Mastering the techniques of perspective is crucial when it comes to painting and drawing a realistic scene. It is one of the ways for creating realism, believability, sense of scale and space on a 2-dimensional surface. Particularly when it comes to inorganic/ solid objects or environments, drawing perspective grid in a precise and correct way is super important.
There are many types of linear perspective techniques based on the view that one chooses. Below are the types of perspective and demo on how to use them.
1 point perspective:
In 1 pp, we have a horizon line, which is common to other types of perspective and we have a vanishing point. That vanishing point is the location where every angled line will converge to, except for perfect horizontal and vertical lines.
2 point perspective:
Here, just like others, we have a horizon line but in this, we have 2 vanishing points on that horizon line.
These vanishing points, the closer they are, the more distortion there will be. so, it’s best to put them a bit far from each other. How far? one might ask. although it’s a bit technical, but to save you headache, I will simplify. Try to put one vanishing point within the frame and the other one outside it. This is not the norm, and can both be inside but still far apart. There are a lot more factors involved like the cone of vision etc but we can cover that in a more advanced lesson but to be honest, we don’t get to go into much technicalities that often.
So, except for the vertical lines, all the angled lines will either go to the first or the second vanishing point.
3 Point perspective:
It’s Just like the 2 pp, except that this will also affect the vertical lines too. So, just to re-iterate. We have a horizon line and on that horizon line, we have 2 vanishing points. Now, depending on, if we look up or down, our 3rd vanishing point will be positioned either above the horizon line or below it.
I really need to mention this point here. In the real world, there can be as many vanishing points as we want. The common example would be, a table in a library and on top of the table there are many books placed in different angles, now, every book will follow its own vanishing point and that whole scenario will create numerous points of perspective.
Drawing that many perspective guides is unnecessary and can cause problems in image composition. So, in order to simplify the huge complexities of perspective, we try to reduce them and count them as 1 point, 2 point, 3 point perspective etc.
As artists, we need to free our minds from too many technicalities and spend that time in creating and imagining creative stuff.
