About the Authors
Ilya Grinblat started to work 35 years ago as developer of control systems, and some
years later, he moved to the development of Computer Aided Design software. He was
a development manager of the architectural software ARC+, and was working in the
development of the 3D city software—a software for 3D editing and management of a 3D
printer. Last year, he was working in the development of simulators and the 3D GIS software.
He was using Ogre to develop Civil Simulate—a software for 3D modeling of roads and
driving simulation.
I would like to thank many people from Packt publishing.
I would also like to thank my wife Irena for giving me the time and support to
write this book.
Alex Peterson is a graphics enthusiast with a background in game programming. His work
with the Ogre engine is primarily due to programming a universe size game engine, a space
skybox creator called Spacescape, and most recently, mobile games. Though his current life
is filled with his family and running a business, he makes it a point be active musically and
spiritually. He aims to promote his faith in God through his work to serve others, whether it is
by fueling their creativity, entertaining them, or educating them. You can find Alex online at

I would like to thank my Father, my family, my wife Lydia, the Ogre
development team, Steve Streeting, the Ogre forum moderators, Sean
O'Neil, Chris, Ava Barneys, and all the kind people who have helped me be a
part of this work. Thank you.

About the Reviewers
Matthew Casperson has worked in the IT industry for nearly a decade in a variety of roles,
and is the author of Away3D 3.6 Essentials. In his spare time, he loves nothing more than to
experiment with the latest Web and multimedia technologies. Many of these experiments can
be found on Matthew's personal website at http://goo.gl/2Hgr.
Thomas Trocha found his passion for the world of computer programming in the mid
eighties, using one of the first home computers - TI99/4a. Since then, he has studied
computer science, and developed his knowledge in a wide spectrum of computer
technologies. Inspired by the great online 48h game coding competition "Ludum Dare", he
shifted to 3D game development, which finally ended up in him founding his own game
company ToMaGa.
