Introduction to 3 Dimensional graphics

Representing 3 dimensions on a flat piece of paper is a very important skill for designers enabling them to communicate their ideas to other people. This is especially useful when showing your design to non designers such as managers and marketing personnel.

There are several tried and tested 3 Dimensional drawing systems used to produce a realistic representation of an object. Some techniques such as isometric are based on mathematical systems, others a try to convey a larger degree of realism by applying perspective to the drawing. Amongst the methods covered in this tutorial are oblique, isometric, axonometric, and perspective drawing techniques.

Oblique

Isometric

• Drawing a box in isometric.
• Drawing shapes other than cubes
• Drawing circles in isometric

Axonometric

Drawing 'holes' and cavities in objects

Perspective

• One Point Perspective
• Constructing a box in one point perspective
• Two point perspective
• Constructing circles in perspective
• Drawing Cylinders in perspective
• Constructing a grid (1)
• Constructing a grid (2)
• Using a grid
• Three point perspective
