RectangleGeometry

RectangleGeometry

new

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

Parameters:
Name Type Argument Default Description
options.rectangle Rectangle A cartographic rectangle with north, south, east and west properties in radians.
options.vertexFormat VertexFormat <optional>
 VertexFormat.DEFAULT The vertex attributes to be computed.
options.ellipsoid Ellipsoid <optional>
 Ellipsoid.WGS84 The ellipsoid on which the rectangle lies.
options.granularity Number <optional>
 CesiumMath.RADIANS_PER_DEGREE The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.
options.height Number <optional>
 0.0 The height from the surface of the ellipsoid.
options.rotation Number <optional>
 0.0 The rotation of the rectangle, in radians. A positive rotation is counter-clockwise.
options.stRotation Number <optional>
 0.0 The rotation of the texture coordinates, in radians. A positive rotation is counter-clockwise.
options.extrudedHeight Number <optional>
 Height of extruded surface.
options.closeTop Boolean <optional>
 true true to render top of an extruded rectangle; false otherwise. (Only applicable if options.extrudedHeight is not equal to options.height.)
options.closeBottom Boolean <optional>
 true true to render bottom of an extruded rectangle; false otherwise. (Only applicable if options.extrudedHeight is not equal to options.height.)
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 options.rectangle.south.
  • DeveloperError : options.rectangle.east must be greater than options.rectangle.west.
Example
// 1. create an rectangle
var rectangle = new Cesium.RectangleGeometry({
  ellipsoid : Cesium.Ellipsoid.WGS84,
  rectangle : Cesium.Rectangle.fromDegrees(-80.0, 39.0, -74.0, 42.0),
  height : 10000.0
});
var geometry = Cesium.RectangleGeometry.createGeometry(rectangle);

// 2. create an extruded rectangle without a top
var rectangle = new Cesium.RectangleGeometry({
  ellipsoid : Cesium.Ellipsoid.WGS84,
  rectangle : Cesium.Rectangle.fromDegrees(-80.0, 39.0, -74.0, 42.0),
  height : 10000.0,
  extrudedHieght: 300000,
  closeTop: false
});
var geometry = Cesium.RectangleGeometry.createGeometry(rectangle);
