abstract

This document presents research into the three dimensional digitisation of physical objects. We also present a possible implementation of such a system. The research was been divided into two separate categories: digitisation through a hardware based procedure (such as a laser scan) and digitisation through a more software orientated approach. After examining the various techniques available to the digital artist, a possible approach is described for simple geometry reconstruction in the digital domain using stereo image pairs and a calculation of disparity. While this is arguably not the most effective method of three-dimensional digitisation, improvements and extensions are suggested before conclusions are drawn.
Although examples and explanations will naturally gravitate towards the film/special effects industry (as this is the author’s current area of study) the concept of digitisation will be linked to other areas where computer graphics are of use. Furthermore, while the term computer generated imagery is generally associated with such examples as Toy Story, Shrek and blockbuster special effects, it is used here in its more accurate meaning – any image that has been created using a computer, for any purpose.
