame, with outward normal along the positive Z axis. It
may be further positioned e.g. by manipulating Widget.rx.
trackWidgetLength(float...) may be called to enable Widget.widgetLength
tracking, which causes the radius length to track Widget.widgetLength*trackRadiusFactor.
Face vertex array is one fan in ccw order from (r, 0, 0).
Edge vertex array is one line strip in ccw order from (r, 0, 0).
