Unity3D基于陀螺仪实现VR相机功能

  Unity自带陀螺仪功能，今天就利用陀螺仪实现一个VR相机功能。步骤如下：

1. 打开Unity，创建一个新的C#脚本GyroController.cs,并挂在MainCamera游戏对象上，如图：
   
   
   代码如下：

   using UnityEngine;
   using System.Collections;
   public class GyroController : MonoBehaviour
   {
   // Fields
   private readonly Quaternion baseIdentity = Quaternion.Euler(90f, 0f, 0f);
   private Quaternion baseOrientation = Quaternion.Euler(90f, 0f, 0f);
   private Quaternion baseOrientationRotationFix = Quaternion.identity;
   private Quaternion calibration = Quaternion.identity;
