Creating Your First Shader

In this chapter, you will learn about the following recipes:

Creating a basic Standard Shader
Adding properties to a shader
Using properties in a Surface Shader

Key benefits

• Master shader programming through easy-to-follow examples

• Create stunning visual effects that can be used in 3D games

Description

Since their introduction to Unity, shaders have been seen as notoriously difficult to understand and implement in games. Complex mathematics has always stood in the way of creating your own shaders and attaining the level of realism you crave. Unity 2018 Shaders and Effects Cookbook changes that by giving you a recipe-based guide to creating shaders using Unity. It will show you everything you need to know about vectors, how lighting is constructed with them, and how textures are used to create complex effects without the heavy math. This book starts by teaching you how to use shaders without writing code with the post-processing stack. Then, you’ll learn how to write shaders from scratch, build up essential lighting, and finish by creating stunning screen effects just like those in high-quality 3D and mobile games. You'll discover techniques, such as normal mapping, image-based lighting, and animating your models inside a shader. We'll explore how to use physically based rendering to treat light the way it behaves in the real world. At the end, we’ll even look at Unity 2018’s new Shader Graph system. With this book, what seems like a dark art today will be second nature by tomorrow.

What you will learn

• Understand physically based rendering to fit the aesthetic of your game

• Write shaders from scratch in ShaderLab and HLSL/Cg

• Combine shader programming with interactive scripts to add life to your materials

• Design efficient shaders for mobile platforms without sacrificing their realism

• Use state-of-the-art techniques, such as volumetric explosions and fur shading

• Master the math and algorithms behind the most used lighting models

• Understand how shader models have evolved and how you can create your own

Great book, for those of you looking to learn some shader programming and are like me where you dont know where to start then this book is for you, i like how it takes you through set up and also provides demo materials which you can use as a guide or if you get stuck

I'm a professional web developer who's been into game programming for some time. Most Unity books cover 3D objects manipulation, game dynamics, etc. but they rarely touch on shaders' internals. Things like screen effects, different lighting types, liquids, fur, explosions - all seem like some kind of magic, written in a language with weird syntax and semantics that only few people understand.I've been trying to follow YouTube tutorials on writing shaders, reading blogs and articles, but always felt like I only understand a tiny piece of the puzzle. I was missing a holistic view and I couldn't find a good resource which would cover everything.This book is exactly what I've been looking for. It moves fast - reader is treated as a professional who doesn't need hundreds of examples for one topic - but it's also thorough. When you use a variable type, it tells you what other types there are and where to read about them more. It covers every topic I wanted to learn about plus some more. After reading the first few chapters I was already writing my own shaders, even coming up myself with ideas that were actually covered later in the book.The only thing that some readers may not like at first is the format of chapters. They follow this scenario: setting up a project, writing all of the code, running it, and then the explanation of what's going on. I'm personally more used to story-type tutorials where concepts are eased into. But very quickly I realised the potential of the approach this book takes. Every chapter is an entity of its own, allowing you to quickly come back to a specific topic when you need it, and gives you everything you need to see the concept in action.If you're a non-beginner software developer who wants to holistically understand shaders and write your own, this book is definitely worth reading.

例を示して動作を示す説明スタイルは、エントリーとしてとても解り易いです。残な点として、updateが最新に対応しきれていない点があり、ちょっと戸惑う点がある事です。まだunityで開発中の機能を説明しているので、タイムリーな更新が期待されます。

It’s a decent primer if you’ve never worked with shader code before. The author does a decent job explaining the fundamentals of writing shader code. However for the price of the book and its subject, its pretty dissapointing that the images are low quality and in black and white. Furthermore getting the source code to follow along with the recipes is a pain. The publishers website provides confusing and inaccurate instructions. If you’re tired of reading blog posts and online tutorials then this book might be worth it for you.

シェーダーやポストプロセスの良い本だとは思うのですが、グラフィックスを扱う本なのにまさかのモノクロです。カラーページは一切ありません。それと当然ながら英語のみなので、注意してください。
