There are two camera projections used in Unity: perspective and orthographic. With perspective projection, the camera renders a scene based on the camera angle, as it exists in the scene. Using this projection, the further away an object is from the camera, the smaller it will be displayed. This mimics how we see things in the real world. Because of the desire to produce realistic games, or games that approximate the realworld, perspective projection is the most commonly used in modern games. It is also what we will use in our Cucumber Beetle game.

The other projection is orthographic. An orthographic perspective camera renders a scene uniformly without any perspective. This means that objects further away will not be displayed smaller than objects closer to the camera. This type of camera is commonly used for top-down games and is the default camera projection used in 2D and Unity's UI system.

We will use perspective projection for our Cucumber Beetle game.
