BOATS, PERSPECTIVE AND REFLECTIONS

A rectangular box is made up of parallel lines, for the width, length and height. When viewed at an angle, the length and the width of the box recede away from us towards the eye level. Each side has its own vanishing point, but there is only one eye level. As these lines recede, they also appear to converge. If they went on into infinity, they would eventually meet at their respective vanishing points on the eye level. A line that is below the eye level appears to slope upwards as it recedes away from us, while lines above us appear to slope downwards as they recede.

Viewed from a lower 3/4 angle with the eye level cutting through the hull = 2 vanishing points Example 4

Example 1 Viewed from the front with the eye level above = 1 vanishing point

Viewed from a 3/4 angle with the eye level above = 2 vanishing points Example 3

Viewed from the side with the eye level above = 1 vanishing point Example 2
