Description 描述

A Camera is a device through which the player views the world.

Camera是一个设备，玩家通过它看世界。

A screen space point is defined in pixels. The bottom-left of the screen is (0,0); the right-top is (pixelWidth,pixelHeight). The z position is in world units from the camera.

屏幕空间点用像素定义，屏幕的左下为(0,0);右上是（PixelWidth，pixelHeight）.Z的位置是以世界单位衡量的到相机的距离。

A viewport space point is normalized and relative to the camera. The bottom-left of the camera is (0,0); the top-right is (1,1). The z position is in world units from the camera.

视口空间点是规范的并相对于相机的。相机的左下为（0,0）；右上是（1,1）；Z的位置是以世界为单位衡量的到相机的距离。

A world space point is defined in global coordinates (eg. Transform.position).

世界空间点是以全局坐标定义的（例如：Transform.position）。
