John M. Blain has become a recognised expert in Blender having six successful prior editions of The Complete Guide to Blender Graphics to date. John became enthused with Blender on retirement from a career in Mechanical Engineering. The Complete Guide to Blender Graphics originated from personal notes compiled in the course of self learning. The notes were recognised as an ideal instruction source by Neal Hirsig, Senior Lecturer (Retired) at Tufts University. Neal encouraged publication of the First Edition and in doing so is deserving of the author's gratitude. Gratitude must also be extended to the author's wife Helen for her continuing encouragement and patience as new editions of the book are compiled.
