In this book, we have tried to do two things: give you a fundamental understanding of the tools you are using and put you into real-life situations in which you would be required to produce renderings of real-life projects.The approach was to go over tasks that an architectural illustration artist would typically find him- or herself in. The discussions and tutorials are limited to materials and lighting—essentially, what makes up mental ray. We have assumed that you already know how to create architectural models and leave it up to you to determine what software you feel the most comfortable using to create those models.
