Task 3 - Geometric Theory

Geometric theory is used in games to model characters and environment. An initial mesh is used to give a basic shape to an object that is later built upon with textures. the mesh consists of various 2D polygonal shapes, each polygon has Verticies, Edges and a face. In the creation of a polygon 2 verticies are connected together by a line creating the first edge. When another vertice is added a face is formed. This is a triangle but another vertice could be added to turn it into a quad. When creating character meshes tri's are used to create free flowing movement that looks smooth. Also when creating a mesh for a character all of the edges have to be connected do that the model can be composed entirely of 2D polygons.

Withing these models the user is able to use rigging to further enhance the models, this adds bones which the user can manipulate to create better animations.
