CylinderGeometry

new CylinderGeometry(options)

A description of a cylinder.

Name Type Description

options

Object

Object with the following properties:

Name	Type	Default	Description
`length`	Number		The length of the cylinder.
`topRadius`	Number		The radius of the top of the cylinder.
`bottomRadius`	Number		The radius of the bottom of the cylinder.
`slices`	Number	`128`	optional The number of edges around perimeter of the cylinder.
`vertexFormat`	VertexFormat	`VertexFormat.DEFAULT`	optional The vertex attributes to be computed.

Throws:

DeveloperError : options.length must be greater than 0.
DeveloperError : options.topRadius must be greater than 0.
DeveloperError : options.bottomRadius must be greater than 0.
DeveloperError : bottomRadius and topRadius cannot both equal 0.
DeveloperError : options.slices must be greater that 3.

Example:

// create cylinder geometry
var cylinder = new Cesium.CylinderGeometry({
    length: 200000,
    topRadius: 80000,
    bottomRadius: 200000,
});
var geometry = Cesium.CylinderGeometry.createGeometry(cylinder);
