Description

The OpenGL Shading Language (GLSL) is a programming language used for customizing parts of the OpenGL graphics pipeline that were formerly fixed-function, and are executed directly on the GPU. It provides programmers with unprecedented flexibility for implementing effects and optimizations utilizing the power of modern GPUs. With version 4.0, the language has been further refined to provide programmers with greater flexibility, and additional features have been added such as an entirely new stage called the tessellation shader. The OpenGL Shading Language 4.0 Cookbook provides easy-to-follow examples that first walk you through the theory and background behind each technique then go on to provide and explain the GLSL and OpenGL code needed to implement it. Beginning level through to advanced techniques are presented including topics such as texturing, screen-space techniques, lighting, shading, tessellation shaders, geometry shaders, and shadows. The OpenGL Shading Language 4.0 Cookbook is a practical guide that takes you from the basics of programming with GLSL 4.0 and OpenGL 4.0, through basic lighting and shading techniques, to more advanced techniques and effects. It presents techniques for producing basic lighting and shading effects; examples that demonstrate how to make use of textures for a wide variety of effects and as part of other techniques; examples of screen-space techniques, shadowing, tessellation and geometry shaders, noise, and animation. The OpenGL Shading Language 4.0 Cookbook provides examples of modern shading techniques that can be used as a starting point for programmers to expand upon to produce modern, interactive, 3D computer graphics applications.

Who is this book for?

If you are an OpenGL programmer looking to use the modern features of GLSL 4.0 to create real-time, three-dimensional graphics, then this book is for you. 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.

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

This is a good book for people familiar with OpenGL but less familiar with the modern versions of OpenGL. This book is particularly useful for OSX users, as OSX requires either the OpenGL 2.1 Compatibility mode or a modern OpenGL 4.1 Core mode. The "Core" version removes a lot of deprecated but useful functions. On the other hand, Linux and Windows programmers tend to have the OpenGL compatibility profile (which allows you to mix and match legacy functions with new ones). I found the examples were well thought out. The chapters build on each other, but each project is useful in its own right, and nicely demonstrates how the chapter's topic can be used in a practical manner. I found this book a great follow-on to Philip Rideout's classic (but slightly dated) iPhone 3D book. Both demonstrate the tools of the trade with artistic and useful examples.

Really awesome book and incredibly good value. Makes a change to a lot of the really long OpenGL books because you can find the OpenGL nugget you're interested in learning about or using and read the section on that.My only problem with this book is that the formatting for the Table of Contents could be a LOT better for the Kindle version. Whilst all the hyperlinks will take you directly to wherever you need to go, because this book has a set format for each chapter, the sub-sections for each chapter are repeated over and over again which makes it hard to see what the actual chapter is about. For example,Title1ABC2ABC3ABCIt's hard to see the numbers for all the letters!

This book covers OpenGL Shading Language Core profile 4 and modern OpenGL usage. It does assume some familiarity with OpenGL and C++, which helps to cut down on a lot of introductory boilerplate. It's best to start reading from the beginning, as examples and recipes build on information from previous chapters and Wolff doesn't waste space repeating the same stuff over and over, which I really appreciated.All of the examples use the newer OpenGL APIs, and there is some basic background information on how to use them. I found this useful for people like me who have been using the fixed-function API for so long. The examples also use OpenGL Mathematics (GLM), an Open Source toolkit for working with OpenGL-style vectors and matrices. I had been unaware of this toolkit, and I'll most likely be switching to it for my next project. Wolff's style is short and to the point and keeps things moving along.The meat of the book are the recipes, covering a wide range of shading topics, including emulating the OpenGL 2.0 fixed function pipeline, image processing, soft shadows, synthetic texture generation, and particle systems. There is a lot of information here and it is well written, though it assumes the reader is not a complete novice. Be warned, this is NOT a book for beginners.I had a couple of minor issues with the book. Most of the examples use C++ and the STL but in a few cases Wolff falls back to using malloc/free for temporary buffers. All of the recipes are based on using geometry, and even in the image processing section it is assumed we'll be processing a 3D scene. It would be nice to have some examples focused entirely on doing 2D image processing of images directly.Those points are very minor though and in all I thought the book was exactly what I needed to bring my skills up to the most recent OpenGL and GLSL standards.

I got a request from PACKT to review an OpenGL book they've published. It looked like a fun thing to do, so I said okay.First off, this book is perfect for people who already know their way around OpenGL, but may not be too deep into shaders yet, and/or have some legacy bits in their engines.The book does walk you through setting up a shader based application, and explains what kinds of support libraries you're going to need (always managing to pick the "other" lib than the ones I've used - they like glew more than glee, for instance - but the libs they picked still work as advertised, so I'm not saying they're bad choises. Oddly, there's no mention of SDL or SFML though), but knowing how OpenGL generally works as well as how the math generally works is taken for granted.On the positive side you won't have to browse through hundred pages of basic matrix and vector math, or compilation basics, which I feel is a good thing.After the basics the book gets to the fun stuff, explaining lighting, texture use, screen space trickery (like bloom and deferred shading), geometry shaders and tesselation, practical shadows (i.e, shadow mapping and PCT filters, but doesn't waste pages on anything "more advanced"), noise and some particle tricks.All in all I think it's a rather good resource for anyone who wants to upgrade their OpenGL knowledge to more "modern OpenGL", dropping all legacy stuff, but it doesn't mean you don't still have to get your hands on the orange book.

I found David Wolff's book to be very helpful in learning the foundations of GLSL programming with OpenGL. There are some nice advance techniques covered in this book also. The coding style is good, and the available source code (located on github) was helpful.
