---

toCartesian()

static toCartesian(cartographic: Cartographic, ellipsoid?: Ellipsoid, result?: Cartesian3): Cartesian3

Creates a new Cartesian3 instance from a Cartographic input. The values in the inputted object should be in radians.

Input to be converted into a Cartesian3 output.

ellipsoid?

Ellipsoid

The ellipsoid on which the position lies.

result?

Cartesian3

The object onto which to store the result.

返回

Cartesian3

The position

---

clone()

static clone(cartographic: Cartographic, result?: Cartographic): Cartographic

Duplicates a Cartographic instance.

参数

cartographic

Cartographic

The cartographic to duplicate.

result?

Cartographic

The object onto which to store the result.

返回

Cartographic

The modified result parameter or a new Cartographic instance if one was not provided. (Returns undefined if cartographic is undefined)

---

参数

left?

Cartographic

The first cartographic.

right?

Cartographic

The second cartographic.

epsilon?

number

The epsilon to use for equality testing.

返回

boolean

true if left and right are within the provided epsilon, false otherwise.

---

clone()

clone(result?: Cartographic): Cartographic

The object onto which to store the result.

返回

Cartographic

The modified result parameter or a new Cartographic instance if one was not provided.

---

equals()

equals(right?: Cartographic): boolean

Compares the provided against this cartographic componentwise and returns <code>true</code> if they are equal, <code>false</code> otherwise.

参数

right?
