Members

attributes :GeometryAttributes

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

See:

• Geometry#attributes

boundingSphere :BoundingSphere

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

indices :Array

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

primitiveType :PrimitiveType

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

Methods

<static> fromConstantHeights

A Geometry that represents a wall, which is similar to a KML line string. A wall is defined by a series of points, which extrude down to the ground. Optionally, they can extrude downwards to a specified height.

Parameters:

Name	Type	Argument	Default	Description
positions	Array			An array of Cartesian objects, which are the points of the wall.
maximumHeight	Number	<optional>		A constant that defines the maximum height of the wall at positions. If undefined, the height of each position in used.
minimumHeight	Number	<optional>		A constant that defines the minimum height of the wall at positions. If undefined, the height at each position is 0.0.
ellipsoid	Ellipsoid	<optional>	Ellipsoid.WGS84	The ellipsoid for coordinate manipulation
options.vertexFormat	VertexFormat	<optional>	VertexFormat.DEFAULT	The vertex attributes to be computed.

Throws:

DeveloperError : positions is required.

Example

var positions = [
  Cartographic.fromDegrees(19.0, 47.0, 10000.0),
  Cartographic.fromDegrees(19.0, 48.0, 10000.0),
  Cartographic.fromDegrees(20.0, 48.0, 10000.0),
  Cartographic.fromDegrees(20.0, 47.0, 10000.0),
  Cartographic.fromDegrees(19.0, 47.0, 10000.0)
];

// create a wall that spans from 10000 meters to 20000 meters
var wall = new WallGeometry({
    positions : ellipsoid.cartographicArrayToCartesianArray(positions),
    topHeight : 20000.0,
    bottomHeight : 10000.0
});
