# Topology and Edgeflow

Topology
This falls into the realm of geometry and uses vertices, edges and faces to make a three dimensional model.

Polygon
A polygon is a shape that is used in topology to create a flat surface.

NURBS
This stands for non uniform rational B spline, and it helps you create a smooth surface using a low number of polygons.

NURMS
This stands for non uniform rational mesh smoothing and it uses algorithms to make smooth surfaces from 3D objects.

Vertex
This is a point (basically a dot, don’t let them confuse you) that exists in 3D space (a dot), and in between two dots you get an edge (guess what comes next).

Edges
This is a straight line that joins up two dots (vertices).

Faces
Faces are the solid surfaces that fill in the space between three or more connected vertices.

Edge flow
Edge flow is where you use curves to create an object. You have to use more polygons and define their shape more so that they do not look odd or pointy. http://www.cgmascot.com/design/surface-flow-matters/ (March 8 2010)
