I would like to thank several people for helping me through this project. In particular, Kevin Pulo for his invaluable help with many technical difficulties (such as the idea for the ``invalid positions'' solution for the visualisation in Section 2.3). Also, Dr Nicole Bordes, Ben Simons (colourbar), Daniel Mitchell (who suggested the use of OpenDX), Stephen Manos, Anita Hoving (for administrative support). Special thanks to my supervisor Dr C. Martijn de Sterke for helping me with the generation of some of the data used, and my co-supervisor Dr James Besley for useful suggestions.
This project was produced using the facilities provided by the Sydney Regional Scientific Visualisation Laboratory, 2001, as part of the Scientific Visualisation course.
