referenceFrame

referenceFrame: ReferenceFrame

Gets the reference frame in which the position is defined.

方法

getValue()

getValue(time?: JulianDate, result?: any): any

Gets the value of the property at the provided time in the fixed frame.

参数

time?

JulianDate

The time for which to retrieve the value. If omitted, the current system time is used.

result?

any

The object to store the value into, if omitted, a new instance is created and returned.

any

The modified result parameter or a new instance if the result parameter was not supplied.

---

setValue()

setValue(value: Cartesian3, referenceFrame?: ReferenceFrame): void

Sets the value of the property.

参数

value

Cartesian3

The property value.

referenceFrame?

ReferenceFrame

The reference frame in which the position is defined.

返回

void

---

getValueInReferenceFrame()

getValueInReferenceFrame(time: JulianDate, referenceFrame: ReferenceFrame, result?: Cartesian3): Cartesian3

Gets the value of the property at the provided time and in the provided reference frame.

参数

time

JulianDate

The time for which to retrieve the value.

referenceFrame

ReferenceFrame

The desired referenceFrame of the result.

result?
