The single point perspective drawing, is made up of a vanishing point, on the horizon line, where all construction lines, converge to give the impression of the object disappearing into the distance, as objects do, when we look at them in real life, this enables us to give our drawings, the impression of being three dimensional. Many illusions of depth, can be created by doing perspective drawing and most people find it very interesting, to do this type of drawing, in fact many people spend hours doing it because they can easily create, very dynamic 3D drawings, that look impressive.
How to draw perspective, using a single point, the most basic single point of all, can be done by putting a single dot or point, in the center of a piece of paper and then drawing perspective lines, from the center to the out side of the paper or drawing area, this then creates a single point perspective, if everything is then drawn in relation to these lines, it creates, the illusion of things, getting smaller, as they lead off into the distance, like they do in real life.
The drawing below, shows a distorted cup drawn in single point perspective, the cup looks distorted because the construction box, at the top and bottom, are on a slight angle, slanting down to the right, making it seem distorted.
In the drawing further down the page, below, the construction boxes are drawn head on and the horizontal lines are drawn, fairly accurately spaced out from each other, top and bottom making the shape, seem correct and not distorted like the cup drawing directly below. The other aspect of this drawing, is called an ellipse, which is the oval shape, made by circular objects, when looked at in perspective, this can be created by following the explanations in the drawings.
The drawing below shows a more detailed explanation, of how to draw ellipses in single point perspective, the basic formula for this type of drawing is made by using an horizon line, which can also be called the eye line. The horizon line is mostly, just a horizontal line drawn across the paper, where your eyes, would be level with, when looking at the object and the perspective point, would be placed on this line so everything in the drawing, would converge on this single point, creating the illusion of perspective.
How to draw an ellipse in single point perspective.
The humble graphite pencil is a great tool to use, as a first place to start because of the many, cool effects you can develop and implement into your drawings with it, like mark making, notice the different types of shading in the drawings above. There is a combination of tonal modeling, hatching and cross hatching, which are the main types of mark making used in most drawings.
Also the graphite pencil, is probably the easiest tool to get your hands on, for doing drawing of all kinds, including the single point perspective drawing, like in the examples above.
