In this lesson nosotros are going to create a iii-Indicate Perspective view drawing of the same discipline covered in the previous ii-Betoken Perspective drawing tutorial (Fig ane). This type of 3-indicate perspective view angle is referred to every bit “high 3/4 view perspective” if you are above the object looking down, or “Depression three/four View Perspective” if you are beneath the object looking up. When observing an object from above or below, all vertical, parallel lines on the object will also converge at a stock-still indicate which is called the “zenith” (highest signal) or “nadir” (lowest point). This type of perspective illustration is also known as a “bird’southward eye view” or “ariel view” or “worm’due south middle view” of the subject.

As with the previous tutorial on two-point perspective, these types of perspective grids are all-time done using vector drawing software such as Adobe Illustrator, Photoshop vector or CorelDRAW. This is due to the vector software’s ability to accept one of a line’s anchor-betoken’due south be dragged to a new location while the other anchor-point remains stationary.

Left and right vanishing points on horizon line

Following the instructions in the previous ii-point perspective tutorial, our first line to describe will be the moving picture-plane
Fig. 2. From this point, we will follow every step that is described in the 2 pt perspective tutorial with one notable exception; the addition of a third vanishing point – the “nadir” (Fig 2), or everyman point.

You would use the exact same technique if y’all were looking up at the subject (Fig 3) but instead of projecting vertical lines downwards towards the Nadir you would be projecting the vertical construction lines upwardly towards the “Zenith.” This angle of view would be known as a “Worm’s Eye View.”

We are now set up to start projecting lines to the vanishing points. Referring to
Fig. 4, depict lines from both horizon vanishing points (LVP & RVP) to the reference points of our bailiwick (green dots). You volition also project lines from our tertiary vanishing bespeak, the “Nadir.”

For this demonstration I have chosen an arbitrary placement for the Nadir. The further the Nadir is from the subject (downward), the less “forced’ the perspective volition look. “Forced Perspective” gives the impression that you are viewing the discipline through a “fish eye” or “wide angle” lens of a photographic camera. By moving the Nadir downward, you will “flatten” the perspective giving the impression that you are viewing the subject through a “telephoto” or “long” lens.

nosotros will get-go to construct the secondary features of the discipline (dark-green dots). The first step will be to establish the secondary vertical plane shown in
Fig. five. Then we volition construct or secondary horizontal airplane shown in
Fig. vi.

Three-point perspective mapping

Once we take completed our construction lines we will starting time to “draw” our final black outlines past using Adobe Illustrator’s “Scissors (C)” tool to cutting the construction lines (in the location of the green dots) and give them new thickness and colour attributes. For additional information on this line technique go to the “Decision-making Line Weights & Quality” Adobe Illustrator Tutorial.

3 pt perspective construction

Go on the process of cutting the construction lines and using Illustrator’s “Eyedropper (I)” tool to sample the attributes of your other black outlines. As was shown in Fig. 7, make your cuts in the location of the green dots.

Three point perspective grid

At present that you lot have completed the process of cutting out all of the necessary lines in out discipline, you can eliminate the lark of the construction lines. Cut them back using the “Scissors (C)” tool, but continue them handy in the event that you need to change the position of, or add boosted lines to the subject field.

Three point perspective drawing

The concluding step is to darken the object’south construction lines, and add weight to all of the exterior and outside border lines, to increase readability
Fig. 10. See the “Controlling Line Weights & Quality” Adobe Illustrator Tutorial for additional information on “line” control.

Final 3 pt perspective construction example 10

The dazzler of learning these perspective filigree techniques is that they can be used to deconstruct, or “reverse engineer” a photograph by tracing several parallel and perpendicular line to their vanishing point on the horizon. Wherever two parallel lines intersect you will have discovered the location of the horizon line. Past repeating this process on the left and right sides of an object, y’all can then utilize each side’due south vanishing point to depict a line between the ii to form the horizon.

In the line drawing case below, this complex technical illustration of a cruise send was created using a basic three-bespeak perspective grid as a starting indicate, then fleshing-out all of the ship’s exterior details and constructing all of the internal information.

Complex 3-point perspective grid sample

In the example higher up, we used iii-point perspective because the view of the transport was hundreds of feet above the horizon line, looking down on the ship from a classic bird’s eye view. By using this bending of view, all of the vertical lines converge at as key nadir located far below the subject.
