This was the project my team an I had to do.

Let me explain what is going on here. The upper picture is an original 3D model my teammate did and which we used. It has 3000 faces(triangles).

The lower pic is the same model but the amount of triangles was simplified to 2000. As you can see the deformation is minimal.

All this was achieved by creating an agent(an autonomous program capable of communication) at each vertex. Then all these guys talk with each other and decide were to simplify the model.

Its actually quite more difficult than that but you get the basic idea. This kind of program could be used when different LOD models were needed for videogames or other things.


Note: This was made in Python, the model was an .obj and I made all the mathematic functions.
