I am unable to migrate a call to Cesium.Shapes.computeCircleBoundary to get boundary points on a circle using the CircleOutlineGeometry (b29).

Objective: To get N distinct points R radians/D Degrees offset from each other, e.g 4 points on a circle boundary 90 degrees offset from each other. The same applies for points on an ellipse only the points might be at the semi-minor/major/ellipse boundaries.

Previously I would call;

Cesium.Shapes.computeCircleBoundary(Cesium.Ellipsoid.WGS84, circleCenterCartesian3.toString(), 250000.0, Math.PI / 2); to get points on the boundary of the circle.

like the following; (first 4 are relevant)

(-936293.5084711357, -3593004.369638257, 5174692.046762386),

(258063.45731426653, -4909440.063214418, 4049020.280361031),

(-1426866.9084858585, -5475568.28141778, 2923348.513959676),

(-2621223.874271261, -4159132.587841621, 4049020.280361031),

(-936293.5084711361, -3593004.369638257, 5174692.046762386),

Using the suggestion in the b29 Changes.md; I think I need to use CircleOutlineGeometry. However, doing that I am unable to get a 'nice' set of x,y,z positions as in the above example. In fact I don't really get useable positions at all as they seem to be duplicates of each other

So far I have;

var circle = new Cesium.CircleOutlineGeometry({

center : Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883),

radius : 100000.0,

granularity : Math.PI / 2

});

var geometry = Cesium.CircleOutlineGeometry.createGeometry(circle);

var float64ArrayPositions = geometry.attributes.position.values;

var positions = .slice.call(float64ArrayPositions);

1119258.861737524,-4760551.0964473635,4080785.815404867,

1312965.665401136,-4710807.606232919,4080785.8154048678

If I use Math.PI / 3 and so on, I just seem to get more useless points.

Also, as I flattening the positions values using slice, I no longer have an array of 3d positions which I can then use in say Polyline.positions or something but am unsure how to get those from a float64 array.

Any help would be appreciated.

Thanks.
