Building Quality Shaders for Unity®
Understand what shaders are and what they're used for: Shaders are often seen as mystical and difficult to develop, even by skilled programmers, artists, and developers from other game design disciplines. This book dispels that idea by building up your shader knowledge in stages, starting with fundamental shader mathematics and how shader development mindset differs from other types of art and programming, and slowly delves into topics such as vertex and fragment shaders, lighting, depth-based effects, texture mapping, and Shader Graph. This book presents each of these topics with a comprehensive breakdown, the required theory, and some practical applications for the techniques learned during each chapter. The HLSL (High Level Shading Language) code and Shader Graphs will be provided for each relevant section, as well as plenty of screenshots. By the end of this book, you will have a good understanding of the shader development pipeline and you will be fully equipped to start making your own aesthetic and performant shader effects for your own games! You Will Learn To • Use shaders across Unity's rendering pipelines • Write shaders and modify their behavior with C# scripting • Use Shader Graph for codeless development • Understand the important math behind shaders, particularly space transformations • Profile the performance of shaders to identify optimization targets.

Overcome the challenges and complexities involved in creating your own shaders with high-level realism using practical solutions, best practices, and the latest features of Unity 2021 Key Features Discover practical recipes for mastering post-processing effects and advanced shading techniques Learn the secrets of creating AAA quality shaders without writing long algorithms Create visually stunning effects for your games using Unity's VFX Graph Book DescriptionShaders enable you to create powerful visuals for your game projects. However, creating shaders for your games can be notoriously challenging with various factors such as complex mathematics standing in the way of attaining the level of realism you crave for your shaders. The Unity 2021 Shaders and Effects Cookbook helps you overcome that with a recipe-based approach to creating shaders using Unity. This fourth edition is updated and enhanced using Unity 2021 features and tools covering Unity's new way of creating particle effects with the VFX Graph. You'll learn how to use VFX Graph for advanced shader development. The book also features updated recipes for using Shader Graph to create 2D and 3D elements. You'll cover everything you need to know about vectors, how they can be used to construct lighting, and how to use textures to create complex effects without the heavy math. You'll also understand how to use the visual-based Shader Graph for creating shaders without any code. By the end of this Unity book, you'll have developed a set of shaders that you can use in your Unity 3D games and be able to accomplish new effects and address the performance needs of your Unity game development projects. So, let's get started!What you will learn Use physically based rendering to fit the aesthetic of your game Create spectacular effects for your games by testing the limits of what shaders can do Explore advanced shader techniques for your games with AAA quality Use Shader Graph to create 2D and 3D elements for your games without writing code Master the math and algorithms behind the commonly used lighting models Get to grips with the Post-Processing Stack to tweak the appearance of your game Who this book is for This book is for game developers who want to start creating their first shaders in Unity 2021 and take their game to a whole new level by adding professional post-processing effects. The book assumes intermediate-level knowledge of Unity.
Erstellung hochwertiger Shader für Unity®
Shader gelten oft als mystisch und schwer zu entwickeln, selbst für erfahrene Programmierer, Künstler und Entwickler aus anderen Bereichen des Spieldesigns. Dieses Buch räumt mit dieser Vorstellung auf, indem es Ihr Wissen über in Stufen aufbaut. Es beginnt mit grundlegenden Shader-Mathematiken, erklärt, wie sich die Denkweise der Shader-Entwicklung von anderen Arten von Kunst und Programmierung unterscheidet, und geht dann langsam auf Themen wie Vertex- und Fragment-Shader, Beleuchtung, Tiefenbasierte Effekte, Texture Mapping und Shader Graph ein. Jedes dieser Themen wird mit einer umfassenden Aufschlüsselung, der benötigten Theorie und einigen praktischen Anwendungen für die im jeweiligen Kapitel gelernten Techniken präsentiert. Der HLSL (High Level Shading Language)-Code und Shader Graphs werden für jeden relevanten Abschnitt bereitgestellt, ebenso wie zahlreiche Screenshots. Am Ende des Buches werden Sie ein gutes Verständnis für den Shader-Entwicklungsprozess haben und bestens gerüstet sein, um Ihre eigenen ästhetischen und leistungsstarken Shader-Effekte für Ihre Spiele zu erstellen! Was Sie in diesem Buch lernen Shaders in den Rendering-Pipelines von Unity zu verwenden Shader zu schreiben und ihr Verhalten mit C#-Skripting zu ändern Shader Graph für eine Entwicklung ohne Code zu nutzen Die wichtige Mathematik hinter Shadern zu verstehen, insbesondere Raumtransformationen Die Leistung von Shadern zu analysieren, um Optimierungspotenziale zu identifizieren Zielgruppen Dieses Buch richtet sich an Anfänger in der Shader-Entwicklung oder Leser, die den Schritt von Shader-Code zum Shader Graph machen möchten. Es enthält auch einen Abschnitt über Shader-Beispiele für diejenigen, die bereits die Grundlagen von Shadern kennen und nach spezifischen Anwendungsfällen suchen.
