Related to #6631 [`DynamicEllipsoidGeometryUpdater`](https://github.com/AnalyticalGraphicsInc/cesium/blob/master/Source/DataSources/EllipsoidGeometryUpdater.js#L247) was optimized so that it only recreates the `EllipsoidGeometry` when certain properties that require a recreation change. `DynamicBoxGeometryUpdater` could be optimized similarly. @mc-allen if you open...
