Neither svLis nor this documentation could have been written without the help of those colleagues. Initially I would like to thank John Woodwark, who instigated geometric modelling at the University of Bath, and who was the first person in the world to apply the technique of recursive spatial division to geometric models--a technique which is at the heart of svLis. Some of the other ideas in svLis are his, and he has strongly influenced the way in which svLis has developed towards a software product. John has also been of considerable assistance with this documentation.
The other people who have helped with svLis are Gary Bayliss, Jakob Berchtold, David Eisenthal, Ralph Martin, Steve Parry-Barwick, Dan Pidcock, Richard Taylor, Irina Voiculescu, Andy Wallis, and Kevin Wise. They have all contributed ideas and pieces of code. Also, they have been most patient in reconciling the goal of developing svLis with their need to use it in their own research work. This early testing by experts has been a great incentive to robustness.
