new Cesium.EllipsoidOutlineGeometry(options)
engine/Source/Core/EllipsoidOutlineGeometry.js 49

A description of the outline of an ellipsoid centered at the origin.
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
radii Cartesian3 Cartesian3(1.0, 1.0, 1.0) 可选 The radii of the ellipsoid in the x, y, and z directions.
innerRadii Cartesian3 options.radii 可选 The inner radii of the ellipsoid in the x, y, and z directions.
minimumClock number 0.0 可选 The minimum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.
maximumClock number 2*PI 可选 The maximum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.
minimumCone number 0.0 可选 The minimum angle measured from the positive z-axis and toward the negative z-axis.
maximumCone number PI 可选 The maximum angle measured from the positive z-axis and toward the negative z-axis.
stackPartitions number 10 可选 The count of stacks for the ellipsoid (1 greater than the number of parallel lines).
slicePartitions number 8 可选 The count of slices for the ellipsoid (Equal to the number of radial lines).
subdivisions number 128 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:

  radii : new Cesium.Cartesian3(1000000.0, 500000.0, 500000.0),
  stackPartitions: 6,
  slicePartitions: 5
});
const geometry = Cesium.EllipsoidOutlineGeometry.createGeometry(ellipsoid);
