Polygonal graphics have become very popular in Lately and attracts the attention of some designers and artists. The image of portraits, objects or any drawings in the form of vector polygons looks spectacular and unusual.
Also, often polygonal drawing is used for the background, a slight color difference on the triangles creates an interesting volume effect. The process of creating such drawings will be discussed in this article, you will learn about manual and automatic methods of drawing with polygons.
Manual method of polygonal drawing.
An ideal tool for drawing polygons in Adobe Illustrator "Feather". Be careful that there are no gaps between the polygons. On small details a much larger number of elements is required so that they are not lost. It is desirable to build polygons in such a way that the image borders coincide with the polygon borders.
In order not to waste time drawing each triangle separately, you can drag one of the nodes on the copies (for more details, see video lesson at the end of the article).
But in any case, drawing polygons by hand takes a lot of time, especially at high detail. In addition, jambs may not be noticeable in the course of work, and then it is very inconvenient to edit them.
When the grid is ready, it's time to start coloring. Take the tool. Holding down a key ctrl select an element, and then, release and click with the eyedropper on the color under the selected element. The polygon is repainted in the desired color.
It looks much more interesting when the triangle has a gradient fill.
Automatic polygon drawing method.
A small program is able to perfectly draw polygons from your photo. Automatically, in any quantities and without jambs. And the best part is that coloring is also done automatically.
Unzip the downloaded archive. Follow this link \triangulator\triangulator\index.html. Run the index.html file. Drag your image into the field "Drop your bitmap here".
By clicking on the image with the mouse, you create nodes that automatically close and fill with a gradient color. Among the top buttons, you can add 25 polygons at once, save and change the transparency of the picture.
When the drawing is ready, you need to save it in vector format - Export to SVG: save this link as file. Right click on a line this link and select "save link as.." (in some browsers, the file format must be entered manually).
Export this file to CorelDRAW or Illustrator. Here you can correct defects and refine the image to the final result.
IN video lesson the process is described in more detail polygon drawing:

Job digital artist Mart Biemans titled "Feel it" combines neon color palette with dynamic triangles and other shapes, creating an eye-catching effect.
In this tutorial, Mart will talk about the techniques he used to create this work for online artistic group slashTHREE. You'll learn how to build an image by tracing a photo and creating geometric shapes, and then choose a color scheme and apply lighting effects.
These techniques can be adapted to many different styles - after completing the tutorial, repeat it and you'll see how far you can go.
Step 1
The first step to create a style of work is to choose the right photo.
I found my photo on dreamstime.com, if you want to use the same image, you can find it. Alternatively, find any similar photo. The picture should show the upper body and the profile of the face.
Place the photo in Photoshop's new portrait-sized document. A3. Make sure there is enough free space around the fields for the effects.
Step 2
Create a new layer below the photo, fill it with a muted color. This will be the background of our work. Add another layer above the photo and carelessly trace the outline of the model with the tool Feather(Pen Tool) by filling it over dark color. Hide this layer.
Create a third layer above all the others and stroke the shadows, filling them even darker. You don't need to leave a lot of details.
Step 3
Turn on the stroke layer, then repeat the previous step using different colors and blend modes to lighten up the work. Again, do not be zealous with detail. Be sure to lighten areas that have highlights in the original photo. Also remember to darken areas without lighting.
Step 4
On a new layer, draw a rectangle with a bright gradient. Duplicate it several times, resize it and fill it with different colors.
Create different variations using Edit > Transform > Warp(Edit > Transform > Warp). Give yourself free rein by creating some abstract shapes. Now place the shapes in the highlights and change the blending mode to Screen(screen).
Step 5
Some areas (such as hands) need to be visually separated. For this we use Pencil(Pencil Tool). Set the size to around 19 px if using Graphics tablet, make sure the checkbox Simulate pressure(Simulate pressure) is set. Draw black lines in the dark areas and white lines in the light areas.
Step 6
At this point, I wasn't happy with the color scheme, so I added an adjustment layer gradient map(Gradient Map) red-green color. If you want to repeat this step, set the blend mode to Light replacement(Lighten) with Opacity(Opacity) 100%.
Step 7
The drawing is still a bit flat. To give it depth, create a new layer, set its blend mode to Screen(screen). Use a large, round, soft brush with a light blue color to paint over the areas that need to be lightened.
Create another layer, set blend mode Soft light(soft light), Opacity(Opacity) 58%. With a black brush, paint over the areas where you want to enhance the shadows.
Step 8
Now let's add a "broken" effect using the tool Rectilinear lasso(Polygonal Lasso Tool). Select small areas of the image, click Ctrl+Shift+C to copy the merged version of all layers, and then paste it all on a new layer. Move the resulting pieces and repeat the step as many times as you want.
Step 9
Finish the job by adjusting the colors and adding some strokes Pencil(Pencil Tool) by making general form rougher. A similar effect is easy to achieve if you go to the menu Filter > Stylize > Edge Selection(Filter > Stylize > Find Edges), but the result may be of poor quality. Luckily, the filter works well with our image, as there's only a set of shadows and colors that the filter can easily stroke.
polygonal portrait or low poly - a popular art technique when processing photos.
The combination of Photoshop and Illustrator will give you the clearest and fastest results.
If you don't have Illustrator, you can use Inkscape or Xara.
In fact, once you understand the principle, you can use any tool.
But automation is no help to you. Not a single script will give half a good result.
Your brain, eyes and hands - that's the most important thing.
How to make a polygonal portrait in Photoshop
For those who are not looking for easy ways - read on!
The technical side of drawing a polygonal portrait is extremely simple and a real challenge.
for your patience, it will only be the monotony of work))
01. Choose the right look.
It is worth choosing a high-quality photo. Best suited for a portrait with bright
expressive details. You will need to zoom in, so choose a high resolution photo.
02. Tighten colors and contrast.
Throw the photo into Photoshop, add color and contrast. You need to pick up high enough
the contrast level, so that later it would be easier to select the color of the polygons. However, do not overdo it with
color and contrast. No more than 30%!
03. Reduce the quality.
If your photo is too big, reduce the resolution. 1000px on the long side is fine
enough. This will help you choose colors in the future. Fewer pixels - easier to find color.
04. Don't forget to work on different layers.
Now you can send the picture to Illustrator. Make one photo layer, color layer
and another layer for the polygonal mesh. You can add more in the future, but this is enough to get you started.
05. Making a colored background.
A polygonal portrait requires a lot of attention to detail. So it makes sense to make a clean background with
minimum gradient. Of course, the color based on the background of the picture is best. Skin tone will
look more advantageous.
06. Trying the line.
line of bright yellow color will look noticeable on most backgrounds. Line thickness -
about 0.5 points. In Photoshop, you can use the Polygonal Lasso.
07. Start small.
The easiest way is to start with the eyes. Enlarge the photo as much as possible and draw a line around it.
You don't need to be overly careful here. Just circle the shape. Outline the parts of the eye
and connect everything together. As a result, you should get a single grid.
08. Outline other parts of the face.
Separate nose, second eye. Use the zoom to quickly navigate through the photo.
09. Forget about unfinished lines.
During the stroke, you will have a lot of inconsistent lines. Throw them on for now.
Bringing each line tightly will distract you from the main task.
10. Part your hair.
When painting most portraits, parting the hair turns into a special exercise.
Try dividing your hair into separate large curls. They don't have to look perfect.
Just catch the direction of the curl and where it intersects with others.
11. We continue.
Yes, this is quite a painstaking job) Therefore, when you finish tracing everything, take a break!
The next part is even harder.
12. Connect the lines.
Now back to our unclosed lines. All of them need to be connected so that the color
didn't come out.
13. Polygonize!
The most fun part of the polygon portrait is the actual creation of the polygons. Starting again
from small objects, starts drawing triangles.
14. Balance of polygons.
Use different polygon sizes. Small for small objects like eyes. And more
for large parts. But keep a balance. Different polygon sizes will give more work
expressiveness.
15. Convert to Live Paint.
Congratulations! You have made the whole mesh. The hardest part is over. Now select everything except the background and
click Object > Live Paint > Make. Now you can paint the mesh with a color fill.
16. Coloring.
Zoom in on the photo's eye and select a color with the eyedropper. Fill the triangle with color.
And try not to hit the jar in the line! And learn hotkeys if you haven't already.
17. Remove the grid.
After you complete the coloring process, move the position of the stroke color (stroke) to
None position. Now check the whole picture and look for the polygons that you forgot to colorize.
18. Add your own taste!
That's all! Now you have a kickass polygonal portrait. Now you can have some
customize. Give it personality - chip off a couple of polygons, apply other effects.
More recently, a fashion has come to Runet for low poly stylization of portraits, photos of animals and other images. On this basis, a lot of lessons on creating such images have appeared on the network and still appear. Art in style low poly(polygonal portrait) helps to smooth out unpleasant little things in the photo and focus on color scheme and face profile.
What is Low Poly?
This term first appeared in English language in the world of 3D modeling. Low - low, Poly (Polygon) - polygon: that is, a low polygon, and in programs for working with 3D, this term refers to low-poly models used to save computer resources. A little later, someone adapted this idea for 2D images, it turned out pretty well, and the idea began to spread ...
How to make a low poly portrait. Ways to create a polygonal portrait
- In raster mode (via Adobe Photoshop )
- In vector mode (via Adobe Illustrator)
- In vector mode online
- In vector and raster mode through the application DMesh
Main difference bitmaps from vector is that vector images do not change in quality when their size is changed, while raster ones, on the contrary, lose much in quality. While creating vector portrait or another image in low poly style, you can print it even on a huge advertising banner.

Creating a Low Poly Image in Adobe Illustrator(video lesson in Russian)
Create a Low Poly Portrait Online
I want to warn you right away that in this way it will be possible to create only a semblance of a polygonal portrait, since everything is done in a semi-automatic mode. The fact is that a computer, unlike human eye cannot accurately recognize features human face, shadows, light, etc., in connection with which it arranges the polygons (parts of the Low Poly portrait) in a chaotic manner.
All this is done through the following website breatharian.eu/triangulator
We go to it and drag the image that we want to make in Low Poly style with the mouse
We perform the steps shown below. You can place the dots yourself or randomly. We recommend the first option. You can also reset the result if it turned out not very beautiful. The image is saved in SVG format, which can then be recoded into other formats.
As a result, when working online, the following images are obtained:
Program for creating a Low Poly portrait
There is also a fourth option for creating a polygonal portrait - using the application Dmesh. This method is similar to the previous one (creating a Low Poly portrait online). It's a bit more complicated as you have to download special program, but the result will be much better! You can download this app . The site has both a free version and a paid version with advanced functionality. Moreover, there are versions for Windows, For iMac and for iOS. Below is a video of the program.
Here is the result when running the application:
Which way to create a Low Poly portrait to use is up to you.
Good afternoon, today I will tell you how to create a polygonal portrait in adobe illustrator. Choose the right photo good quality, otherwise, you may have difficulty filling triangles.
So, for example, I'll take this photo
This photo has a poor resolution, but I don’t have a better one, so I’ll create a polygonal portrait from this photo.
We load the photo into illustrator and, for greater convenience, copy it to a new layer, so that in the future we can compare the finished portrait with the original photo.
It is best to start drawing a portrait from the eye area. When creating the first triangle, it will probably be filled with the default color by default. For more convenience, select the triangle and set the parameters: no fill, set the outline to 1 point. As you work, you will see the image you are working on.
Enlarge the photo - select the pen tool and draw the first triangle. Returning to the third point, you will see a circle icon, which means that this triangle will be converted into a closed path.
So, having received the first triangle, we begin to draw the next one, from the point of the edge of the previous triangle. If you hover over the edge of a drawn triangle to start drawing the next one, you will see a pen icon with a "-" sign, meaning that when you click with the mouse, you will delete a point in this triangle.
But we need to create a new triangle, and not remove the point in the already drawn one. To do this, we hold down the “shift” key and see how the pen has changed its value from the “-” sign to the “*” sign (asterisk) meaning that when you press the left mouse button, you will start drawing a new object.
We continue to draw triangles. As a result, we get a grid of triangles on top of the photo
By removing the visibility of the photo in layers, you get this result
Bring back the visibility of the photo and start painting over each triangle. To do this, you need to select the triangle, click on the "eyedropper" button and paint over the triangle, taking the appropriate color from the photo
If the photo is low resolution (like mine), then it is possible to see that the points of the triangles are separated from each other in some places. We fix this by making the triangle larger and selecting it. Select the white arrow in the toolbar (direct selection).
