What are the fundamental
principles behind the creation of virtual 3D space? Describe and explain 3D
geometry.
How 3D Geometry works
3D geometry is similar to 2D geometry with the addition of a third axis in order to give volume and depth to shapes.
Geometry and Polygons
The most basic object in mesh modeling is a vertex. A vertex is a point in a 3D space. When two vertices connect with a line it becomes an edge. Three vertices connected by three edges becomes a triangle this is the simplest polygon to make. More complex polygons can be created by adding more points to a shape, creating squares, pentagons and such.

Primitives
Primitives are basic shapes which can be used and put together with points to create a polygon object, such as the rabbit above using the triangle planar alone
