new Cesium.SphereOutlineGeometry(options)
engine/Source/Core/SphereOutlineGeometry.js 31

A description of the outline of a sphere.
参数名称 类型 描述信息
options object 可选 Object with the following properties:
参数名称 类型 默认值 描述信息
radius number 1.0 可选 The radius of the sphere.
stackPartitions number 10 可选 The count of stacks for the sphere (1 greater than the number of parallel lines).
slicePartitions number 8 可选 The count of slices for the sphere (Equal to the number of radial lines).
subdivisions number 200 可选 The number of points per line, determining the granularity of the curvature .
Throws:
  • DeveloperError : options.stackPartitions must be greater than or equal to one.
  • DeveloperError : options.slicePartitions must be greater than or equal to zero.
  • DeveloperError : options.subdivisions must be greater than or equal to zero.
使用示例:
const sphere = new Cesium.SphereOutlineGeometry({
  radius : 100.0,
  stackPartitions : 6,
  slicePartitions: 5
});
const geometry = Cesium.SphereOutlineGeometry.createGeometry(sphere);
