| Julian date ,Position in the x-axis ,Position in the y_axis,Position in the z-axis|

Properties

dates - List<JulianDate> : The dates of each position in the Julian calendar.

positions - List<Cartesian> : The list of positions of the object in time, the list must be of the same size of dates.

cesiumInterpolationAlgorithm - CesiumInterpolationAlgorithm : The interpolation algorithm to use when interpolating. Is can take the values :

• LAGRANGE
• LINEAR
• HERMITE
• default : LAGRANGE

interpolationDegree - int : The degree of interpolation while interpolating, default : 5.

referenceFrame - String : Defines which frame to use, can take two different values :

• "FIXED" : For a non-rotating referential frame.
• "INERTIAL" : For a rotating inertial reference frame.
• default : "INERTIAL" .

Build

The time position object can be build with :

• A list of cartesian object, a list of double representing number of seconds since the start of the simulation

TimePosition timePosition = new TimePosition(cartesians, timeList);
