# Perspective Drawing – Methods for Creating Illusions of Depth

Perspective drawing is a useful skill to learn when we want to understand how to create realistic space in a drawing. Learning how to draw perspective gives us a better understanding of the three-dimensional aspect of objects and how they exist in space. Understanding the different perspective points concerning various perspective lines will be the distinction between one-, two-, and three-point perspective drawing. To draw in perspective, we want to understand the fundamentals of how the horizon line and the vanishing points. As we learn how to construct simple objects using perspective, we will see how objects are constructed in ways that are contextual to their surroundings.

## Before We Begin

In this tutorial, we will learn how to place objects in space. Perspective is about understanding the position from which objects are viewed. Different perspective points will define the visual aspects of an object accordingly.

This is because when we look at an object in space from a particular angle, our brain is simultaneously defining the space around the object as well. This peripheral ability allows us to see an object move away into the distance.

Based on which perspective we are looking at the object, this will determine how it moves into the distance. We define this visual quality in a drawing as one-point perspective drawing, two-point perspective drawing, and three-point perspective drawing. Let us see what materials we will need for this tutorial. ## Step-by-Step Instructions on How to Draw Perspective

Perspective drawing can be complicated, that’s why we will be breaking down the difference between one-point perspective, two-point perspective, and three-point perspective in this tutorial. We will be going through the basics of each by creating a series of cubes that function according to each perspective. We will see how we construct various perspective lines and how they slowly define each cube by merging into their perspective points.

We will learn about the horizon line and the vanishing point, the two key aspects that help us define three-dimensional objects in space.

The various points of perspective are what will govern the formation of each cube and ultimately will contextualize the object within the space that it exists. As we learn how to draw in perspective, we will find that it is not that hard, once we break down each aspect step by step.

### One-Point Perspective

One-point perspective is the simplest way of defining a space using a set of principles to define its proportional accuracy.  Again, because this is a single-point perspective, this means we are seeing an object vanish into a single distant point. This makes the edges of the cube lead toward the single vanishing point. Let us see how we construct objects with this one-point perspective rule.

#### Step 1: Draw the Horizon Line and Vanishing Point

Let us begin by drawing the horizon line. We do this by drawing a single horizontal line through our page. The horizon line defines the landscape and works as the reference for our eye-level view of a space.

This will define the space that cubes will exist in and how we perceive them. We can then proceed to make a single point on the horizon line. We want to keep this point quite central on the line. This is where the perspective lines will be drawn from which will help us construct our cubes.

#### Step 2: Drawing the First Cube

We will now proceed to draw a square under our horizon line. We can draw this square anywhere on the page, however, for collaboration, let us draw this square toward the left of the page. As long as it is under the horizon line, this is fine. Once we have our square drawn, what we will do is proceed to draw a line with our ruler, connecting the outer edges of the square directly to the vanishing point. By connecting all the edges of the square to the vanishing point we are defining the parameters that the cube will exist within. Once we have connected the edges of our square to the vanishing point with diagonal lines, we can then proceed to draw another square within those diagonal lines. The aim here is to allow your next square’s lines to remain parallel to the first square.

However, we keep these marks within the diagonal lines between our first square and the vanishing point. Once we have done that, we should be left with an elongated cube that seems to be extending into the distance. We can then take our pen and highlight the cube, just to emphasize its form on the page. This is the simple process of how we construct cubes within 1 point perspective. #### Step 3: Drawing the Second Cube

Now that we understand the fundamentals, we can now proceed to make another cube under the horizon line. This time let us make a smaller cube. By doing this we will see how it also defines the depth and distance of different cubes according to the one-point perspective.

As we draw a smaller square, we can connect its edges to the vanishing point with diagonal straight lines. Again, using the diagonal lines as a parameter for your second square, draw another square behind the first one. As we draw these squares within the diagonal lines that lead to the vanishing point, we are defining their motion and depth within the space.

We then connect these two squares within the diagonal lines to create a cube. We can then proceed to outline the cube with our pens. Outlining the cube is to highlight its shape to better understand how it appears in the space. Drawing cubes is the simplest way to understand shape and form from various perspectives. #### Step 4:  Drawing the Third Cube

We will now proceed to draw another square, however, this time we will draw the square above the horizon line toward the left of the page. We can draw this square slightly larger this time, just to give ourselves diversity in the scale of our cubes.

This helps create various depths and distances between the various cubes that we draw. Again, we then want to use our pencils and rulers to connect the edges of the square to the vanishing point. We can then proceed to follow the same process as before by drawing another square within the parameters of the diagonal lines that are connected to the square. Once we have another cube, we can then highlight it with our pens, giving us a more vivid cube in contrast to the page. We will also notice that there is a difference in how we view objects above and below the horizon line.

Imagine the horizon line is at eye level, if there are objects above it, it will appear as above eye level and the same goes for if it is below the horizon line. #### Step 5: Drawing the Fourth Cube

For this last cube, instead of drawing the square first, begin by drawing two diagonal lines into the right space of the page, above the horizon line. We can then proceed to draw a vertical line through these two diagonal lines.

This will be the length of a new square. We can then allow that vertical line to define one side of a square which we will construct from that single vertical line. This is another way of constructing a cube, whereby we do so by using the diagonal lines to define the size of the square rather than drawing the square first. Again, we can use the diagonal lines that are connected to the vanishing point and the edges of the square to define the parameters for another square. We then connect those two squares to create a cube.

This process is modular, by this I mean that we can construct cubes from the diagonal lines or by creating squares first. Again, as we draw our cubes above and below the horizon line, we will find that the horizon line is defining the eye level of the viewer. This means that if we draw objects above the horizon line, they will appear to be above our eye level. Whereas, if we draw objects below the horizon line it will appear as if the objects are below eye level. Lastly, we can then proceed to outline the next cube by using our pens. We want to outline our cubes with a pen to better emphasize the shape of the object and how it is formed within a one-point perspective landscape.

That is a breakdown of how to construct a one-point perspective drawing. ### Two-Point Perspective

The two-point perspective is quite similar to that of the one-point perspective, however, if you haven’t guessed yet, this time we are dealing with two vanishing points. Perspective drawing is about understanding various perspectives, in this case, we can imagine looking at the corner of a building, allowing us to see two of its sides. This means we will be able to see it moving in two different directions as if there were two roads we could see on either side of the building. Let us continue to draw cubes and see how we describe this quality from a two-point perspective.

#### Step 1: Drawing the Horizon Line and Two Vanishing Points

Let us begin by creating a horizon line. Remember, the horizon line is functioning at our eye level, anything above the horizon line is going to be perceived as above eye level and anything below will be perceived as below eye level.

We can then add two points at either end of our horizon line.

#### Step 2: Drawing the First Cube

We then proceed to make two points below our horizon line vertically parallel to one another. let us do this toward the left side of the page. These two points are going to be the edge of the cube that we look at from a front view. We then can connect two diagonal lines from our left vanishing point to each of these two points that we have drawn below the horizon line.

By doing so, we are creating the left side of the cube. Once we have done that, we can draw a vertical line connecting the two dots below the horizon line.  We then draw another vertical line parallel to that vertical line on the left within the parameters of the diagonal lines.

We should be left with a lopsided square within the diagonal lines. We then will draw diagonal lines from our other vanishing point, on the right side of our page, connecting to all the corner tips of the lopsided square. By doing so we are slowly constructing the cube. As we connect all the corners of the lopsided square to the vanishing point on the right side of the page, we are allowing a convergence of the perspective lines from both vanishing points.

These convergences will create intersection points that will help us to build the cube from a two-point perspective. We should be left with four diagonal lines two from each vanishing point. All four lines should meet at all four corners of our lopsided square. This should define the cube-like shape with a distinctly complete left side. We then will proceed to make another point on the bottom diagonal line from our right vanishing point. This point can be measured from the bottom corner of the square along the bottom right diagonal line. You could make it the same length as the vertical line of the square.

We then want to connect a line from this point to the left vanishing point. By doing so we will have developed another side of our square which you can then draw a vertical line from that point to the top-right diagonal line, parallel to the first vertical line of the cube. We then will be left with a cube, where all four diagonal lines, two from each vanishing point, connect to all the corners of the cube.

#### Step 3: Drawing the Second Cube

Again, we will draw two diagonal lines from the left vanishing point, instead, this time we will draw them above the horizon line. We want to draw them out toward the right side of the page above the horizon line. We will then begin to make a vertical line, connecting the endpoints of each diagonal line with a single vertical line. We can then add two diagonal lines from our right vanishing point, connecting to the top and bottom point of the vertical line. Allowing for both the right and left diagonal lines from both vanishing points to meet.

By following the same process as before, we can begin to construct our cube. Again, we will use the parameters of the diagonal lines to guide where we will place our next set of vertical lines. As we draw a vertical line on both the right and left sides of the first vertical line, we will allow the diagonal lines to define their height.

We can then connect the edges of the cube with diagonal lines that lead to both vanishing points. The way to tell how these cubes are accurately formed is by seeing if the diagonal lines from both vanishing points run through all corners of the cube. We then use vertical lines to connect the points of intersection of both sets of diagonal lines from both of the vanishing points.

By using the vertical lines, we can also see if the cube is proportional in form.

Once we have both our cubes, which we can see above and below our horizon line we can then proceed to highlight the cube with a pen. Again, drawing perspective is a unique way of understanding the form of objects not only from one, two, or three perspectives but also from understanding how we see them according to our eye level. Again, the way we understand if the cubes are correct is by seeing how two sets of diagonal lines from each vanishing point intersect. Wherever they intersect is where we will draw our vertical lines to define the edges of the cube.

Once we have done that, we highlight our cube with our pen to emphasize their form within the space. That’s how a two-point perspective works. Similar to the one-point perspective, however, we are using two vanishing points. Since there are two vanishing points, this means we allow the diagonal perspective lines, two from each vanishing point, to intersect.

This allows us to use these points of intersection to describe where we’ll draw the vertical lines of our cubes.

### Three-Point Perspective

We start with two vanishing points on the horizon line, just as before, but now we are going to place a third vanishing point below the horizon line centrally between the first two vanishing points. This will make an upside-down triangular shape which will govern how the cubes are formed through a set of lines. This will give the cube a more elongated quality as if we are looking down from a high position. With that said, let us go through the various steps from a three-point perspective.

#### Step 1: Drawing the Horizon Line and Two Vanishing Points

Once again, we begin by drawing a horizon line. The horizon line is the eye-level at which we see the landscape upon which we construct the objects. This helps us understand how the object is viewed, either above or below us.

In this case, we will be constructing objects that are seen below us.

#### Step 2: Drawing the First Cube

Once we have established two vanishing points on either side of our horizon line, we then will proceed to make a third point. This point is placed significantly below the horizon line, centrally between the other two vanishing points.

This should create an upside-down triangular formation. We then can draw a vertical line directly up the page starting from the third vanishing point. We then proceed to draw diagonal lines from the right and left vanishing points, to the third vanishing point at the bottom of the page. These lines are defining how we will construct the first cube. We can now proceed to do another set of diagonal lines starting from both vanishing points on the horizon line, leading to the third vanishing point.

This time allows the lines to connect slightly higher on the vertical line. Working with the top set of diagonal lines, we want to find a point along the top left diagonal line and make a dot.  We then want to use our ruler and connect that dot to the right vanishing point on the horizon line. We will draw a line until we reach the vertical line and stop there.

However, make sure that if the line had to continue it would connect through to the right vanishing point on the horizon line. We can proceed by using our ruler to connect the left vanishing point and the intersection point between the vertical line and the line that is connected to the vertical line. We then draw this line on the right side of the vertical line.

This will create a diamond-like shape that will function as the top of our cube.

We then proceed to connect the top part of the cube to the bottom part of the cube by drawing vertical lines between the top and bottom diagonal lines of the left vanishing point. We connect this vertical line from the left edge of the diamond shape to the bottom diagonal line. We can draw the same vertical line connecting from the right edge of the diamond shape to the bottom right diagonal line. These vertical lines run to the bottom diagonal lines, which should describe the shape of a cube.

We can then highlight the cube shape with our pens.

#### Step 3: Drawing the Third Cube

We begin by establishing the same set of three points. Two on either side of the horizon line and a third one placed significantly below the horizon line between the two vanishing points on the horizon line. This should have a triangular-like shape between all three points.

We can draw a vertical line through the page starting at the third point below the horizon line.

This time we will draw two diagonal lines from each vanishing point on the horizon line toward the bottom section of the vertical line. However, we are not connecting these diagonal lines to the third point at the bottom of the vertical line. We want these two diagonal lines to be slightly above the third point on the vertical line. We can now draw another diagonal line, from each vanishing point on the horizon line, towards the vertical line. These diagonal lines can be drawn significantly higher than the first two diagonal lines.

We want them to be quite close to the bottom of the horizon line.

We will now connect our ruler from the right vanishing point to the top-left diagonal line. We will then proceed to make a line along the ruler between the top-left diagonal line stopping at the vertical line. The line should seem as if it is going to connect to the right vanishing point. We can then do the same with the top right diagonal line and the left vanishing point. We connect them with a ruler as if we were to draw a line connecting them. However, we draw the line stopping at the vertical line.

We want this line to connect to the top diagonal line on the left side of the vertical line to create a diamond shape.

At the side points of the diamond shape, we want to connect our ruler between those points and our third vanishing point at the bottom of the page. However, as we draw a line down the page we will stop at the bottom diagonal lines. However, it should connect to the third point if you were to continue to draw the line beyond the bottom diagonal line. Once we connect a line between the side points of the diamond shape to the bottom diagonal lines, we should be left with a diagonal vertical line.

Those two lines should connect to the third vanishing point so that if they were to extend beyond the bottom two diagonal lines, they would meet each other at the third vanishing point.
