## Triangulation and Tesselation

In this chapter I’d like to discuss triangulation and tessellation, two related topics taken from the computational geometry branch of mathematics, which can be used to provide interesting useful insights about a set of spatial data. Discussion of these topics necessarily involves some mathematical theory, and may initially seem slightly abstract. However, once you've got your head around them you’ll see that tessellation and triangulation have plenty of practical spatial applications, and I'll show you just a few of these.

### The Importance of Triangles

Triangles are the most basic, and arguably the most useful, type of polygon. Because of their simplicity and the conciseness and efficiency with ...
