KBE3D / KBCore / Cesium / RectangleOutlineGeometry

类: RectangleOutlineGeometry

A description of the outline of a a cartographic rectangle on an ellipsoid centered at the origin.

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);

参数

Object with the following properties:

参数

A cartographic rectangle with north, south, east and west properties in radians.

参数

The ellipsoid on which the rectangle lies.

参数

The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.

参数

The distance in meters between the rectangle and the ellipsoid surface.

参数

The rotation of the rectangle, in radians. A positive rotation is counter-clockwise.

参数

The distance in meters between the rectangle's extruded face and the ellipsoid surface.
