3d drawings, anamorphic secrets revealed.

3d drawing secrets.

The secrets of anamorphic 3d drawing and the amazing 3d drawings of street artists are no longer a secret any more. Follow the information contained on this page to reveal how it can be understood using a reference grid.

The video below shows a clipper lighter standing upright, nothing unusual or outstanding about that. The problem for many people, is to understand how it can be drawn to look like it is standing upright on flat 2d piece of paper. The secret of 3d drawings used by street artists that you need to know, is how to create the anamorphic illusion. If you know how to do this then it is not a problem. This is for those who do not know and would like a better understanding of this illusion.

Please see the video below to see this in action.

3d drawings using a camera.

Most street artists when creating these anamorphic 3d drawings use a camera to aid the process and describe their technique as drawing by eye. This means they are drawing by looking and using the camera as a guide for doing so.

In the image below a grid for reference has been drawn over the top of the lighter image and it has been cropped using the free GIMP photo editing software. Many artists use reference grids for getting their construction drawing accurately draw. This can be easily done using a pencil and straight edged ruler. If you don’t have access to photo editing software you can do it by using a print out of the image.

Using a camera viewing window to do 3d drawings.

The grid was drawn onto a piece of A1 cartridge paper to replicate the grid in the image above but as can be seen in the actual drawing, the grid drawing is far different from what can be seen through the camera lens. Notice that the grid drawing gets wider and wider, the further away it is from the camera. This is because of distance, indicting that the further away the object is, the bigger it needs to be in order to compensate for that distance.

The secret to these 3d drawings is realizing that this is what makes the technique work, being able to compensate for distance.

Below is an image of the camera showing both the drawing of the grid and the image, as seen through the camera lens, showing the difference between both. In the camera viewing window the grid looks like it is made up of squares. Where as the actual drawing isn’t made up of squares at all. This enables us to see how the camera lens at this viewing plane is distorting the drawing. Thus making it seem like it is made up of squares, when it is not. It is actually the same as any other perspective grid used to draw 3d drawings, that would be drawn to depict an object as if being looked at from the top. With the bottom tapering off into the distance as will be shown the the next image below this.

ViewOfTheGridThroughCamaraLens 3d drawings, anamorphic secrets revealed.
This image shows a view of the reference grid drawing and what it looks like when looking through the camera lens

Notice the two strips of masking tape placed down each side of the camera viewing window on the camera. These have been marked out with with lines equal in measurement. Using these measurements down the side of the viewing window of the camera, helped me to draw the grid. Using them as guides to see where to put the marks on the papers drawing surface. This was only necessary for the horizontal lines of the grid. The vertical lines can be measured after you have drawn the horizontal lines. This can be done by dividing the top and bottom lines by ten as in this example but this will depend on how many squares you want in your 3d drawing grid. The more squares you have in your grid to make 3d drawings. The easier it will be to complete your end drawing.

The secret of 3d drawings using a camera technique like the preferred choice of street artists.

In the image below you can see what the reference grid actually looks like when viewed from the front as you would normally. Please take notice of how the grid is wider at the top than the bottom. Also notice how the squares have become elongated and the horizontal lines are further apart as they get closer to the top of the paper. This image below shows what a perspective 3d drawing grid might look like if it was being used to draw an object, such as a building being viewed from above.

In the next image below I have drawn the Clipper lighter using the perspective grid for 3d drawings as a guide to accurately draw the lighter at this distorted perspective. Also notice how it can be seen in the camera viewing window. Notice how when looking at it through the camera viewing window it can be seen as a Clipper lighter standing up right and how the drawing grid also seems to be made up of squares.

The image below is a photograph of the 3d drawing, showing further how it looks just like any other drawing of a lighter standing upright. This gives you a visual demonstration of the optical illusion created by the anamorphic 3d drawings perspective and the focal plane of the camera.

The next image has been photographed slightly out of position and not at the correct focal plane. This enables you to be more able to see what it looks like in reality. It is revealing the distorted 3d drawing showing how it is much bigger at its furthest point from the viewing position.

Below you will find two more images to show what this drawing really looks like, when viewed as you would normally, the first one is the right way round and the second is being viewed, the wrong way round. Taking a look at these gives a better understanding of what the secret really looks like and helped me to visualize the distortion created by this unusual illusionary effect in the technique of making 3d drawings.

This image below is being shown the correct way up and is viewed from the front as you would any other drawing or image, directly from the front. It clearly shows how the drawing is distorted with the top being much wider than the bottom.

The image below has been turned up side down and reveals that looking at it this way around presents an image that resembles a perspective grid for depicting something that is tapering off into the distance. This is because that is what it is and would be doing. If something is close it will be big and as it gets further away it will get smaller, and smaller, the further into the distance it gets.

These 3d drawings can be created on a computer using GIMP photo editing software or any other photo editing software if you can distort images with a perspective tool. I found that if I took an image and placed a reference grid over the top of it on a separate layer in GIMP. Then merged both layers together and distorted it with the bottom being half as wide as the top, it created a good example of a drawing grid and picture combined. It produced an image that could be viewed with a camera to make it look like a normal image as shown in the example below.

Then there are some images below this, with shots taken at a distance of about 10 feet, 3meters, of a box placed on a sheet of A1 cartridge paper. This is more closer to the working distance experienced by street artists doing, 3d drawings on the street.

Julian Beever sidewalk art, chalk art.

Julian Beever sidewalk art and pavement chalk artist is now very well known on line. Over the past 6 or 7 years he has grown to become a very popular figure of discussion, which is because of his excellent 3d drawings having gained him widespread publicity, people sure like unusual subjects to discuss don’t they? In his work he creates the most amazing side-walk art by using anamorphic perspectives.

It could be said that he is an expert in the creation of dynamic optical illusions, with much experience in focal plane perspectives, this alone is to be admired, if not for any other reason than using anamorphic perspective and dynamic perspective to project himself across the world. Most of his work is celebrated by both people & businesses alike, having donated to this effort, allowing the opportunity for Julian’s work to exist. Once the work is completed it is abandoned, thus making it into what is called ephemeral art, an art form that has a short life span, something that eventually disappears like tears in rain.

JulianBeeverEquityBondMoneyVault Julian Beever sidewalk art, chalk art.


Julian Beever Sidewalk art.

In his book (Pavement Chalk Artist) he proclaims himself to be an entertainer, a showman, who started as a juggler and become a community activist, celebrated on a global scale as well as also being a very competent draughtsperson. Maybe he has a BA degree acquired at Leeds Polytechnic under his belt but after that he certainly went his own way and set his mark on the world populace.

All I can say about him really, is street art.

Because Julian Beever sidewalk art is unusual it has drawn attention to him from people all over the world but he also uses the same tools as the media networks that publicize the creations and portray the work. Works that can only be seen at their best through the eye of a camera lens, the same camera lens that was used to draw them. Coincidence or not these are the same visual tools that are used in the media networks and the social media networks that are enjoying a bonanza online at the present, photos say so much and are so easy to share. Grab attention for yourself by creating unusual art, 3d drawings that you can give to the news and wider media to be shared using the same tools everybody uses, coincidence or not, it works.

Julian Beever sidewalk art, 3d paintings don’t seem that difficult when you know the methods used to create them so please let me tell you how.

If you look at a pole or post that stands upright coming up from out of the ground, it will look like it is standing upright, it needn’t be a pole or a post, it can be anything, I use a post for explanation because it is a simple shape to use as an example.

Take a look at it from about 6 meters or 12 feet away, you will easily see the image as an item standing upright. You will see the post with all the differing angles that your brain will tell you is a post standing in an upright position from the ground. If you then draw a picture from the exact position you are standing in or take a picture from that position with a camera, it’ll look like it is a post standing in an upright position. If you then place that drawing, image or photo, flat on the ground it’ll look like a picture lying on the floor but it will never have the look of a post that is standing upright. It will not matter how big or small it is, not even if as large as the post itself, it’ll never really look like an upright post. If you move further back away from where it is lying on the floor, it’ll be increasingly difficult for you to identify what it is, as the angle which you’re looking at will make it more and more obscure. Julian Beever correctly refers to this angel as a viewing plane.

This is why it’ll not work.

When looking at 3D objects in reality our eyes see many different angles which are related to size, shape and distance, because you’ve 2 eyes, they see little differences and your brain informs you when the objects are 3-dimensional by understanding the meaning of all these different angels, it tells you that what you are seeing is 3 dimensional and has more than 1 side, which is what happens for you to see in 3D.

An example of this phenomenon can be seen in Julian Beever sidewalk art below, described as the swimming pool, in the High Street.

Below is the same Julian Beever sidewalk art example of a pool drawn on another high street from an opposite viewing position to show how these images are elongated in order to make up for the distance they are being viewed at and giving the illusion of them being closer than they actually are.

This helps the Julian Beever sidewalk art to achieve the illusion below by tricking the eye into thinking the focal length is shorter also enabling Julian to give the impression of a very small man on the top of a very large bottle.

BeerBottle Julian Beever sidewalk art, chalk art.

BeerBottleExample Julian Beever sidewalk art, chalk art.
Julian Beever 3D Beer Bottle chalk drawing that is the same as the one above it with slight changes.

In the Julian Beever sidewalk art pictures above, I’ve highlighted the lines where the paving slabs join, so you are able to see more clearly that the top part of the bottle is much bigger than it should be in relation to the bottom to create the illusion of it being closer.See how the base of the bottle in highlighted section 2 is just a little bit less than the width of one paving slab but the middle section just before the neck begins to taper in, highlighted section 1 is almost 2 slabs wide and should help you to understand that the drawing is being distorted in order to help make up for the distance it is at.

The distance is best seen by looking at the Julian Beever sidewalk art example aboveto see how small he is when compared with the girl and looking at the gradual reduction of the size of the tiles, they can also be used to help to measure out and map the construction of your drawing like using a grid. The top part of the drawing looks like it is about two tile’s wide and much larger than the base of the bottle in the drawing.

Trying to understand how Julian Beever sidewalk art works.

When doing a drawing of a post so that it gives the impression of it standing upright, it would have to be elongated so as to confuse your eyes and brain into thinking it was closer to you than it actually is. It would also have to be much wider at the top to compensate for the distance and the further away it is the wider it would have to be because something further away gets smaller, meaning you will need to make adjustments to it in order to be able to compensate for the distance. Doing this in the drawing will give the illusion of it being closer than it is in reality. The Julian Beever sidewalk art incorporates these measures into the drawings to make them more believable and 3D looking.

A bit like the picture below, where the horizontal drawing is much larger at the other end from the base because it is farther away so it is drawn bigger making it look like it is closer.

Below is yet another example showing Julian Beever sidewalk art that shows the image as being elongated so that it will work from the distance in which it is being viewed.

The image above of the world picture shows another example of stretching the drawing and how the drawn image becomes much bigger as a means of compensating for distance Please take a look at the Julian Beever sidewalk art video below.


Below, I’m told this is a different type of drawing that has been attributed as being more Julian Beever, sidewalk art in the form of being a more traditional mural on a wall, it’d not surprise me as it is somewhat in a similar style that is reminiscent of other drawings he has composed. If this is not one of his drawings then it would be safe to assume that there has been some influence from Julian Beever sidewalk art in this work and I’d be very surprised to find it hasn’t. I like it as it’s very dynamic and impressive.

It turns out that the above image was not by Julian Beveer and may have even been an insperation to him and not the other way round because this work was unveiled in 1975

It is fifty foot by seventy five foot mural titled TUNNELVISION by artist, Blue Sky.

Lighter Julian Beever sidewalk art, chalk art.
Image of a lighter standing upright

The challenge is to draw this lighter as an Anamorphic Perspective and reveal how it is done for those who are interested in finding out.

I took the lighter image and inserted a grid over the top to use as a reference grid for doing the drawing, I also want to show what the Anamorphic Perspective Grid actually looks like.

uprightLighterWithGrid Julian Beever sidewalk art, chalk art.
Lighter standing in upright position with reference grid over the top.

My camera was set up so I could draw the grid by using a camera as a viewer so as to be more able to draw the grid by using the viewing window of the camera as a guide. This is the same position and angle that the original lighter photograph was taken at.

LookingAtTheCamaraPosition Julian Beever sidewalk art, chalk art.
Image showing the camera angle in relation to the paper drawing area.

In the image below you can see both the grid that has been drawn onto the A1 sheet of cartridge paper and the image as seen through the camera lens. It shows the difference between the real drawing on the paper and the image being viewed through the lens and you can see that the image in the camera viewer is now symmetrical. This now enables me to copy the image from the lighter standing in upright position with reference grid over the top as above.

The image below shows what the Anamorphic Perspective Drawing Grid looks like when viewed directly from the front and looks like a normal perspective drawing grid that would perhaps be used for drawing a building looking down from the top.

This is my quick drawing of the lighter when viewed from the correct position with the camera as you can see it worked and the lighter actually looks like it is standing upright.

When you look at the image below it helps to get a look at it in its natural state as a flat drawing on a flat surface and help to get an understanding of how the Anamorphic Perspective works.

Below is the drawing completely in its natural viewing state as it can be seen directly from the front and now you can see how distorted it actually is. It is now quite easy to draw an Anamorphic Perspective grid because it is in actual fact a normal perspective drawing grid being looked at from upside down.

Single point perspective drawing.

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.

deformedcup Single point perspective drawing. 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.

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.
