new Cesium.BoxGeometry(options)

描述以原产地为中心的立方体.

Name Type Description

options

object

下列属性的对象 :

Name	Type	Default	Description
`minimum`	Cartesian3		框的最低x,y,和z坐标.
`maximum`	Cartesian3		框的最大x,y,和z坐标.
`vertexFormat`	VertexFormat	`VertexFormat.DEFAULT`	optional The vertex attributes to be computed.

Example:

const box = new Cesium.BoxGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  maximum : new Cesium.Cartesian3(250000.0, 250000.0, 250000.0),
  minimum : new Cesium.Cartesian3(-250000.0, -250000.0, -250000.0)
});
const geometry = Cesium.BoxGeometry.createGeometry(box);

     -70.0, 35.0,
     -75.0, 30.0,
     -70.0, 30.0,
     -68.0, 40.0
]));
const box = Cesium.BoxGeometry.fromAxisAlignedBoundingBox(aabb);

Example:

const box = Cesium.BoxGeometry.fromDimensions({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  dimensions : new Cesium.Cartesian3(500000.0, 500000.0, 500000.0)
});
const geometry = Cesium.BoxGeometry.createGeometry(box);
