ExtentGeometry

ExtentGeometry

new

A Geometry that represents geometry for a cartographic extent on an ellipsoid centered at the origin.

Parameters:
Name Type Argument Default Description
options.extent Extent A cartographic extent 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 extent 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 extent, 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.extrudedOptions Object <optional>
 Extruded options
Properties
Name Type Argument Default Description
height Number <optional>
 Height of extruded surface.
closeTop Boolean <optional>
 true true to render top of the extruded extent; false otherwise.
closeBottom Boolean <optional>
 true true to render bottom of the extruded extent; false otherwise.
Throws:
  • DeveloperError : options.extent is required and must have north, south, east and west attributes.
  • DeveloperError : options.extent.north must be in the interval [-Pi/2, Pi/2].
  • DeveloperError : options.extent.south must be in the interval [-Pi/2, Pi/2].
  • DeveloperError : options.extent.east must be in the interval [-Pi, Pi].
  • DeveloperError : options.extent.west must be in the interval [-Pi, Pi].
  • DeveloperError : options.extent.north must be greater than extent.south.
  • DeveloperError : options.extent.east must be greater than extent.west.
  • DeveloperError : Rotated extent is invalid.
Example
var extent = new ExtentGeometry({
  ellipsoid : Ellipsoid.WGS84,
  extent : Extent.fromDegrees(-80.0, 39.0, -74.0, 42.0),
  height : 10000.0
});

Members

:GeometryAttributes

An object containing GeometryAttribute properties named after each of the true values of the VertexFormat option.
See:

:BoundingSphere

A tight-fitting bounding sphere that encloses the vertices of the geometry.

:Array

Index data that, along with Geometry#primitiveType, determines the primitives in the geometry.

:PrimitiveType

The type of primitives in the geometry. For this geometry, it is PrimitiveType.TRIANGLES.
