Hi everybody, this time our topic is linear perspective. linear perspective drawing is the art of creating the illusion of depth on flat surface of sketch. In perspective, all the objects seem to gradually decrease in size when the distance between them and viewer increase. And each of the sets of parallel lines coming out from the object in this case appear to meet at one particular point. Speaking of linear perspective, we have to notice this system we apply generally to the books like object, I mean the rectangular boxes. So we use it for tourism, rooms, furniture and Of course the streets with buildings, city landscapes.

All the boxes surrounding us in daily life usually are standing on the horizontal surfaces, horizontal planes. And how we look depends on our position more precisely on the level of our eyes. level of ice is horizontal plane true, but we see like line. This line we call the line of horizon. Here are boxes on this gauge. First Box is the low level service it's topside.

Second is over eye level and we see it both inside. Third books is directly on the eye level. To the dawn see near its bottom side no talk. This third box is in possession of a billion seen from the street. Our eye level normally is higher than base over building. All the parallel lines are getting closer and closer with a distance.

You can remember how part an alliance of railway tracks seem to meet at a distant point were poorer lines belonging to the horizontal plane meet at the point on the line of horizon. This point is called the vanishing or melting point. Lines meeting of a moderation point are known as our toggles or convergence lines are two mostly used perspective schemes, one point perspective and two point perspective. Here we are speaking of quantity of Melton points. In one point perspective scheme our line of sight is directed in parallel with lines of depth of our boxes. Here is the top view they are outside of viewpoint in the scheme.

And when we are looking from viewpoint, we see line of sight like point on the horizon line, it is the melting point, all the rest of the lines of the meet at this point. vertical lines in one point perspective scheme are vertical and horizontal lines are horizontal. It is very convenient scheme because here is only one melting point and it is placed in Third of the sketch, but this time over linear perspective has its flow. It looks sometimes not very realistic. And threads are not always organized like chessboard. One point perspective we use when we are drawing objects facing us.

In two point perspective scheme, our line of sight is directed diagonally relatedly to the basis of our boxes. And we have two melting points. One from the left another from variety, each one for one set of parallel lines. Only lines of vertical set are vertical. This type of linear perspective is more realistic, but it has its flow to usually both melting points. Far away outside of our sketch page.

There are more than two types of perspective schemes. But for beginning, one point perspective and two point perspective give us enough freedom and sketching to achieve a good result in big variety of landscape. And knowing these schemes on location, you can choose the correct position to draw a sketch. Before sketching, we can draw a small schematic sketch to put horizon line and all the melting points in proper place and take a look of all the perspective books in our sketch. Now you can try to build up a couple of small sketches with boxes using two types of perspective schemes, one point perspective and two point perspective. It makes theory less abstract.

And more usable. In the next videos, I am going to build up examples of landscapes based on one point and two point perspective schemes. And of course, I'll show you some of my tricks and hints for avoiding unnecessary work and travel. See you later. Bye bye
