The 12 Best Free Low Poly Generators

0 Shares

Low poly generators can add a great deal of interest to your images. And when used as backgrounds, they help to give your website that elegant, yet retro feel.

This style came into vogue back when designers realized they could use bold and bright geometry to create patterns or images that could evoke a 3D look. But thanks to how simple low poly designs are, they don’t use a lot of storage and bandwidth.

This article provides an introduction to low poly images as well as links to the best free generators to create great backgrounds and other images with them.

Just interested in getting one of the low poly generators? Go straight to background or specialized generators!

Low Poly Image History

Low poly imagery goes all the way back to when computer animation began. Many of the techniques used in this form of animation date back to early 1940s when computers didn’t even have screens.

Decades down the line, computer animation became mainstream and widespread.

By the 1980s, 3D figures had started being built using polygon meshes which led to 3D video games. In turn, this led to the use of computer animation and 3D characters in movies such as Terminator 2.

Low poly was used in video games because of the fast rendering. You can think of low poly as a special kind of mosaic that uses polygonal shapes (triangles are by far the most common).

The key examples of this kind of design are a mesh of triangles constituting textures, typical computer background images, and even entire pictures where the images have geometrical figures connected to one another.

You can think of low poly as a special kind of mosaic that uses polygonal shapes with triangles being the most common..

While doing 3D rendering, designers achieve the desired effect of creating a realistic character by using more polygons in the image.

In web design, however, the exact opposite is true. The number of polygons used is reduced to an absolute minimum since the main idea here is that the triangular designs should be clearly visible.

Why Use Low Poly Generators and Art?

A designer often has to render 3D art if they want to display qualities such as lighting and animation. This used to take a lot of computer power and required expensive supercomputers to do.

Over the years, designers learned that in order to reduce the workload and therefore minimize the need for expensive supercomputers, simply eliminating the number of polygons within the meshes would work. That is what we now call “low poly.”

Even though today you can buy a laptop powerful enough to render advanced computer animation using millions of polygon counts per frame, low poly still thrives because it takes us back to a simpler time and help’s designers evoke a more retro look and feel.

Although you can always use photo editors such as GIMP or Photoshop to create images for your website, if you want to fill it with geometry then you will normally use low poly generators or background generators.

With that being said, here is a list of some of the best low poly generators online today.

Low Poly Background Generators

All of the following low poly generators are free. If you want even more power, both DMesh and HalftonePro have low-priced premium editions.

1. Trianglify

Trianglify is the one tool you need if you want to create low poly backgrounds as fast as possible…

Trianglify is a simple to use application that allows you to create low poly backgrounds in very little time. You can download them as PNG files.

The colors used are selected randomly and change with all new creations. You can easily control the size and variance of the shapes. Trianglify is the one tool you need if you want to create low poly backgrounds as fast as possible.

Trianglify generates a choice of 27 refined color schemes that are foolproof. However, if you don’t like any of them, then you can simply build your own color scheme with a 24-bit color picker offered within the program.

2. DMesh

The genius of DMesh is that it can easily turn pre-existing images into low poly files by simply overlaying the desired 3D triangle mesh over a 2D picture.

DMesh is actually designed with newbies in mind…

You can even auto-generate the points but if you want a more refined look, you are advised to create your own points.

Even though DMesh might look like an advanced background generator or image editing program, it is actually designed with newbies in mind. That is why you will find useful features such as automatic point generation which makes it very easy to use.

The free version of DMesh does not allow you to control the number of polygons used or the density of distribution. But by using the eraser tool you can easily reduce the number of triangles rendered into your image after the fact.

With DMesh, you can export your finished files in bitmap, Wavefront OBJ, or PDF formats.

3. HalftonePro

This is a vector-based polygon generator which has a wide variety of customization options that allow you to create hexagonal headers and crystalline covers. This, however, is not the simplest of tools.

HalftonePro allows you to create detailed gradients with each setting radically changing the image…

HalftonePro has a wide range of complexities underneath the surface which gives it the amazing qualities that almost every designer would admire.

With this tool, you can easily create detailed gradients with each setting radically changing the image and giving you more image processing capabilities.

While this is a wonderful addition, it does mean that you have to be very careful of the amount of tweaking you do so as to give you the perfect header background.

HalftonePro gives you virtually limitless combinations. But it also provides a resize tool, which means that you do not need to use any other image editors should you want to scale down your final image to the right size.

4. Delaunay Triangle Generator

Before we talk about this low poly generator, it is best to explain “Delaunay triangulation” in general.

Delaunay Triangle Generator gives you up to seven virtual light sources which greatly help by casting ambient light on to the canvas…

Delaunay triangulation is a mathematical function that defines a triangle based on an array of points. In this kind of design, none of the points are inside the circumcircle of the other triangles. This means that this design avoids acute angles as much as possible and as a result makes very wide and large shapes.

The Delaunay Triangle Generator is based on these principles. The tool gives you up to seven virtual light sources which greatly help by casting ambient light on the canvas. You can easily tweak the colors as well as their intensity.

Most important, however, you can change the number of polygons as well as their softness.

If you are looking to create backgrounds that have gorgeously luminescent patterns and generally elegant pictures, this is the tool for you.

5. Polyshaper

Polyshaper is a an easy to use but powerful low poly generator…

Polyshaper is a web application that creates a low poly image based upon a regular image. But it provides a great deal of control.

With Polyshaper, you can enter your own points (but you don’t have to). And with separate tools, you can add and delete extra triangles.

You can turn on and off border shapes as well as the fill. You can also change the opacity of these elements.

Additionally, Polyshaper has a lot of color manipulation tools that allow you to get your low poly image exactly the way you want it.

6. Triangulator Triangulation Image Generator

Triangulator is a very easy-to-use low poly generator…

Triangulator Triangulation Image Generator is a very easy-to-use tool. It doesn’t have many options, but it is great if you need a low poly image but you aren’t too concerned about its details.

Like many low poly generators, Triangulator starts with a base image and creates a low poly image from it. It has a default image you can use.

Triangulator offers 3 algorithms: Yape06 (with Laplacian and Mineigen controls), Yape (with radius control), and Fast Corners (with threshold control). Yape06 provides the most control and Fast Corners produces more typical low poly images.

You can also set the image size to whatever the base image is or 720p, 1080p, and 2160p.

Specialized Low Poly Generators

The tools in this section are more specialized than the ones above. Most of them are fun to use. But more than that, they are helpful to bloggers for various uses.

1. PolyGen

This is by far one of the best low poly generators available on mobile (you can find it in both the App Store and Play Store).

By far one of the best low poly generators available on mobile…

PolyGen is really built for personal use such as the creation of phone backgrounds and avatars. But it can be put to great use by designers who primarily work on the go and on their phones to generate images that fit perfectly for their mobile projects.

PolyGen is undoubtedly small, but that does not mean that it lacks in excellent content. It has a features list that goes toe to toe with any full-scale PC low poly generator on the market today. Additionally, it can be used to create beautiful design patterns or just to simplify pictures.

You would expect that a tool which was long a monopoly in the mobile low poly generator market would be a little lacking in some areas. Rest assured that this is not the case with PolyGen.

This tool does not sacrifice quality in the least bit. That is why it is the go-to low poly generation tool for mobile users and designers.

4. Poly Maker

Polymaker is powerful as well as fun to use…

Poly Maker is a surprisingly powerful tool for one that is so much fun to work with.

It is unusual in a lot of ways, but especially in terms of what it uses to create a low poly image: 4 user-selected points that are fit with a cubic Bézier curve. So you start any project by clicking 4 places on the screen. You will quickly learn how these points determine the final image.

Poly Maker has various ways to change the image. For example, you can set the number of steps used as well as the two-color scheme. There are many more settings as well.

You can also download the images in PNG form. If you want, you can display the SVG code. This code can be copied and pasted into a local file.

How to Choose the Right Low Poly Generator

Choosing the right low poly generator really boils down to your general design skills and what you want to achieve in the end. Designers who are more advanced in their career will be happy with highly complex tools such as HalftonePro while those who are just starting out might want to use DMesh or PolyGen.

What you want to do is find a tool that has the following qualities:

  • Easy to use
  • Gives you the most options when it comes to color scheme
  • Has the most settings without being too complicated
  • Allows you to export your finished work in your desired format
  • Has a wide support network online

Any of the above mentioned low poly generators meet these requirements but are not equally as easy to use, and this is where your experience and preference comes into play.

While it is always easier to download pre-made images, using any one of these low poly generators to create or modify your own is better since it adds a unique element to your website.

Use any one of these low poly generators to improve your blog or other projects!
