OpenGL 4 Shading Language Cookbook, Second Edition

Acquiring the skills of OpenGL Shading Language is so much easier with this cookbook. You ll be creating graphics rather than learning theory, gaining a high level of capability in modern 3D programming along the way.

Key Features

• Discover simple and advanced techniques for leveraging modern OpenGL and GLSL
• Learn how to use the newest features of GLSL including compute shaders, geometry, and tessellation shaders
• Get to grips with a wide range of techniques for implementing shadows using shadow maps, shadow volumes, and more
• Clear, easy-to-follow examples with detailed explanations and full, cross-platform source code available from GitHub

Book Description

What you will learn

• Compile, debug, and communicate with shader programs
• Use new features of GLSL 4 such as subroutines, sampler objects, and uniform blocks
• Implement core lighting and shading techniques such as diffuse and specular shading, per-fragment shading, and spotlights
• Use textures for a variety of effects including cube maps for reflection or refraction
• Implement screen-space techniques such as HDR, bloom, blur filters, order-independent transparency, and deferred shading
• Utilize noise in shaders
• Use shaders for animation
• Make use of compute shaders for physics, animation, and general computing
• Learn how to use new OpenGL features such as shader storage buffer objects, and image load/store

Who this book is for

This book is for OpenGL programmers looking to use the modern features of GLSL 4 to create real-time, three-dimensional graphics. Familiarity with OpenGL programming, along with the typical 3D coordinate systems, projections, and transformations is assumed. It can also be useful for experienced GLSL programmers who are looking to implement the techniques that are presented here.
