OpenGL Examples

This project uses premake to generate build files for linux or windows that link against SDL2 and OpenGL to run separate examples of OpenGL code. There is a set of core files that contain some OpenGL wrappers and a main file that runs a state machine inside of a game loop. In each example there is a state class that is set in the state machine at the start and has access to all of SDL2, SDL2_image, SDL2_ttf, SDL2_mixer, GLM, and OpenGL.

Building

Linux

git clone --recursive https://github.com/matthewjberger/opengl_examples.git
cd opengl_examples
./premake5 gmake
cd build
make
# Navigate to desired demo's output directory and run the corresponding executable

To build specific examples only, add or remove lines in the premake5.lua file that say:

create_example("projectName")

in the generate() function at the top of the file and then run premake again.

Windows

Download the source and header files for all of SDL2, SDL2_image, SDL2_ttf, and SDL2_mixer and set an environment variable called SDL2_PATH to point to the root folder. The SDL2 folder structure should look like this:

SDL2
└───include
│      
└───lib
    └─── x64
    └─── x86

Place all of the include files from SDL2_image, SDL2_ttf, and SDL2_mixer in the main SDL2 include directory above, and all of their library files in the lib/x86 and lib/64 folders above.

Then, download GLM and set an environment variable called GLM_PATH to point to the root folder. It should look like this:

glm
└───glm
└─── (other folders that come with glm)

Visual Studio 2015 is recommended if building on windows.
