new Cesium.CorridorGeometry(options)
engine/Source/Core/CorridorGeometry.js 1072

A description of a corridor. Corridor geometry can be rendered with both Primitive and GroundPrimitive.
参数名称 类型 描述信息
options object Object with the following properties:
参数名称 类型 默认值 描述信息
positions Array.<Cartesian3> An array of positions that define the center of the corridor.
width number The distance between the edges of the corridor in meters.
ellipsoid Ellipsoid Ellipsoid.WGS84 可选 The ellipsoid to be used as a reference.
granularity number CesiumMath.RADIANS_PER_DEGREE 可选 The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
height number 0 可选 The distance in meters between the ellipsoid surface and the positions.
extrudedHeight number 可选 The distance in meters between the ellipsoid surface and the extruded face.
vertexFormat VertexFormat VertexFormat.DEFAULT 可选 The vertex attributes to be computed.
cornerType CornerType CornerType.ROUNDED 可选 Determines the style of the corners.
使用示例:
const corridor = new Cesium.CorridorGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  positions : Cesium.Cartesian3.fromDegreesArray([-72.0, 40.0, -70.0, 35.0]),
  width : 100000
});
