In one-point, lines are either vertical, horizontal, or recede toward the vanishing point. In two point, lines are either horizontal or receding toward one of the two vanishing points. In three-point perspective, all lines recede toward one of the three vanishing points. Those three vanishing points make the biggest difference between three-point and the other kinds of perspective drawing. Four point perspective is also called the infinity point view. It is a curved version of two point perspective. The images can represent a 360 degree angle panorama and even beyond 360 degrees to represent impossible scenes.
