This book has been neither a labor of love nor a life's work. Being a Technical Writer by trade, documenting what I know is almost impossible to avoid. After being asked on several occasions if I could recommend a good book on UPK/OnDemand, and always having to reply that there simply weren't any books, good or bad, I decided to write my own.
This book is a distillation of five years' experience with UPK and OnDemand, and of teaching it to other developers.
I have seen many poor examples of simulations created using UPK or OnDemand, due primarily to a lack of knowledge on the part of the developers of the capabilities of UPK. My sole intention with this book is to show developers that it is not difficult to create truly impressive training simulations, with the correct knowledge and just a little effort.
I would like to thank the staff at Packt for their support, my long-standing client, ExxonMobil, for giving me the opportunity to learn so much about UPK and OnDemand, and the extremely knowledgeable Sjoerd De Vries, for doing such a great job on the technical review. I would also like to thank Seigun Kosabayashi and Yuki Iida for the Japanese texts, and Marc Wilms for the (petit) French.
