This is the example code for the OpenGL Programming Guide (Red Book), 9th Edition. It is mostly an import of code from previous editions with minor updates to match some of the descriptions in the latest edition of the book. We will be adding more samples and updating existing ones over time. Treat this as a live repository. Pull requests and issues are welcome. Go forth and fork!
We are using CMake as our build system. To build the samples, enter the "build" subdirectory and enter "cmake -G "{your generator here}" .." Project files or makefiles will be produced in the build subdirectory. We have tested Unix makefiles ("Unix Makefiles") and Visual Studio project files. Visual Studio 2013 ("Visual Studio 12") was used to develop most of the samples. An update to add support for 2015 will land shortly. Code should compile, but the templates for the project files are not in the repository at this time. Other compilers and IDEs should work, but we haven't tested them.
After building, there will be a large collection of executables in the bin directory. These are the example applications, which you can directly execute.
The media is now included with the git repository, and the samples should compile and run out-of-the box. Of course, make sure your OpenGL drivers are up to date and that your hardware is capable of running OpenGL 4.5. That's what this book is about. Some systems don't support OpenGL 4.5 and will therefore not run some of the samples. Trying to run such samples on a machine that doesn't have OpenGL 4.5 support will fail. For example, if a platform were limited to, say OpenGL 4.1, then the samples wouldn't work on that platform. Please don't file bugs about that either. Error checking in these applications is minimal. If you don't have media files or if your OpenGL drivers are out of date, they'll probably fail spectacularly.
Xcode project is already in xcodeProj directory. if you want create you own project file do as following:
- mkdir yourDir
- cd yourDir
- cmake -G Xcode .. your xcode project will be created in yourDir
Some files have been modified for MAC os environment, especially some header file. If you are interested in the modification adapted for Xcode, you can compare codes here with the original @ https://github.com/openglredbook/examples.git
Because my MAC only support OpenGL 4.1, but source @ https://github.com/openglredbook/examples.git is based on OpenGL 4.5, some API may crash or error. I have changed some API call from version 4.5 to 4.1 so that my MAC can run the demo, but not all demo is adapted for API 4.1.
