Non-Euclidean surface growth

Non-Euclidean surface growth is the idea that the surface of something can change in ways that are not straight and flat, like a square or a triangle. Instead, the surface can be made up of curves and shapes that are more complicated. This is important when talking about things like computers and computer graphics, which often use non-Euclidean surfaces to create designs that look more 3-dimensional.
