How to draw a house in an isometric projection and in a linear perspective

Very often there is such a question: "How to draw a house?" The simplest way that kids and their parents use is a flat image. That is, drawing a square or a rectangle, the front wall facing the observer, above it - a triangle-roof, windows, pipes. But this is the so-called "children's option." And how to draw a house so that it looks more real? Here it is necessary to get acquainted with several scientific concepts.

How to draw a house in an isometric view?

For the first time, we come across this method in the study of trigonometry, as well as in drawing lessons. Drawing a cube in the lessons of trigonometry, we get a visually almost real look in a three-dimensional image. And all sides of it remain the same size, and the front - even has right angles. The method of depicting objects in isometric projection is used in engineering when drawing out details on drawings, in computer-aided design systems, and in computer games. And since you can draw a house in an isometric projection using the cube drawing algorithm, you need to start with a square or a rectangle: it all depends on what the front wall of the depicted object is. Next, draw a rear wall, identical to the front, placing its base slightly above the front wall and sliding it to the right or left. The third stage is the connection of the angles of squares or rectangles. Now you need to remove the extra helper lines with the eraser. The roof must also be made in isometric projection. This special work will not be for those who have already encountered an algorithm of such constructions. Thus, the question of how to draw a house in pencil can be considered solved. But still, something in the resulting drawing is not quite true!

How to draw a house correctly?

The answer to this question was found in the fifteenth century by an architect from Italy Brunelleschi. It was he who drew attention to the fact that remote objects seemed to visually diminish. If we compare a tree standing about a meter from an observer, with the same tree at a distance of twenty meters, then the difference will be very noticeable. And the rails? Here they are under our feet, seemingly parallel to each other. But if you peer into the distance, you can see that the distance between them decreases and decreases. In the end, there is a mystical transformation: parallel rails "flock" to one point! This point is called a "vanishing point": all parallel lines are connected in it . Having determined the depth of the projection, that is the location of the point of descent of the straight lines with respect to the image object, the artist builds a model of the future drawing. An interesting fact is that the point of descent can be located far beyond the canvas where the painting is planned. Then they conduct (perhaps mentally) all straight lines. They should converge precisely at this point. Thus, the rear wall of the house is shorter than the front. But the image is more realistic than the drawing method, based on the isometric projection.
