const geometry = Cesium.BoxOutlineGeometry.createGeometry(box);

参数

Object with the following properties:

参数

The minimum x, y, and z coordinates of the box.

参数

The maximum x, y, and z coordinates of the box.

属性

packedLength

static packedLength: number

The number of elements used to pack the object into an array.

方法

fromDimensions()

static fromDimensions(options: { dimensions: Cartesian3; }): BoxOutlineGeometry

Creates an outline of a cube centered at the origin given its dimensions.

参数

options

Object with the following properties:

dimensions

Cartesian3

The width, depth, and height of the box stored in the x, y, and z coordinates of the <code>Cartesian3</code>, respectively.

返回
