Quadrilateral Perspective

HEIGHT OF THE HORIZON LINE

We normally use the horizon line height at 1.70m, because this is the average height of a man.

If we want to dislocate this line upwards or downwards we have to adopt the same system used for the horizon line at 1.70m.

We have to calculate a distance of 3m between the view point and the distance line. That is the same distance that we should have between the vanishing point and the depth point on the horizon line.

In order to provide a better understanding, in the following pages I make a brief study dislocating the horizon line 50cm upwards and 50cm downward.

HOW TO DISLOCATE THE HORIZON LINE

For better understanding of this process we have to carry out an examination of the agreement existing among the parts of the system, in order to check the harmony that involves this overlapping of images.

By means of sketched arches, as shown in the graphs in the following pages, we will be able to see a pentagonal harmony that involves the whole system.

Leonardo da Vinci depicted the pentagon as the symbol of life. Its symmetry is easily found in nature, botany and zoology.

I believe that the new basic concept resulting from this overlapping of images can be considered scientific in view of the satisfactory results of the practical experiment. The drawings present genuine images.
