KBE3D / KBCore / Cesium / EllipsoidOutlineGeometry

类: EllipsoidOutlineGeometry

A description of the outline of an ellipsoid centered at the origin.

示例

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

参数

Object with the following properties:

参数

The radii of the ellipsoid in the x, y, and z directions.

参数

The inner radii of the ellipsoid in the x, y, and z directions.

参数

The minimum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.

参数

The maximum angle lying in the xy-plane measured from the positive x-axis and toward the positive y-axis.

参数

The minimum angle measured from the positive z-axis and toward the negative z-axis.

参数

The maximum angle measured from the positive z-axis and toward the negative z-axis.

参数

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

参数

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

参数

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