Task 3: Geometric Theory

A 3D model is a mathematical representation of a shape in 3D space. Spheres, cubes, and cylinders are the examples of basic 3D models but can used to create even more complex ones.

There are two main types of 3D models used in the medias, them being NURBS surfaces and polygonal models. NURBS (Non-Uniform Rational B-Spline) surfaces are created using bezier
curves. They are also very mathematically accurate which is why they are commonly used in modelling for the engineering and automotive industries. Polygonal models are made up of vertices, edges, and faces. Polygonal models are commonly used in modelling and are used to create more complex and complicated shapes/objects. Polygonal models aren't too difficult to manipulate or morph which is why they are commonly used. When morphing a polygonal model, you must do it bit by bit which can take a lot of time and work. 

The 3 dimensional space in which games and software like Maya is based on the Cartesian coordinate system. This is essentially a map for the positions of the points of the 3D objects. This system was developed by the French philosopher, mathematician, and scientist, Rene Descartes. The system space uses 3 different axes: width (x), height (y), and depth (z).
