KBE3D / KBCore / Cesium / GroundPolylineGeometry

类: GroundPolylineGeometry

A description of a polyline on terrain or 3D Tiles. Only to be used with GroundPolylinePrimitive.

示例

const positions = Cesium.Cartesian3.fromDegreesArray([
  -112.1340164450331, 36.05494287836128,
  -112.08821010582645, 36.097804071380715,
  -112.13296079730024, 36.168769146801104
]);

const geometry = new Cesium.GroundPolylineGeometry({
  positions : positions
});

参数

Options with the following properties:

参数

An array of Cartesian3 defining the polyline's points. Heights above the ellipsoid will be ignored.

参数

The screen space width in pixels.

参数

The distance interval in meters used for interpolating options.points. Defaults to 9999.0 meters. Zero indicates no interpolation.

参数

Whether during geometry creation a line segment will be added between the last and first line positions to make this Polyline a loop.

参数

The type of line the polyline segments must follow. Valid options are ArcType.GEODESIC and ArcType.RHUMB.

属性

width

width: number

The screen space width in pixels.

---

granularity

granularity: boolean

The distance interval used for interpolating options.points. Zero indicates no interpolation. Default of 9999.0 allows centimeter accuracy with 32 bit floating point.

---

loop

loop: boolean

Whether during geometry creation a line segment will be added between the last and first line positions to make this Polyline a loop. If the geometry has two positions this parameter will be ignored.

---

arcType

arcType: ArcType

The type of path the polyline must follow. Valid options are ArcType.GEODESIC and ArcType.RHUMB.

方法

pack()

static pack(value: PolygonGeometry, array: number[], startingIndex?: number): number[]

Stores the provided instance into the provided array.

参数

value

PolygonGeometry

The value to pack.

array

number[]

The array to pack into.

startingIndex?

number

The index into the array at which to start packing the elements.

返回

number[]

The array that was packed into

---

unpack()

static unpack(array: number[], startingIndex?: number, result?: PolygonGeometry): void

Retrieves an instance from a packed array.

参数

array

number[]

The packed array.

startingIndex?

number

The starting index of the element to be unpacked.

result?

PolygonGeometry

The object into which to store the result.

返回

void
