Camera animation, the first perspective problem? Animator, come in!

The railing is below. The first and first perspective is the subjective lens, which is equal to the picture that your eyes can see when you are in the position of the person in the painting.

"If it is the first type, the track is still below, isn't it the same as when the head is up?" It's different, because at this time the ground is above and the sky is below ~

Coherently, this transformation is a process, and the line of sight rotates 180 degrees. That is, when you actually ride a roller coaster, you will feel that you are not spinning, and the world is spinning ~ ~ ~ The reference is different ~
