Remember- in the one point and two point perspectives the viewer's line of sight is straight out to the horizon. In the three point perspective the line of sight has tilted up or down. Lines that represent verticals in the drawing are now vanishing to a third point. either above or below the horizon line, according to the tilt of the line of sight. Last week we drew a box in three point with the third point below the horizon. This week we drew a view looking up.
And here is another 'box method' sketch. In this case a car.
Using the horizon line to set up a 4'6" high box we establish vanishing points that help us keep all planes in perspective. The car was drawn while keeping in mind the two rough elevation sketches seen above. Adjustments were made as we drew to "make it look right" but the box and the vanishing points acted as references for the perspective of the more curved lines. This car belongs on the used car lot! Draw your own.
