KBE3D / KBCore / Cesium / SphereOutlineGeometry

类: SphereOutlineGeometry

A description of the outline of a sphere.

示例

const sphere = new Cesium.SphereOutlineGeometry({
  radius : 100.0,
  stackPartitions : 6,
  slicePartitions: 5
});
const geometry = Cesium.SphereOutlineGeometry.createGeometry(sphere);

参数

Object with the following properties:

参数

参数

The count of stacks for the sphere (1 greater than the number of parallel lines).

参数

The count of slices for the sphere (Equal to the number of radial lines).

参数

The number of points per line, determining the granularity of the curvature .
