Each chapter with major demonstration code has a corresponding demo here. There is also an example of code for Hello Triangle for OpenGL 2.1 for reference.
Each demo has easy-to-read Makefiles for Linux, OS X, and 32-bit Windows.
There are also Visual Studio projects, but you may have to download newer
versions of the libraries in the
common/ folder to match your version of VS.
This code is some years old now and builds may fall out of date. I try to maintain this so that it functions but be aware that Makefiles and build details may differ slightly from book text for this reason. If you have a [tidy] CMake setup or updated build feel free to submit a pull request here.
The libraries depended on reside in the common/ folder
common/include- Header files.
common/linux_i386- 32-bit GNU/Linux libraries.
common/linux_x86_64- 64-bit GNU/Linux libraries.
common/msvc110- 32-bit Windows Visual Studio libraries.
common/osx_64- 64-bit Apple OS X libraries.
common/win32- 32-bit Windows GCC (MinGW) libraries.
common/win64_gcc- 64-bit Windows GCC (MinGW-w64) libraries.
- Install a C and C++ compiler - usually by installing a "build-essential" bundle package via the package manager on your distribution:
sudo apt-get install build-essential
- Install the GLFW3 and FreeType libraries:
sudo apt-get install libglfw3-dev sudo apt-get install libfreetype6-dev
- Open a terminal and cd to the demo of choice, then
make -f Makefile.linux64
make -f Makefile.linux32
Apple OS X
- Install Clang or GNU compiler and tools - usually by installing Apple XCode through the App Store. It's free.
- Open a terminal and
cdto the demo of choice:
make -f Makefile.osx
Windows with GCC
If you have trouble linking supporting libraries you may need to recompile GLFW, GLEW, AssImp, and Freetype.
Install the GNU Compiler Collection - usually by installing MinGW (32-bit or the 64-bit alternative).
Open a console and
cdto the demo of choice.
make -f Makefile.win32(MinGW may have renamed
Copy the .dll files from the main folder to the demo folder
make -f Makefile.win64for the 64-bit build.
Windows with Visual Studio
I provided some Visual Studio 2012 project files. You can find an overarching solution file in the main folder. This should convert well to most versions of Visual Studio. I used 32-bit versions of the libraries, but there's no reason that you can't add 64-bit versions if you prefer.
VS 2013 seems to work, but with 2015+ you'll probably need to download a newer version of the supporting libraries used to get around linking errors.
- Code is directly copy-pasted from book sections. This means that there will be redundant OpenGL calls to bind things etc. but I think it's easier to follow along like this.
- Code explained in prior examples is moved to a file called
gl_utils.cppto avoid cluttering
main.cpp. This means that
gl_utils.cppis not necessarily the same in each demo, but is built up gradually.
Dr Aidan Delaney at the University of Brighton has made an SDL2 port (as an alternative to using GLFW), which you can find on GitHub https://github.com/AidanDelaney/antons_opengl_tutorials_book/
