Perspective Drawing
Hello viewers, today I will introduce you to Perspective Drawing. Perspective Drawing is a technique of depicting volumes and spatial relationships on a flat surface. It is how you view an object as it leads to the vanishing point(s) and towards receding parallel lines appear to converge. Objects are foreshortened as it gets closer to vanishing point. Below are some examples of 1-Point, 2-Point & 3-Point Perspectives.

One-Point Perspective
One-Point Perspective only requires 1 vanishing point. In Helen South's article about one-point perspective, she effectively informs you about vanishing points and how it applies to perspective drawing. "To draw one-point perspective, we arrange our subject so that one set of
visible lines has a vanishing point right in front of us, and the set
at right-angles goes out to infinity on each side." Objects that appear in front are obviously larger than of those that appear behind. An object gets smaller in the back as it progresses towards the vanishing point. Here's an image of what it looks like:

Two-Point Perspective
Two-Point Perspective requires 2 vanishing points. In order to successfully execute a two point perspective drawing, you have to use 2 vanishing points on two different sides. V.Ryan created a tutorial on how to work with two-point perspectives. According to Ryan, two point perspective uses two vanishing points and
when an object is drawn in this way it is even more realistic than if it
were to be drawn with a single vanishing point. The tutorial in the link is highly recommended if you plan on learning how to execute two-point perspective in your works. Here's an image on where you can place your two vanishing points:
Three-Point Perspective
Three-Point Perspective requires 3 vanishing points. It is definitely more difficult than dealing with 1 or 2-point perspectives. Three-point perspective is usually used for buildings. In the link provided here and below, there is a tutorial on how to render and use 3-point perspective. I personally never dealt with or experimented with more than 2 vanishing points, (well, I might have) but not in the ways that are shown in the tutorial. In three point perspective, every right-angle line in the drawing will
eventually converge on one of three perspective points. Although it's very challenging, Three-point perspective is the most accurate way
of drawing the world around you in three dimensions. Here's an example of what it looks like:
