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.
##Compiling## The libraries reside in the common/ folder
- common/include - header files
- common/linux_i386 - 32-bit linux libraries
- common/linux_x86_64 - 64-bit 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
###Linux###
- install the GNU Compiler Collection - usually by installing a "build-essentials" package via the package manager on your distribution.
- open a terminal and cd to the demo of choice
64-bit systems:
make -f Makefile.linux64
32-bit systems:
make -f Makefile.linux32
###Apple OS X###
- install Clang or GNU compiler and tools - usually by installing XCode
- open a terminal and cd to the demo of choice
make -f Makefile.osx
###Windows with GCC###
I only provided 32-bit versions of the Makefile and libraries here. The 32-bit builds will run on all Windows machines - I use 32-bit builds on my 64-bit Windows. If you want to add a 64-bit build it's pretty easy to copy the 32-bit Makefile and change the folder. You will need to recompile GLFW, GLEW, AssImp, and Freetype though.
- install the GNU Compiler Collection - usually by installing the MinGW toolkit. http://www.mingw.org/
- open a console and cd to the demo of choice
make -f Makefile.win32 (may have been renamed to mingw-make32 or similar)
- copy the .dll files from the main folder to the demo folder
###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VS 2013 seems to work, but with 2015 you'll probably need to download a newer version of the libraries used to get around linking errors.
##Caveats##
- There are some lazy
assert(call_some_function())calls that will be wiped out if compiling in a release mode that removes asserts. Replace these with your ownif (!call_some_function()) { print error and do appropriate thing } - Code is directly copy-pasted from book sections. This means that there will be redundant OpenGL calls to bind 55D0 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 clutteringmain.cpp. This means thatgl_utils.cppis not necessarily the same in each demo, but is built up gradually.
##SDL2 Port##
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/
