This chapter considers the problem of encoding essential information about a compact surface in terms of a finite amount of data that can be stored and manipulated by computer. If all we want is the topological type of a surface, the genus and the orientability are sufficient. But in many applications, we would like to have a rough version of the geometry, and yet we don’t have, or don’t care about, an exact geometric description of the surface. Using Morse theory, it is possible to assign a code, or schematic representation, to a surface. We consider three problems:
  1. (a)

    How to code a Morse function on a smooth manifold, and in particular on a surface.

  2. (b)

    How to code a surface using a Morse function defined on it.

  3. (c)

    How to reconstruct a surface if we know a coding of it.
