3D modelling: basics



Polygonal: Digital 3D shapes made up of faces, created using vertices (Corner points)

NURBS: Non-Uniform Rational Bee Splines

Vertex: corners of a 3D shape

Extrusion: extending the shape to create a new shape

Sub-division: Dividing shape to gain more information on that shape.

Valence: Number of edges from a point

N-gon: A shape with 5 points or more, making the shape uneven and hard to work with.

Cartesian: Maya’s grid system


Q= General selection

W= Move tool



F= Focus on one shape

A= Focus on all objects

D= Move pivot point

3D modelling Industries


Gaming: Modelling characters, environments and objects in game

Geology: Used for simulating earthquakes and different landforms such as Deep-sea trenches.

Entertainment: Most blockbuster films and television shows use 3D modelling for CGI (Computer Graphic Imaging) to create artificial characters and environments in their film that they cannot use practical (non-digital) effects for.

Publishing: 3D is used in publishing to let publishers show environments or flora and fauna in their book that may be difficult to depict in their writing. Especially in fantasy books that contain environments that do not exist in real-life.

Different programmes used for 3D publishing include TurboCad, 3DCad, and Architect3D.


Autodesk Maya

Maya has 2 main file types

  1. .MA: Maya Askey
  2. .MB: Maya Binary


Magnet 1= Snap to grid


3D models: spaceship

A basic 3D space-ship

First of all, I created a small cube as the basis of my ship, then made 2 new cubes on either side of the first.

Using the extrude component tool, I manipulated the cubes on either side of the main cube, to look like wings, then, adding a new cube in front of this, I used the same tool to transform it into a trapeze shape to form the front.
