关于ImageTarget的使用不再赘述，现在假设有个按钮，按下之后，imagetarget下的球体便变为正方体。

添加如下脚本，挂在ARCamera上。

using UnityEngine;using Vuforia;using System.Collections;public class ModelSwapper : MonoBehaviour {    public TrackableBehaviour theTrackable;    private bool mSwapModel = false;    // Use this for initialization    void Start () {        if (theTrackable == null)        {            Debug.Log ("Warning: Trackable not set !!");        }    }    // Update is called once per frame    void Update () {        if (mSwapModel && theTrackable != null) {            SwapModel();            mSwapModel = false;        }    }    void OnGUI() {        if (GUI.Button (new Rect(50,50,120,40), "Swap Model")) {            mSwapModel = true;        }    }    private void SwapModel() {        GameObject trackableGameObject = theTrackable.gameObject;        //把原来显示的模型隐藏掉。        for (int i = 0; i < trackableGameObject.transform.GetChildCount(); i++)        {            Transform child = trackableGameObject.transform.GetChild(i);            child.gameObject.active = false;        }        // 创建新物体cube        GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);        // 把cube的parent设置为trackable gameObject        cube.transform.parent = theTrackable.transform;        // 调整它的大小，使它能更好地适应target        cube.transform.localPosition = new Vector3(0,0.2f,0);        cube.transform.localRotation = Quaternion.identity;        cube.transform.localScale = new Vector3(0.1f, 0.1f, 0.1f);        // 保证它是激活的        cube.active = true;    }}
