KBE3D / KBCore / Cesium / EllipsoidGeometry

类: EllipsoidGeometry

A description of an ellipsoid centered at the origin.

示例

const ellipsoid = new Cesium.EllipsoidGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  radii : new Cesium.Cartesian3(1000000.0, 500000.0, 500000.0)
});
const geometry = Cesium.EllipsoidGeometry.createGeometry(ellipsoid);
