[]我想用代码来绘制一个3D球如何弄呢？看我写的

Laya3D.init(0, 0,true);

		Laya.stage.scaleMode = Laya.Stage.SCALE_FULL;

		Laya.stage.screenMode = Laya.Stage.SCREEN_NONE;

		Laya.Stat.show();

		

		

		var scene = Laya.stage.addChild(new Laya.Scene());

		

		var camera = scene.addChild(new Laya.Camera(0, 0.1, 100));

//		camera.transform.translate(new Laya.Vector3(0, 0.8, 1.0));

//		camera.transform.rotate(new Laya.Vector3(-30, 0, 0), true, false);

		camera.clearColor = null;

		camera.addComponent(CameraMoveScript);

		

		//球体

		var sphere = new Laya.SphereMesh(10,10,10);

		var sphereMesh = new Laya.MeshSprite3D(sphere);

		sphereMesh.transform.localScale = new Laya.Vector3(100, 100, 100);

		scene.addChild(sphereMesh);
