animating sphere size and position i get a hole on north pole

hi i send you my code samples and the image

if i have no animation the spheres have no holes

var point1 = new Cesium.SampledPositionProperty();

point1.addSample(startdelay, surfacePosition);

point1.addSample(stop, offsetheightPosition);

var radius = new Cesium.SampledProperty(Cesium.Cartesian3);

radius.addSample(startdelay, new Cesium.Cartesian3(0, 0, 0));

radius.addSample(stop, new Cesium.Cartesian3(sphereRadius, sphereRadius,sphereRadius));


id: seriesName + ’ Friends ’ + i.toString(),

position: point1,

ellipsoid: {

radii: radius,

outline: false,

fill: true,

material: sphereColor


Ca you help me ?


That definitely seems like a bug. I’ve submitted an issue here:
