What role does the camera play in 3DMAX20 10? How to apply it to graphics?

The camera is used to determine the angle and range you need to watch.

When you left-click the perspective in the perspective window, there will be options for cameras and various views. When you choose the camera you set (such as Camera00 1) as the view, what you can see is no longer the perspective, but the image from your camera's perspective.

In addition, by setting the camera, you can make the animation path you need, which is the biggest role of the camera in 3D animation.
