WallOutlineGeometry

new WallOutlineGeometry(options)

A description of a wall outline. A wall is defined by a series of points, which extrude down to the ground. Optionally, they can extrude downwards to a specified height.

Object

Object with the following properties:

Name	Type	Default	Description
`positions`	Array.<Cartesian3>		An array of Cartesian objects, which are the points of the wall.
`granularity`	Number	`CesiumMath.RADIANS_PER_DEGREE`	optional The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
`maximumHeights`	Array.<Number>		optional An array parallel to `positions` that give the maximum height of the wall at `positions`. If undefined, the height of each position in used.
`minimumHeights`	Array.<Number>		optional An array parallel to `positions` that give the minimum height of the wall at `positions`. If undefined, the height at each position is 0.0.
`ellipsoid`	Ellipsoid	`Ellipsoid.WGS84`	optional The ellipsoid for coordinate manipulation

Throws:

DeveloperError : positions length must be greater than or equal to 2.
DeveloperError : positions and maximumHeights must have the same length.
DeveloperError : positions and minimumHeights must have the same length.

Example:

// create a wall outline that spans from ground level to 10000 meters
var wall = new Cesium.WallOutlineGeometry({
  positions : Cesium.Cartesian3.fromDegreesArrayHeights([
    19.0, 47.0, 10000.0,
    19.0, 48.0, 10000.0,
    20.0, 48.0, 10000.0,
    20.0, 47.0, 10000.0,
    19.0, 47.0, 10000.0
  ])
});
var geometry = Cesium.WallOutlineGeometry.createGeometry(wall);

Methods

staticWallOutlineGeometry.createGeometry(wallGeometry) → Geometry|undefined

Computes the geometric representation of a wall outline, including its vertices, indices, and a bounding sphere.

Name	Type	Description
`wallGeometry`	WallOutlineGeometry	A description of the wall outline.

Returns:

The computed vertices and indices.

staticWallOutlineGeometry.fromConstantHeights(positions, maximumHeight, minimumHeight, ellipsoid)

A description of a walloutline. A wall is defined by a series of points, which extrude down to the ground. Optionally, they can extrude downwards to a specified height.

Name	Type	Default	Description
`positions`	Array.<Cartesian3>		An array of Cartesian objects, which are the points of the wall.
`maximumHeight`	Number		optional A constant that defines the maximum height of the wall at `positions`. If undefined, the height of each position in used.
`minimumHeight`	Number		optional A constant that defines the minimum height of the wall at `positions`. If undefined, the height at each position is 0.0.
`ellipsoid`	Ellipsoid	`Ellipsoid.WGS84`	optional The ellipsoid for coordinate manipulation

Example:

// create a wall that spans from 10000 meters to 20000 meters
var wall = Cesium.WallOutlineGeometry.fromConstantHeights({
  positions : Cesium.Cartesian3.fromDegreesArray([
    19.0, 47.0,
    19.0, 48.0,
    20.0, 48.0,
    20.0, 47.0,
    19.0, 47.0,
  ]),
  minimumHeight : 20000.0,
  maximumHeight : 10000.0
});
var geometry = Cesium.WallOutlineGeometry.createGeometry(wall);

staticWallOutlineGeometry.pack(value, array, startingIndex)

Stores the provided instance into the provided array.

Name	Type	Default	Description
`value`	Object		The value to pack.
`array`	Array.<Number>		The array to pack into.
`startingIndex`	Number	`0`	optional The index into the array at which to start packing the elements.

Source: Core/WallOutlineGeometry.js, line 130

staticWallOutlineGeometry.unpack(array, startingIndex, result)

Retrieves an instance from a packed array.

Name	Type	Default	Description
`array`	Array.<Number>		The packed array.
`startingIndex`	Number	`0`	optional The starting index of the element to be unpacked.
`result`	WallOutlineGeometry		optional The object into which to store the result.
