I was watching a video of hyper-realistic humans and I’m seeing the meshes they used to create the surface of a human’s face. I wonder how these meshes are created, picture follows:
In this case they used quadrilateral faces and do this thing, where they connect multiple orthogonal faces to go into the desired directions (marked in red). My question is: What is the logic behind this technique and where can I learn about surface to mesh algorithms like this.
My aim is to develop complex facades and have control over mesh-density and the direction of the mesh-edges (marked in green). In the following picture you can see the bands of mesh-faces:
I think this way of meshing would make a great looking facade.
