Rendering in SketchUp: From Modeling to Presentation for Architecture, Landscape Architecture and Interior Design

Digital Rendering and Photorealism

The term photorealism originally described a genre of oil painting in which the painter proceeds from a photograph rather than from direct observation and then produces a meticulously painted image that appears “photographic” in its realistic depiction of detail.

Computer rendering is the act of simulating the play of light on a 3D model. Virtual light reflects from the model surfaces, allowing them to take on the appearance of real-world objects and materials. The goal is to create images that look like photographs (Fig. 1.7 and Fig. 1.8).

This book will teach you how to create renderings with photorealistic qualities. By applying the methods taught here, you will be able to generate images that appear richer and more realistic than non-rendered images exported directly from SketchUp. Don’t expect expert results immediately, though. Most users have to work through a learning curve, and their first attempts can range from non-photorealistic to photorealistic (Fig. 1.9 and Fig. 1.10). To generate more realistic images, you’ll need to practice the concepts outlined in this book with diligence and repetition. The more effort you put in, the better your results and the faster ...
