unity全息技术入门打包至真机详解

项目基于unity2017.1

Step 1：导入模型，设置真机分辨率

模型坐标归0，这个不用说

由于我的手机是i7所以设置了1334*720的分辨率

Step 2：创建摄像机

新建一个空物体，归零坐标重命名为CameraManager，创建四个子物体Camera分别位于模型的前后左右

重点：前后左右的Camera保持对称即可，由于模型的大小不一所以摄像机的坐标会有偏差，调整四个方向的Camera角度使模型的顶部对屏幕的中央，这样投影出来的模型才不会翻

这个我的四个Camera坐标

Step 3：修改Camera属性

修改Camera的ClearFlags为Solid Color,计算Viewport Rect值，如果部分画面显示不出来修改Depth值(四个Camera设置为不同的值应该就可以了)

为了方便日后使用我直接用脚本，挂载到CameraManager上，设置分辨率，拖拽对应Camera到面板就可以了，最后复制Game模式控制台的参数就可以了

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;

public class CameraSetting : MonoBehaviour {
public Camera _topCamera;
public Camera _bottomCamera;
public Camera _leftCamera;
public Camera _rightCamera;
public int _width; //屏幕宽度
public int _high; //屏幕高度
public delegate void CameraSetDelegate(Camera TargetCamera);
public event CameraSetDelegate _cameraSetTopCamera;
public event CameraSetDelegate _cameraSetBottomCamera;
public event CameraSetDelegate _cameraSetLeftCamera;
public event CameraSetDelegate _cameraSetRightCamera;
Rect _cameraRect = new Rect();
private void Awake()
{

_cameraSetBottomCamera += SettingCameraBottom;
_cameraSetLeftCamera += SettingCameraLeft;
_cameraSetRightCamera += SettingCameraRight;
_cameraSetTopCamera += SettingCameraTop;
}
Rect OutRect(float width,float high,string cameraName)
{
_cameraRect.width = (float)Math.Round(((float)1 / 3 * high / width), 2);
_cameraRect.height = (float)Math.Round((float)1 / 3, 2);
switch (cameraName)
{
case "TopCamera":
_cameraRect.x = (float)Math.Round(0.5-_cameraRect.width/2, 2);
_cameraRect.y = (float)Math.Round((float)2/ (float)3, 2);
Debug.Log("Top"+_cameraRect);
break;
case "BottomCamera":
_cameraRect.x = (float)Math.Round(0.5- _cameraRect.width / 2, 2);
_cameraRect.y = 0;
Debug.Log("Bottom" + _cameraRect);
break;
case "LeftCamera":
_cameraRect.x = (float)Math.Round(0.5+ _cameraRect.width / 2, 2);
_cameraRect.y = (float)Math.Round((float)1 / 3, 2);
Debug.Log("Left" + _cameraRect);
break;
case "RightCamera":
_cameraRect.x = (float)Math.Round(0.5 - 3 * _cameraRect.width / 2, 2);
_cameraRect.y = (float)Math.Round((float)1 / 3, 2);
Debug.Log("Right" + _cameraRect);
break;
}

return _cameraRect;
}
private void SettingCameraBottom(Camera TargetCamera)
{
TargetCamera.rect = OutRect(_width, _high, "BottomCamera");
}
private void SettingCameraTop(Camera TargetCamera)
{
TargetCamera.rect = OutRect(_width, _high, "TopCamera");
}
private void SettingCameraLeft(Camera TargetCamera)
{
TargetCamera.rect = OutRect(_width, _high, "LeftCamera");
}
private void SettingCameraRight(Camera TargetCamera)
{
TargetCamera.rect = OutRect(_width, _high, "RightCamera");
}
private void Start()
{

try
{
_cameraSetBottomCamera(_bottomCamera);
_cameraSetLeftCamera(_leftCamera);
_cameraSetRightCamera(_rightCamera);
_cameraSetTopCamera(_topCamera);
}
catch (Exception e)
{

Debug.Log( e.Message);
}
}

}

模型顶部必须朝向中央(再次强调)

Step 4 打包真机

因为作者用的是ios，安卓也都一样，直接设置运行模式为横屏(防止投影时自动翻转)
