+### Unity 预览界面
+#### 预览界面
+在Unity编辑器界面上可以看到除了Game视图、Scene视图，其他的视图也会出现绘制三维物体的地方，比如检视器的预览窗口，当选中网格时，会对网格进行预览，如下所示：
+![](https://gitcode.net/hankangwen/blog-image/-/raw/master/pictures/2022/01/12_20_46_52_20220112204650.png)
+绘制的方法都是使用 UnityEditor 未公开文档的PreviewRenderUtility类进行的。
+#### 检视器预览界面
+资产或脚本实现预览窗口可参考Editor类的文档说明，重载带有Preview关键字的接口。
+#### 开启预览功能
+默认脚本对象的检视器窗口是没有预览窗口的，如下所示：
+![](https://gitcode.net/hankangwen/blog-image/-/raw/master/pictures/2022/01/12_20_51_42_20220112205141.png)
+想要开启预览窗口，那么得创建自己的检视器窗口类，然后重载HasPreviewGUI接口，完整代码如下：
+```c++
+using UnityEngine;
+public class PreviewExample : MonoBehaviour
+{
+}
+using UnityEditor;
+using UnityEngine;
+[CustomEditor(typeof(PreviewExample))]
+public class PreviewExampleInspector : Editor
+{
+    public override bool HasPreviewGUI()
+    {
+        return true;
+    }
+}
+```
+可以看到有黑色的预览窗口了，如下所示：
+![](https://gitcode.net/hankangwen/blog-image/-/raw/master/pictures/2022/01/12_21_4_19_20220112210419.png)
+#### 标题栏绘制
+默认显示的是物体的名称，重载 GetPreviewTitle 接口可以更改标题名称：
+```c++
+public override GUIContent GetPreviewTitle()
+{
+    return new GUIContent("预览");
+}
+```
+标题栏右边可以绘制其他的信息或者按钮等，重载 OnPreviewSettings 接口方便对预览窗口进行控制：
+```c++
+public override void OnPreviewSettings()
+{
+    GUILayout.Label("文本", "preLabel");
+    GUILayout.Button("按钮", "preButton");
+}
+```
+#### 预览内容的绘制
+最后预览内容的绘制，只需要重载 OnPreviewGUI 接口即可：
+```c++
+public override void OnPreviewGUI(Rect r, GUIStyle background)
+{
+    GUI.Box(r, "Preview");
+}
+```
+最后显示如下所示：
+![](https://gitcode.net/hankangwen/blog-image/-/raw/master/pictures/2022/01/12_21_15_5_20220112211505.png)
+
+#### 摄像机渲染
+不仅仅在预览窗口进行绘制控件，还可以绘制三维物体，实质是绘制独立的摄像机所照射的信息，例如动画片段预览窗口：
+
+鼠标可以拖动旋转等，还可以看其他方向，就像操作摄像机一样。
+
+这都是通过 PreviewRenderUtility 来实现的，对于这个类没有官方文档，可以通过网上其他人的分享，还有 UnityEditor 内部的使用来学习。
+
+#### 基础绘制
+PreviewRenderUtility 的构造和销毁，还有要预览物体的构造和销毁，以及调用绘制，以 BeginPreview 和 EndAndDrawPreview 包围，在其中进行摄像机的渲染 Camera.Render 调用，代码如下：

+        if (pe.previewGo != _lastGameObj)
+        {
+            _lastGameObj = pe.previewGo;

+        Camera camera = _previewRenderUtility.camera;
+        if (_previewInstance)
+        {
+            camera.transform.position = _previewInstance.transform.position + new Vector3(0, 5f, 3f);
+            camera.transform.LookAt(_previewInstance.transform);    
+        }
+        camera.Render();
+        _previewRenderUtility.EndAndDrawPreview(r);
+    }
+
+    private PreviewRenderUtility _previewRenderUtility;
+    private GameObject _previewInstance;
+    
+    private void InitPreview()
+    {
+        if (_previewRenderUtility == null)

+            _previewRenderUtility.cameraFieldOfView = 30f;
+        }
+
+        if (_canRefreshPreviewGo)
+        {
+            _canRefreshPreviewGo = false;
+            // 创建预览的游戏对象
+            CreatePreviewInstances();

+            _previewRenderUtility.Cleanup();
+            _previewRenderUtility = null;
+        }

+
+#### 拖动旋转
+在预览窗口鼠标拖动可以旋转进行预览，就像Cube物体预览一样。要想让摄像机旋转，得知道游戏对象的中心，才能绕着它进行旋转。

+    switch (current.GetTypeForControl(controlID))
+    {
+        case EventType.MouseDown:
+        {
+            bool flag = position.Contains(current.mousePosition) && position.width > 50f;
+            if (flag)
+            {
+                // 鼠标摁住拖出预览窗口外，预览物体任然能够旋转
+                GUIUtility.hotControl = controlID;
+                // 采用事件
+                current.Use();

+                EditorGUIUtility.SetWantsMouseJumping(1);
+            }

+            break;

+        case EventType.MouseUp:
+        {
+            bool flag2 = GUIUtility.hotControl == controlID;
+            if (flag2)
+            {
+                GUIUtility.hotControl = 0;
+            }
+
+            EditorGUIUtility.SetWantsMouseJumping(0);
+            break;
+        }

+            if (flag3)
+            {
+                // shift 加速
+                scrollPosition -= current.delta * (float) (current.shift ? 3 : 1) /
+                                  Mathf.Min(position.width, position.height) * 140f;
+                // 以下两条缺少任意一个，会导致延迟更新,拖动过程中无法实时更新
+                // 直到 repaint事件触发才重新绘制
+                current.Use();
+                GUI.changed = true;
+            }
+
+            break;

+
+#### 自定义视图的预览
+在自定义视图上的预览，可以采用类似以上的方式进行绘制，也可以创建相应的检视器类，直接调用绘制预览接口。代码如下：
+<details>
+  <summary><font color=darkred>查看代码</font></summary>
+  
+```c++
+using UnityEngine;
+using UnityEditor;
+
+public class PreviewExampleWindow : EditorWindow
+{
+    private Editor m_Editor;
+
+    [MenuItem("Example/PreviewExample")]
+    static void ShowWindow()
+    {
+        GetWindow<PreviewExampleWindow>("PreviewExample");
+    }
+
+    private void OnDestroy()
+    {
+        if (m_Editor != null)
+        {
+            DestroyImmediate(m_Editor);
+        }
+
+        m_Editor = null;
+    }
+
+    void OnGUI()
+    {
+        if (m_Editor == null)
+        {
+            // 第一个参数这里暂时没关系，因为编辑器没有取目标对象
+            m_Editor = Editor.CreateEditor(this, typeof(PreviewExampleInspector));
+        }
+
+        m_Editor.DrawPreview(GUILayoutUtility.GetRect(300, 200));
+    }
+}
+```
+
+</details>
+打开测试窗口，如下图所示：
