Unity for Architectural Visualization

Book Description

For architects the walk-around 3D computer visualization is a fantastic marketing tool. This tutorial shows you how to use Unity to achieve modeling skills through step-by-step examples. You’ll find the acquired expertise invaluable.

  • Simple instructions to help you set up an interactive and real-time scene

  • Excellent tips on making your presentations attractive by creating interactive designs

  • Most important features of computer games covered, to develop compelling, interactive scenes for so-called “serious games”

  • In Detail

    Architects have always relied on drawings, renderings, and sometimes even movies to present their design concepts to clients, contractors, and other stakeholders. The accessibility of current game engines provides new and exciting possibilities to turn any design into an interactive model that anyone can experience at their own pace.

    "Unity for Architectural Visualization" explains how you can create compelling, real-time models from your 3D architectural project. Filled with practical tips and in-depth information, this book explains every step in the process, starting from the very basics up to custom scripts that will get you up to the next level.

    This book begins with a general overview of the Unity workflow for architectural models. You will start with a simple project that lets you walk around in your design using basic Unity tools and methods. You will then learn how to easily get convincing lightning effects on your scene. You will then set up a basic navigation system in your project, and not only this; you will also cover some tips and tricks to take navigation to the next level. You will quickly learn how to fine-tune the shaders and how to set up materials that are a bit more advanced. Even when you finish Unity for Architectural Visualization, this book will make scripting easier with reusable examples of scripts that can be applied in most projects. After reading this book, you will be comfortable enough to tackle new projects and develop your own.
