A base openGL application written in C++ that sets you up for GLSL shader development in your machine. It is set up especially for fragment shader implementations such as the ones available at Shader Toy.
All the libraries are statically referenced and included in this repository for ease of use.
- Make sure you have the latest legacy drivers installed for you graphics card.
Install the following dependencies on your machine:
SDL2 - Cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D
sudo apt-get install libsdl2-dev
GLEW - OpenGL extension manager
sudo apt-get install libglew-dev
If you are using Visual Studio Code, it is as simple as pressing Ctrl + Shift + B to run the compilation and run tasks consecutively.
To compile:
g++ -g \*.cpp -I include/ -Llib -lGLEW -lSDL2main -lSDL2 -o main.cpp.out -lOpenGL
To run:
./main.cpp.out
In order to build this base application on windows you need to first move the files in the dlls directory to the root folder of the application.
You also need to install the mingw compiler in your machine and set its bin folder path on the global environment PATH variable.
You are now ready to compile and run the application. If you are using Visual Studio Code, there is already a task available that compiles and runs the code consecutively if you press the Ctrl + Shift + B key combination inside VScode.
If you are using another code editor, please refer to the next commands (assuming you are running windows powershell):
To compile:
g++ -g \*.cpp -I include\\ -Llib -lglew32s -lSDL2main -lSDL2 -o main.cpp.exe -lopengl32
To run:
.\\main.cpp.exe
If a windows opens up flashing between blue and purple color you know it is working.
