How to Render: The Fundamentals of Light, Shadow and Reflectivity (Paperback)

This book is about the fundamentals of light, shadow and reflectivity; the focus is firmly on helping to improve visual understanding of the world around and on techniques for representing that world. Rendering is the next step after drawing to communicate ideas more clearly. Building on what Scott Robertson and Thomas Bertling wrote about in How To Draw: Drawing and Sketching Objects and Environments from Your Imagination, this book shares everything the two experts know about how to render light, shadow and reflective surfaces. This book is divided into two major sections: the first explains the physics of light and shadow. One will learn how to construct proper shadows in perspective and how to apply the correct values to those surfaces. The second section focuses on the physics of reflectivity and how to render a wide range of materials utilizing this knowledge. Throughout the book, two icons appear that indicate either “observation” or “action.” This means the page or section is about observing reality or taking action by applying the knowledge and following the steps in creating your own work. Similar to our previous book, How To Draw, this book contains links to free online rendering tutorials that can be accessed via the URL list or through the H2Re app.

這本書主要介紹光線、陰影和反射的基礎知識，重點在於幫助提升對周圍世界的視覺理解以及表現這個世界的技巧。渲染是繪畫後的下一步，用於更清晰地傳達想法。在《如何繪畫：從你的想像中繪畫和素描物體和環境》一書中，史考特·羅伯森（Scott Robertson）和托馬斯·伯特林（Thomas Bertling）所著的內容，本書分享了這兩位專家對於如何渲染光線、陰影和反射表面的所有知識。本書分為兩個主要部分：第一部分解釋了光線和陰影的物理學。讀者將學習如何在透視中構建正確的陰影，以及如何對這些表面應用正確的值。第二部分則聚焦於反射的物理學，以及如何利用這些知識渲染各種材料。在整本書中，會出現兩個圖示，分別表示「觀察」和「行動」。這意味著該頁或該部分是關於觀察現實或應用知識並按照步驟創作自己的作品。與我們之前的書《如何繪畫》一樣，本書包含了連結到免費在線渲染教程的URL列表，或者可以通過H2Re應用程式訪問。
