ReferenceFrame.FIXED
|
optional The reference frame in which the position is defined. |
Members
-
definitionChanged :Event
-
Gets the event that is raised whenever the definition of this property changes. The definition is considered to have changed if a call to getValue would return a different result for the same time.
-
interpolationAlgorithm :InterpolationAlgorithm
-
Gets the interpolation algorithm to use when retrieving a value.
-
Default Value:
LinearApproximation
-
interpolationDegree :Object
-
Gets the degree of interpolation to perform when retrieving a value.
-
Default Value:
1
-
isConstant :Boolean
-
Gets a value indicating if this property is constant. A property is considered constant if getValue always returns the same result for the current definition.
-
referenceFrame :ReferenceFrame
-
Gets the reference frame in which the position is defined.
-
Default Value:
ReferenceFrame.FIXED;
Methods
-
addSample(time, value)
-
Adds a new sample
Name Type Description time
JulianDate The sample time. value
Cartesian3 The value at the provided time. -
addSamples(times, values)
-
Adds an array of samples
Name Type Description times
JulianDate[] An array of JulianDate instances where each index is a sample time. values
Cartesian3[] The array of Cartesian3 instances, where each value corresponds to the provided times index. Throws:
-
DeveloperError : times and values must be the same length..
-
-
addSamplesPackedArray(packedSamples, epoch)
-
Adds samples as a single packed array where each new sample is represented as a date, followed by the packed representation of the corresponding value.
Name Type Description packedSamples
Number[] The array of packed samples. epoch
JulianDate optional If any of the dates in packedSamples are numbers, they are considered an offset from this epoch, in seconds. -
equals(other) → Boolean
-
Compares this property to the provided property and returns
true
if they are equal,false
otherwise.Name Type Description other
Property optional The other property. Returns:
true
if left and right are equal,false
otherwise. -
getValue(time, result) → Cartesian3
-
Gets the value of the property at the provided time.
Name Type Description time
JulianDate The time for which to retrieve the value. result
Cartesian3 optional The object to store the value into, if omitted, a new instance is created and returned. Returns:
The modified result parameter or a new instance if the result parameter was not supplied. -
getValueInReferenceFrame(time, referenceFrame, result) → Cartesian3
-
Gets the value of the property at the provided time and in the provided reference frame.
Name Type Description time
JulianDate The time for which to retrieve the value. referenceFrame
ReferenceFrame The desired referenceFrame of the result. result
Cartesian3 optional The object to store the value into, if omitted, a new instance is created and returned. Returns:
The modified result parameter or a new instance if the result parameter was not supplied. -
setInterpolationOptions(options)
-
Sets the algorithm and degree to use when interpolating a position.
Name Type Description options
Object The options Name Type Description interpolationAlgorithm
InterpolationAlgorithm optional The new interpolation algorithm. If undefined, the existing property will be unchanged. interpolationDegree
Number optional The new interpolation degree. If undefined, the existing property will be unchanged.
