Practical Shader Development: Vertex and Fragment Shaders for Game Developers (pdf)

Description

The book also shows you how to apply that theory to create eye-popping visual effects. You’ll learn to profile and optimize those effects to make sure your projects keep running quickly with all their new visuals. You’ll learn good theory, good practices, and without getting bogged down in the math.
Author Kyle Halladay explains the fundamentals of shader development through simple examples and hands-on experiments. He teaches you how to find performance issues in shaders you are using and then how to fix them. Kyle explains (and contrasts) how to use the knowledge learned from this book in three of the most popular game engines today.

What You’ll Learn

• Understand what shaders are and how they work
• Get up to speed on the nuts and bolts of writing vertex and fragment shaders
• Utilize color blending and know how blend equations work
• Know the coordinate spaces used when rendering real-time computer graphics
• Use simple math to animate characters, simulate lights, and create a wide variety of visual effects
• Find and fix performance problems in shaders
• See how three popular game engines (Unity, UE4, Godot) handle shaders

Who This Book Is For

Programmers who are interested in writing their own shaders but do not know where to start, anyone who has ever seen shader code on a forum and wished they knew how to modify it just a little bit to fit into their own projects, and game developers who are tired of using the default shaders found in the game engines they are using. The book is especially useful for those who have been put off by existing shader tutorials which introduce complex math and graphics theory before ever getting something on the screen.
