A four-point perspective drawing is a type of drawing that contains four vanishing points. Two of the four vanishing points in this perspective are placed on each end of the horizontal line, and the other two vanishing points are placed anywhere above and below the horizon line (usually on both ends of the vertical line in the middle). This type of perspective drawing is almost the same as the five-point perspective: both use drawings in fisheye view, which is achieved with the use of curved gridlines. The difference is just that the five-point perspective uses a central vanishing point. Another difference is that while five-point perspective uses curved gridlines, four-point perspective only uses curved lines from top to bottom vanishing points and straight lines from vanishing points on the horizontal line.


How to Make a Four-Point Perspective Drawing

1. Draw a horizon and a vertical line and mark the four vanishing points: two points at each end of the horizon line and the other two at each end of the vertical line.


2. Draw perspective lines from the vanishing points on the horizon line.


3. Draw curved lines from the vanishing points on the vertical line.


4. Draw the objects and contents of your drawing following the guidelines and the rules of perspective drawing.


5. Continue working on the details of your drawing and finish it.
