new CompositeProperty()
A
Property which is defined by a TimeIntervalCollection, where the
data property of each TimeInterval is another Property instance which is
evaluated at the provided time.
Example:
var constantProperty = ...;
var sampledProperty = ...;
//Create a composite property from two previously defined properties
//where the property is valid on August 1st, 2012 and uses a constant
//property for the first half of the day and a sampled property for the
//remaining half.
var composite = new Cesium.CompositeProperty();
composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601('2012-08-01T00:00:00.00Z/2012-08-01T12:00:00.00Z', true, true, constantProperty));
composite.intervals.addInterval(Cesium.TimeInterval.fromIso8601('2012-08-01T12:00:00.00Z/2012-08-02T00:00:00.00Z', false, false, sampledProperty));See:
