Overview of this book

OpenGL is a fully functional, cross-platform API widely adopted across the industry for 2D and 3D graphics development. It is mainly used for game development and applications, but is equally popular in a vast variety of additional sectors. This practical course will help you gain proficiency with OpenGL and build compelling graphics for your games and applications. OpenGL Development Cookbook – This is your go-to guide to learn graphical programming techniques and implement 3D animations with OpenGL. This straight-talking Cookbook is perfect for intermediate C++ programmers who want to exploit the full potential of OpenGL. Full of practical techniques for implementing amazing computer graphics and visualizations using OpenGL. OpenGL 4.0 Shading Language Cookbook, Second Edition – With Version 4, the language has been further refined to provide programmers with greater power and flexibility, with new stages such as tessellation and compute. OpenGL Shading Language 4 Cookbook is a practical guide that takes you from the fundamentals of programming with modern GLSL and OpenGL, through to advanced techniques. OpenGL Data Visualization Cookbook - This easy-to-follow, comprehensive Cookbook shows readers how to create a variety of real-time, interactive data visualization tools. Each topic is explained in a step-by-step format. A range of hot topics is included, including stereoscopic 3D rendering and data visualization on mobile/wearable platforms. By the end of this guide, you will be equipped with the essential skills to develop a wide range of impressive OpenGL-based applications for your unique data visualization needs. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products, OpenGL Development Cookbook by Muhammad Mobeen Movania, OpenGL 4.0 Shading Language Cookbook, Second Edition by David Wolff, OpenGL Data Visualization Cookbook by Raymond C.

Module 1:

The module assumes that the reader has basic knowledge of using the OpenGL API. The example code distributed with this module contains Visual Studio 2010 Professional version project files. In order to build the source code, you will need freeglut, GLEW, GLM, and SOIL libraries. The code has been tested on a Windows 7 platform with an NVIDIA graphics card and the following versions of libraries:

We recommend using the latest version of these libraries. The code should compile and build fine with the latest libraries.

Module 2 :

The recipes in this module use some of the latest and greatest features in OpenGL 4.x. Therefore, in order to implement them, you’ll need graphics hardware (graphics card or onboard GPU) and drivers that support at least OpenGL 4.3. If you’re unsure about what version of OpenGL your setup can support, there are a number of utilities available for determining this information. One option is GLview from Realtech VR, available at: http://www.realtech-vr.com/glview/. If you’re running Windows or Linux, drivers are readily available for most modern hardware. However, if you’re using MacOS X, unfortunately, you may need to wait. As of this writing, the latest version of MacOS X (10.9 Mavericks) only supports OpenGL 4.1.

Once you’ve verified that you have the required OpenGL drivers, you’ll also need the following:

  • A C++ compiler. On Linux, the GNU Compiler Collection (gcc, g++, and so on) may already be available, and if not, it should be available through your distribution’s package manager. On Windows, Microsoft Visual Studio will work fine, but if you don’t have a copy, then the MinGW compiler (available from http://mingw.org/) is a good option.
  • The GLFW library Version 3.0 or later, available from http://www.glfw.org/. This library provides OpenGL context creation, window support, and support for user input events.
  • The GLM library Version 0.9.4 or later, available from http://glm.g-truc.net/. This provides mathematics support with classes for matrices, vectors, common transformations, noise functions, and much more.

Module 3:

This module supports a wide range of platforms and open source libraries, ranging from Windows, Mac OS X, or Linux-based desktop applications to portable Android-based mobile applications. You will need a basic understanding of C/C++ programming and background in basic linear algebra for geometric models.

The following are the requirements for chapters 1 to 3:
