3 d paintings on the asphalt. How it's made, how it works, how it works

Of course, any of you have seen graffiti on the walls at least once in your life, in reality or in photos - it doesn’t matter. However, there is such a type of drawings as 3D graffiti. The pictures are so real that it’s hard to believe your eyes!

With these street drawings Russian cities turned into a real street art gallery.

Our Russian artists decided to surprise citizens in earnest. These voluminous graffiti can hardly be distinguished from reality. Cars in a hole, huge cliffs on the road and much more in this collection.

Although 3d drawing is called a drawing, it can also be done with paint, where, logically, it would be more correct to call it 3d painting on asphalt, but it so happened that we began to call it a drawing; let me remind you that abroad it is most often called 3d street painting - 3d street painting, although sometimes you can find the term 3d drawings like we have.

1. In the previous post, we built a grid in perspective reduction on a plane (on our asphalt), according to the selected parameters, the dimensions of the grid squares are 50x50 cm (length of the segment AB). The height of the human figure in the picture and the height of the viewer located at the inspection point is 170 cm, the distance to the inspection point is 2 meters.
As you can see in the photo below, by placing our apple sketch on the resulting mesh, 3d drawing from the inspection point on site it should look exactly the same as in the sketch, i.e. without distortions or deformations.

2. Now we need to draw a grid without distortion, this is our projection sketch, with which we will work on the site and transfer the image to the asphalt.
Our grid is built on the edge of the picture plane, which is a straight line for us H, the grid will be parallel to the picture plane and perpendicular to the base plane, i.e. the “asphalt”. The size of the grid squares is still the same - 50 cm; in the drawing, of course, you have it in the scale you chose.

3. Next, watch your hands... We number the squares for convenience. Let's conduct a beam, I called it " projection beam", from the inspection point N, at the point of any intersection of our drawing with the grid that lies in our perspective, I chose the edge of an apple leaf - it is located on the line of our grid in perspective (the base of the square C2). Intersecting our usual grid, which is parallel to us, the projection beam hits a point, which is the edge of our apple leaf.

4. In this clever way we find all the intersection points on our grid. Points that fall on the center line are found using the proportional calculation method.
To achieve a more accurate result of constructing parts and lines 3d drawing, the grid is specified by a smaller cell step.
We connect all the points with a smooth line, as it was in kindergarten once upon a time...
3d drawing the projection sketch is ready!
As you can see from the result obtained, our sketch turned out to be deformed. Now all that remains is to transfer it to the asphalt in nature, where you have already drawn out the grid and are sitting and waiting..

Using the same principle, the image is built on walls and ceilings. This is where the fairy tale ends...
P.S. And don't forget that 3d drawing This is primarily a drawing that requires drawing skills, mastery of color and composition, in otherwise the work may not be effective.
Thank you for attention!
You can get acquainted with my works here.

From the editor: In this article the artist Alex Maksiov will talk about the principles of creation 3D paintings on the asphalt. By a new author Artifex vast experience in this matter: he has created dozens of three-dimensional illusions all over the world!

The word asphalt refers to the horizontal plane on which we walk every day. It could be concrete, a wooden base, glass or even sand - yes, yes, now there are 3D drawings on sand! It just so happened that this type of drawing is usually called “on asphalt”, and in the original, in English, it is written as 3D street painting.

So... Many of those who are now reading this article are already familiar with this type street art from photographs found on the Internet. Maybe some of you have seen 3D drawings live, or maybe you tried to create them yourself.

Surely most of you have wondered, “But what about street artists achieve such an effect? I’m sure that some of you have already exclaimed: “What’s secret here!? This is an elementary projection of an image onto a plane!” Exactly so, but I would also clarify that this is projection + perspective. Although, of course, these are interacting concepts.

So where do you start working on a 3D drawing? Like all artists - from determining the plot and developing a sketch, which depends on the size of the site. You ask: “How does the plot depend on the size of the site?” And I will answer you that a drawing on asphalt is a projection onto a plane, which is at an angle to us and has its own perspective reduction.

If you decide to depict an object that is larger than a person - say, an adult bear attacking a person, then such a drawing will stretch for many meters. This is provided that the height from which a person looks at the drawing is equal to his average height. Therefore, sometimes artists can use a combination of a plane under their feet and a wall, or even two walls.

In this example, you can see how the dimensions of the image change when projected onto a plane by the line of sight. And the sharper this angle is, the more elongated the drawing will be.

Once you have decided on the sketch, you need to transfer it to the plane. How to do this? Some of you have already exclaimed: “With the help of a projector!” Yes, but there is one small condition: the drawing must be completed within one daylight hours (for example, at a festival). Under this condition, the projector cannot be used because the projected image cannot be seen in bright light. What to do?

First we will need to build a grid in space. This method is familiar to artists and architects of the relevant educational institutions, although some of you may have encountered the basics in drawing lessons. The apple drawing will look like this.

You can see how it deforms on the plane, so you only need to look at it from one point. Usually the viewing point for viewers is marked with a special sign, which makes it clear where exactly you need to be or film.

So, if you are planning to photograph 3D drawings, look for this sign!

In this post I will talk about the principles of creation 3D drawings on asphalt and not only on it. The word asphalt means a horizontal plane on which we walk every day, it can be concrete and a wooden base, glass and even sand, yes, yes, now there is such a thing - 3d drawing on the sand. It just so happened that we began to call it “on the asphalt,” apparently because in childhood we said: "Chalk drawing on asphalt" although they were often painted more on concrete, it is possible that the word concrete does not sound. Abroad in literal translation - 3d street painting in English. 3d street painting.

Many of you who are now reading this article are already familiar with this type of street art from photographs that were found on the Internet or maybe even some of you saw 3d drawings live, or maybe even tried to create it with his own hands, and probably the majority wondered, how street artists are seeking 3d effect?
I’m sure that some of you have already exclaimed: “By, what’s secret here!?...This is elementary projection of an image onto a plane!" And they will be right. I would clarify that this is projection + perspective, although of course the concept projections cannot be separated from prospects, these are interacting concepts.

So where does work begin? 3d drawing? And the work begins, like with all artists, with defining the plot and developing a sketch, which depends on the size of the site on which it will be performed. drawing. You may ask how does the plot depend on the size of the site?

To do this, you need to understand that a drawing on asphalt is a projection onto a plane, which is at an angle to us and has its own perspective contraction, and if you decide to depict an object that is larger than human height, let’s say an adult bear attacking a person, who will be the person being photographed, then such drawing in our case it will stretch for many meters, this provided that the height at the viewing point from which a person looks at the drawing is equal to the average height of a person. Therefore, sometimes artists can use a combination of a plane under the feet and a wall, or even two walls, which uses three and four planes (floor, ceiling and two walls) - the corner part of the room.

In this image you can see how the dimensions of the image change when projected onto a plane by the line of sight. And the sharper the angle of the line of sight to the asphalt plane, the more elongated the pattern will be.
Yes, everyone knew this without you, move on!

After you have decided on the sketch, you need to transfer it to a plane, in our case asphalt. How to do this?
Some of you have already exclaimed, yes, with the help of a projector! Yes, I will answer, it is possible with the help of a projector, but there is one small condition,drawingyou need to complete it within one daylight hours, as this can happen, suppose onfestival, in which the process of using the projector becomes impossible - the projected image is simply not visible in bright light. So how!?...

To do this, I will introduce you to the subject a little bit at a time. perspective and the method of constructing geometric objects in space - architect's method. Why geometric? Because first we will need to build a grid in space. This method is familiar in to a greater extent artists and architects relevant educational institutions, although someone has encountered the basics in the subject of drawing.

From the inspection point 3d drawing should look exactly like your sketch.

At the same time, on the asphalt, the apple pattern will look like this (top view). You can see how the pattern on the plane is deformed, so on 3d drawing or whatever else they might call him anamorphic drawing, not to be confused with amorphous! :) you need to look at it from only one point.
The diagram shows the human field of vision, approx. 120°

The viewing point for the viewer is indicated by such a sign (which I use) or any other, making it clear to the person that they need to be and film right here and in this particular direction. So what to look for high-quality photography I need just such a sign.

A couple of photos to understand how much the drawing changes in size.
On this photo through the camera lens from a designated inspection point.

That's how drawing transforms (view from the back side)
The drawn sewer hatch, which looks from the inspection point (where the tripod is) as a round lying pancake, the width of which is almost twice as long as the length, actually has the shape of an elongated oval, which has the opposite values - the length is greater than the width.

An example of using two planes for 3d drawing

What does such a deformation look like? drawing and from another viewing point.

First you need to set the size of the rectangular area that will capture yourdrawing on asphalt and determine perspective scale, namely length and width scale. To do this, you need to mark the horizon on a piece of paper and draw a line H , parallel to the horizon, this line is the edge of the picture plane in our drawing, which we will get to later; on asphalt, this line is the edge of a rectangular grid, which will be divided into squares measuring 50x50 cm.

This size is set arbitrarily by the artist, depending on the complexity of the image, according to the principle, the more details, the smaller the squares - for more precise definition positions of lines in the drawing.
We all remember that the horizon passes at the level of a person’s eyes, provided that the line of sight of the person looking at this figure is at the same height, that is, roughly speaking, if these figures are of the same height. And of course, if someone is taller or shorter, our horizon line changes.

Thus, knowing the height of a person (take average height 170 cm) we can set the footage on the picture plane, i.e. on the line H.
Next we draw a center line, which is at an angle of 90° to the edge of the picture plane, in this case to the line H.

For convenience, I divide the meter segments into floors and connect them to a point P on the horizon , thus receivingvanishing point Pand the scale of the length of the segments, which are equal to 50 cm.

Now the main thing, we need to determine width scale or you can also say depth scale a segment 50cm long. Simply put, we need to determine how visually the grid will shrink in perspective when placed on the asphalt. I recommend initially stocking up on a larger paper format for the drawing.

We set the distance to the main viewing point (from which the public will take photographs3d drawing) that is, to the edge of your drawing (or rather, to the edge of your future grid on the asphalt) I set 2 meters, the artist arbitrarily sets the distance that he needs, but I don’t think it makes sense to make it less than 1.5 meters.
On the centerline of our drawing, from the edge of the picture plane, what is the line H , set aside a distance of 2 meters, resulting in a segment C N. This point itself N for the further construction of the drawing does not play a role.

Next we need to get the remote point D1 on the horizon, from which the ray will intersect the picture plane at an angle of 45°, at the point C, this will help us determine the vertex of the square. To do this, we set the distance to be twice the height of the human figure, since the figure is the object from which we measure. Why 2 times from the picture plane? The reason is the structure of the human eye; our grip angle is greater in width than in height. For more or less normal, not distorted perception, we need to be at a distance from the object twice its height)

Thus we get the point Q(We won’t need it on site). From the main vanishing point P Let's set aside (you can use a compass) a segment equal to PQ on the horizon line, thus obtaining a point D1 And D2, most often it will extend beyond the sheet of paper, so the segment PQ divided by 2 to get a point D½ and four for the point D¼. Passing the ray through the points D1,C we get a straight line that intersects the plane of the picture at an angle of 45° in perspective.

Received point B1 segment B.P.is the vertex of the square, the segmentB,B1-side 50cm long in perspective.

As I said above, the remote point D1 goes beyond a sheet of paper, cut for convenience D1,P divided into four parts and we get a point D¼
Using remote point D¼keep in mind that in in this case rays intersect the side of the square B1,C1 from a different angle (this in prbl. 75° ) to the picture plane. And to find the intersection point, the segment B.C. is divided into four equal parts like any other segment on the line of the picture plane, from the intersection point a straight line is drawn to the vanishing point P, from D¼ V WITH- the point of intersection will determine the side B1,C1 which is how the ray conducted from D1 V WITH.

In such a cunning way at the intersections of rays from a distant point with rays of cutsAP, B.P., C.P., DP, EPwe get a grid measuring 2 by 2 meters in perspective reduction with the size of square sections 50x50 cm. Voila!

The height of the human figure in the picture and the height of the viewer located at the inspection point is 170 cm, the distance to the inspection point is 2 meters.
As you can see in the photo below, by placing our apple sketch on the resulting mesh, 3d drawing from the inspection point on site it should look exactly the same as in the sketch, i.e. without distortions or deformations.

Now we need to draw a grid without distortion, this is our projection sketch, with which we will work on the site and transfer the image to the asphalt.
Our grid is built on the edge of the picture plane, which is a straight line for us H, the grid will be parallel to the picture plane and perpendicular to the base plane, i.e. the “asphalt”. The size of the grid squares is still the same - 50 cm; in the drawing, of course, you have it in the scale you chose.

Next, watch your hands... We number the squares for convenience. Let's conduct a beam, I called it " projection beam", from the inspection point N, at the point of any intersection of our drawing with the grid that lies in our perspective, I chose the edge of an apple leaf - it is located on the line of our grid in perspective (the base of the square C2). Intersecting our usual grid, which is parallel to us, the projection beam hits a point, which is the edge of our apple leaf.

In this clever way we find all the intersection points on our grid. Points that fall on the center line are found using the proportional calculation method.
To achieve a more accurate result of constructing parts and lines 3d drawing, the grid is specified by a smaller cell step.
We connect all the dots with a smooth line, as it was once in kindergarten...
3d drawing the projection sketch is ready!
As you can see from the result obtained, our sketch turned out to be deformed. Now all that remains is to transfer it to the asphalt in nature, where you have already drawn out the grid and are sitting and waiting.

Using the same principle, the image is built on walls and ceilings. This is where the fairy tale ends.
And don't forget that 3d drawing This is, first of all, a drawing that requires drawing skills, mastery of color and composition, otherwise the work may not be effective.

Any aspiring artist can do this on asphalt or paper. To do this, you need to follow simple tips.

How to learn to draw 3D drawings for beginners

To become a 3D artist, try learning how to draw simple volumetric figures. An ideal place to start is to try to depict a cube, ball, pyramid, star, cylinder, cone.

To make a three-dimensional 3D picture, carefully study the shape of the depicted object, all its bulges and depressions. Look how the light falls. Certain parts of the figure are quite dark, while others receive bright light and produce bright highlights. Don't forget that any object provides a shadow.

The best way to learn to draw 3D with simple pencils with different hardness. For this it is better to purchase a special set. Soft pencils give darker and thicker lines, hard ones draw thinner and lighter. Also, to obtain a three-dimensional image, it is necessary to increase and decrease the pressure on the pencil where necessary.

How to draw 3d drawings on paper

Make a printout on a color printer. To make the picture clearer, it is advisable to use laser models and photo paper.

3D drawings on asphalt are drawn using cans of aerosol paints or colored crayons.

The difficulty in using the former is to find a large number of the shades you need. But learning to draw 3D drawings on asphalt correctly using spray cans is quite difficult. To spray paint in thinner streams, you can use an airbrush.
