KBE3D / KBCore / Cesium / MapProjection

类: MapProjection

Defines how geodetic ellipsoid coordinates (Cartographic) project to a flat map like Cesium's 2D and Columbus View modes.

属性

ellipsoid

readonly ellipsoid: Ellipsoid

Gets the Ellipsoid.

方法

project()

project(cartographic: Cartographic, result?: Cartesian3): Cartesian3

Projects Cartographic coordinates, in radians, to projection-specific map coordinates, in meters.

参数

cartographic

Cartographic

The coordinates to project.

result?

Cartesian3

An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned.

返回

Cartesian3

The projected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.

---

unproject()

unproject(cartesian: Cartesian3, result?: Cartographic): Cartographic

Unprojects projection-specific map Cartesian3 coordinates, in meters, to Cartographic coordinates, in radians.

参数

cartesian

Cartesian3

The Cartesian position to unproject with height (z) in meters.

result?

Cartographic

An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned.

返回

Cartographic

The unprojected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.
