下列属性的对象 :

Name	Type	Default	Description
`positions`	Array.<Cartesian3>		一系列确定走廊中心的位置.
`width`	number		走廊边缘之间的距离以米计.
`ellipsoid`	Ellipsoid	`Ellipsoid.default`	optional The ellipsoid to be used as a reference.
`granularity`	number	`CesiumMath.RADIANS_PER_DEGREE`	optional The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
`height`	number	`0`	optional The distance in meters between the ellipsoid surface and the positions.
`extrudedHeight`	number		optional 椭圆形表面与外凸面之间以米计的距离.
`vertexFormat`	VertexFormat	`VertexFormat.DEFAULT`	optional The vertex attributes to be computed.
`cornerType`	CornerType	`CornerType.ROUNDED`	optional Determines the style of the corners.

Example:

const corridor = new Cesium.CorridorGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  positions : Cesium.Cartesian3.fromDegreesArray([-72.0, 40.0, -70.0, 35.0]),
  width : 100000
});
