new Cesium.RectangleOutlineGeometry(options)
engine/Source/Core/RectangleOutlineGeometry.js 272

A description of the outline of a a cartographic rectangle on an ellipsoid centered at the origin.
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
rectangle Rectangle A cartographic rectangle with north, south, east and west properties in radians.
ellipsoid Ellipsoid Ellipsoid.WGS84 可选 The ellipsoid on which the rectangle lies.
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 0.0 可选 The distance in meters between the rectangle and the ellipsoid surface.
rotation number 0.0 可选 The rotation of the rectangle, in radians. A positive rotation is counter-clockwise.
extrudedHeight number 可选 The distance in meters between the rectangle's extruded face and the ellipsoid surface.
Throws:
  • DeveloperError : options.rectangle.north must be in the interval [-Pi/2, Pi/2].
  • DeveloperError : options.rectangle.south must be in the interval [-Pi/2, Pi/2].
  • DeveloperError : options.rectangle.east must be in the interval [-Pi, Pi].
  • DeveloperError : options.rectangle.west must be in the interval [-Pi, Pi].
  • DeveloperError : options.rectangle.north must be greater than rectangle.south.
使用示例:
const rectangle = new Cesium.RectangleOutlineGeometry({
  ellipsoid : Cesium.Ellipsoid.WGS84,
  rectangle : Cesium.Rectangle.fromDegrees(-80.0, 39.0, -74.0, 42.0),
  height : 10000.0
});
const geometry = Cesium.RectangleOutlineGeometry.createGeometry(rectangle);
