How is such an asymmetrical background made?

Question

Design

I am interested in how such a background is made as on paper (assembled from triangles of different sizes and at different angles):

Are there special plugins that allow you to make such a background, or is it done manually? What is the correct name for this technique? Tell me links to lessons where you can learn how to create background images of this type.

Answer 1

polygon design
low poly design
polygon design plugin
polygon abstract background tutorial
polygon abstract background
In general, search for these words, there are a lot of plugins and tutorials, now it's in trend.
And there is a way to remake photos. Or take some colored background and triangulate it) The programs are called Triangulators

I didn’t check this one specifically, but there are also a lot of them on the network.

Answer 2

The task of constructing such drawings is solved on the basis of Delaunay triangulation .
Here is another good free triangulation program - DMesh (Win/Mac/iOS).
