擴增實境技術是很棒的智慧行銷工具，一個業務出門，往往需要帶一大堆型錄和自己的名片，假如可以用自己的名片來代替型錄，而這個型錄又是3D而且有動畫功能，這應讓是很棒的工具，今天要跟大介紹就是擴增實境名片(Augmented Reality Business Card)。

解開壓縮檔後，在Unity打開，在Project/AppContent/Script目錄下，可以找兩個程式為ModelRotation.cs和SwipeImage.cs。
SwipeImage.cs的原始程式列表：
using UnityEngine;
using System.Collections;
[RequireComponent (typeof (BoxCollider))] //or other collider
public class ModelRotation : MonoBehaviour {
public float rotationSpeed;
public bool rightSide = false;
private bool onOff = false;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(onOff && !rightSide)
transform.Rotate(Vector3.up, rotationSpeed * Time.deltaTime, Space.World);
else if(onOff && rightSide)
transform.Rotate(Vector3.up, -rotationSpeed * Time.deltaTime, Space.World);
}
void OnMouseDown() {
if(onOff)
onOff = false;
else
onOff = true;
}
}
SwipeImage.cs是內嵌在動畫角色上，因此可以點選HatsuneRumba角色就可以查看程式內全域變數，可以看下圖右下角看到rotationSpeed和rightSide，就能改變其速度和旋轉方向。
ModelRotation.cs的全數變數在下圖右下方，有Page、Image、Sliding Speed、Model分別表示型錄頁數和型錄平面圖、滑動速度、以及3D模型。
