ONE-POINT PERSPECTIVE

Perspective- portraying a three-dimensional object /space on a 2-dimensional surface

Vanishing point (VP)- Using one perspective, parallel lines converge to one point somewhere in the distance. This point is called the vanishing point (VP). This gives objects an impression of depth.

When drawing using one point perspective all objects vanish to one common point somewhere on the horizon.

ONE-POINT PERSPECTIVE

The sides of an object diminish towards the vanishing point. All vertical and horizontal lines though are drawn with no perspective. i.e. face on.

One point perspective though is of only limited use, the main problem being that the perspective is too pronounced for small products making them looking bigger than they actually are.

So when would you use one point perspective?

One area where one point perspective can be quite useful is for sketching room layouts

Although it is possible to sketch products in one point perspective, the perspective is too aggressive on the eye making products look bigger than they actually are.

VP

STEP 1

Draw the vanishing point in the center of the horizon line and label it.

STEP 2

Now draw a square or rectangle and label it "front face". Draw it in one of the lower corners so you have plenty of room to add more forms. You can continue to relate the drawing to the physical box model as you work.

STEP 3

Now connect three corners of your rectangle or square to the vanishing point. These are orthogonals. Draw lightly so you can erase!

STEP 4

Draw a horizontal line to end your form.

STEP 5

Draw a vertical line down from the horizontal line to complete the side.

STEP 6Erase the remaining orthogonals.

REMINDER

All perspective drawings start with the basic geometric shapes.
