EarthSDK可以类似cesium加载点那种 建立一个父实体集来控制显示隐藏

var p = new XE.Obj.Pin(uia.earth);
var p2 = new XE.Obj.Pin(uia.earth);
p.position = [1.9748895674441815, 0.5216586947793432, 0]
p2.position = [1.9574436561344333, 0.5166830769150111, 0];
var g = new XE.SceneTree.Group(uia.earth)
g.children.push(new XE.SceneTree.Leaf(p));
g.children.push(new XE.SceneTree.Leaf(p2));
uia.earth.sceneTree.root.children.push(g)


Reproduce the example using XE.Obj.Pin, XE.SceneTree.Group, XE.SceneTree.Leaf, and uia.earth.sceneTree.root. Trace how the group’s visibility is represented or changed, then define done as being able to toggle the parent group and have its child pins show or hide together.
