In this lesson nosotros are going to create a iii-Signal Perspective view drawing of the same subject covered in the previous 2-Point Perspective drawing tutorial (Fig i). This type of three-point perspective view angle is referred to as "high 3/4 view perspective" if you are in a higher place the object looking downward, or "Low 3/four View Perspective" if you are below the object looking up. When observing an object from above or beneath, all vertical, parallel lines on the object will besides converge at a fixed point which is called the "zenith" (highest signal) or "nadir" (lowest bespeak). This type of perspective analogy is also known equally a "bird'due south eye view" or "ariel view" or "worm's eye view" of the subject field.

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

Following the instructions in the previous 2-point perspective tutorial, our kickoff line to draw will exist the picture-plane Fig. ii. From this betoken, we will follow every step that is described in the ii pt perspective tutorial with one notable exception; the addition of a third vanishing bespeak - the "nadir" (Fig 2), or lowest point.

You would use the exact aforementioned technique if yous were looking up at the subject area (Fig 3) but instead of projecting vertical lines downward towards the Nadir you would exist projecting the vertical structure lines upwards towards the "Zenith." This angle of view would exist known as a "Worm'southward Heart View."

We are now prepare to start projecting lines to the vanishing points. Referring to Fig. 4, draw lines from both horizon vanishing points (LVP & RVP) to the reference points of our subject (green dots). Y'all will also project lines from our third vanishing point, the "Nadir."

For this demonstration I have chosen an arbitrary placement for the Nadir. The further the Nadir is from the subject area (downward), the less "forced' the perspective will look. "Forced Perspective" gives the impression that you are viewing the subject through a "fish center" or "wide bending" lens of a camera. Past moving the Nadir downward, you will "flatten" the perspective giving the impression that you are viewing the subject through a "telephoto" or "long" lens.

In Fig. 5 & 6 we will start to construct the secondary features of the subject (green dots). The first step will exist to establish the secondary vertical plane shown in Fig. 5. Then we will construct or secondary horizontal plane shown in Fig. 6.

One time we have completed our construction lines we will get-go to "describe" our concluding black outlines past using Adobe Illustrator's "Pair of scissors (C)" tool to cut the construction lines (in the location of the green dots) and give them new thickness and colour attributes. For additional data on this line technique go to the "Decision-making Line Weights & Quality" Adobe Illustrator Tutorial.

Continue the process of cut the structure lines and using Illustrator's "Eyedropper (I)" tool to sample the attributes of your other black outlines. Equally was shown in Fig. 7, brand your cuts in the location of the green dots.

Now that you take completed the process of cutting out all of the necessary lines in out subject, you lot can eliminate the distraction of the construction lines. Cut them back using the "Scissors (C)" tool, but keep them handy in the upshot that you need to modify the position of, or add together additional lines to the discipline.

The last step is to darken the object's structure lines, and add together weight to all of the exterior and exterior edge lines, to increment readability Fig. x. See the "Controlling Line Weights & Quality" Adobe Illustrator Tutorial for additional information on "line" control.

The beauty of learning these perspective grid techniques is that they can be used to deconstruct, or "opposite 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. By repeating this process on the left and right sides of an object, you tin can then utilize each side's vanishing point to draw a line between the two to form the horizon.

In the line drawing instance below, this complex technical illustration of a cruise ship was created using a basic 3-point perspective filigree as a starting point, then fleshing-out all of the ship'south exterior details and constructing all of the internal information.

In the example higher up, we used 3-signal perspective considering the view of the send was hundreds of feet above the horizon line, looking downwards on the ship from a classic bird's eye view. By using this angle of view, all of the vertical lines converge at as central nadir located far beneath the subject.
