1.摄像机组件

1.Clear Flags_clear target

There is nothing to fill where the game object needs to be rendered

1.SkyBox_天空盒子

We need to build a shader,在Standard上选择Skybox/6 Sided

 Then drag the picture of the skybox you found into the six faces（All six pictures I dragged are the same,Mainly to see the effect of the sky box）

 

 Finally drag this shader directly into the scene,This effect is formed （A professional skybox photo should be a continuous sky with no gaps）

The way to restore is here

2.Solid Color_单色填充

3.Depth only_Depth fill only

It is possible to overlay different depth camera renderings（If the content rendered by both cameras is at the same position on the screen,A larger depth value will overwrite the content with a smaller depth value）

This is the depth value,下面会详细介绍（详情看7.Rect_深度）

4.Dont Clear_The original game object is not cleaned up

At this point there is only one game object in the scene,The camera is the choice Dont Clear的模式的,Run it now,Let's see what happens

 This is the scene after dragging the object in motion

2.Background_背景色

3.Culling Mask_裁剪遮罩

 Controls the camera to render certain layers of game objects

在我们的Unity中,Each game object will have a hierarchyDefault

 This level is similar to a label,You can add your own name,But unlike labels,Levels can only be added at most32个

Return to the camera to openCulling MaskYou can see the hierarchy of all settings 

 If selected, the camera can see the game objects of this level,Uncheck it to see no game objects at this level

How should we set it in the code

Each level is preceded by a label,从0到31,2的n次方（nThe label before the hierarchy）In the code, we use the left shift operator to implement the check operation,如下

 4.Projection_投射方式

1.Perspective_透视相机

效果：近大远小

 You can see that the camera's field of view is like a cone,But let's zoom in

 There is still a cross section,Because the last thing our camera has in front of our eyes is a flat surface,So even set to minimum is a plane,如果是0It becomes a point,There is no such thing as flat vision

2.Orthographic_正交相机

没有近大远小的效果,What he shows is a rectangular field of view,如下

5.Clipping Planes_The distance of the camera's field of view

6.Viewport Rect_The position and size of the window

x y w h All represent proportions  从0 到 1  After adjustments can be found in oursGamesee inside the view

x y 为坐标  The reference coordinates are screen coordinates,左下角是（0,0）

w h 是大小

7.Rect_深度

The depth of the camera is used when there are multiple cameras in the scene,深度值越大,The higher the display is

例如小地图,We can set the depth value of the minimap to be larger than the scene camera,This allows the minimap to exist in front of the scene camera view

Main Camera：Viewport Rect:    X: 1     Y: 1     W: 1     H: 1             Depth:1

Camera：Viewport Rect:    X:0.5    Y:0.5    W:0.5    H:0.5             Depth:2

8.Target Texture_Specifies to render content rendered by one camera in oneRander Texture上面

This function can realize the projection of the picture seen by the camera onto the game object,例如：电视机,镜子,UIModel display of the interface, etc

首先创建一个Rander Texture 

found on the cameraTarget Texture,将Rander Texture拖入

再创建一个材质球,Place the shader on the Shader设置为Unlit/Texture（Remove the effect of lighting on the image）

然后把Rander Texture Drag onto the shader

 Finally drag this shader onto the game object,The game object is now ready to display the camera effect
