CorridorGeometry

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

描述一条走廊。走廊几何可以同时用 Primitive 和 GroundPrimitive 渲染。
Name Type Description
options object 具有以下属性的对象：
Name Type Default Description
positions Array.<Cartesian3> 定义走廊中心的笛卡尔坐标数组。
width number 走廊两侧边缘之间的距离（以米为单位）。
ellipsoid Ellipsoid Ellipsoid.default optional 要用作参考的椭球体。
granularity number CesiumMath.RADIANS_PER_DEGREE optional 每个纬度和经度之间的距离（以弧度为单位）。决定缓冲区中的位置数量。
height number 0.0 optional 椭球表面与坐标之间的距离（以米为单位）。
extrudedHeight number optional 椭球表面与拉伸面之间的距离（以米为单位）。
vertexFormat VertexFormat VertexFormat.DEFAULT optional 要计算的顶点属性。
cornerType CornerType CornerType.ROUNDED optional 决定角落的样式。
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
});
