An outline is an incredibly useful tool in computer graphics. It provides enough information to fill in text, make procedural generated shapes, or fill in user drawn areas during run-time of a content creation application.

In Part 1 we talked about adding a point grid to the area inside a curve. The math could also be used to determine if a group of objects or characters fell inside a lasso like tool commonly found in CAD or paint applications. What if we wanted to build a surface from a point grid inside of an outline?

In Part 1 and Part 2 a mesh was created from a user drawn outline, however it's not very useful without graphics to go with it. This article focuses on setting up the UVs and Vertex Colors of a mesh from outline and then further using that data for procedurally generated content and shaders.
