What is a subjective perspective?

Subjectivity: it is a kind of consciousness and spirit of human beings, as opposed to objectivity. The so-called "subjectivity" means that the observer is the "master" and participates in the observed things. At this time, the nature and laws of the observed things change with the wishes of the observer.

Viewing angle: the angle formed by the line of sight and the vertical direction of the display, etc. When observing an object, the angle formed by the light at both ends of the object (up, down or left and right) at the center of the human eye.

Subjective perspective: it is the observer's perspective, and everything the observer sees with his eyes is within his perspective. It contains the will of the observer.
