CZML Ellipsoid

• "ellipsoid": { "radii": { "cartesian": [x, y, z] }, "material": { "solidColor": { "color": { "rgba": [r,g,b,a] } } }, "fill": true|false, "outline": true|false, "outlineColor": { "rgba": [r,g,b,a] }, "slicePartitions": <integer>, "stackPartitions": <integer>, "show": true|false } — a three-dimensional analogue of an ellipse, centered on the entity's "position". "radii" is [X, Y, Z] in meters.
• A sphere is an ellipsoid with equal X, Y, and Z radii.
• "slicePartitions"/"stackPartitions" control the smoothness of the outline/tessellation for a wireframe-only (fill: false, outline: true) ellipsoid — raise both for a smoother outline.

Example: a blue ellipsoid, a red sphere, and a wireframe ellipsoid
