KBE3D / KBCore / Cesium / CompositePositionProperty

类: CompositePositionProperty

A CompositeProperty which is also a PositionProperty.

参数

The reference frame in which the position is defined.

属性

isConstant

readonly 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.

---

definitionChanged

readonly definitionChanged: Event

Gets the event that is raised whenever the definition of this property changes. The definition is changed whenever setValue is called with data different than the current value.

---

intervals

intervals: TimeIntervalCollection

Gets the interval collection.

---

referenceFrame

referenceFrame: ReferenceFrame

Gets or sets the reference frame which this position presents itself as. Each PositionProperty making up this object has it's own reference frame, so this property merely exposes a "preferred" reference frame for clients to use.

方法

getValue()

getValue(time?: JulianDate, result?: Cartesian3): Cartesian3 | undefined

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?

Cartesian3

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

返回

Cartesian3 | undefined

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

---

getValueInReferenceFrame()

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

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?

Cartesian3

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

返回

Cartesian3 | undefined

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

---

equals()

equals(other?: Property): boolean

Compares this property to the provided property and returns <code>true</code> if they are equal, <code>false</code> otherwise.

参数

other?

Property

The other property.

返回

boolean

true if left and right are equal, false otherwise.
