Detailed Description

An example code below:

// Somewhere in your chode
ffw::GLProgram program;
ffw::GLShader vertShader;
ffw::GLShader fragShader;

// Initialization (run this only once)
try {
    // Compiles the shaders
    vertShader = ffw::GLShader(GL_VERTEX_SHADER, ...shader code here as string...);
    fragShader = ffw::GLShader(GL_FRAGMENT_SHADER, ...shader code here as string...);

    // Links the two shaders into one program
    program = ffw::GLProgram({ &vertShader, &fragShader });
} catch (ffw::GLException& e) {
    std::cerr << "Something went wrong: " << e.what() << std::endl;
}

// Rendering
while(true) {
    // Begin our shader program
    program.bind();

    // Bind VBOs, VAos, etc...
    // Bind uniforms, attributes...
    program.setUniformMatrix4fv(
        boxProgram.getUniformLocation("model"), &matrix[0], 1);
    
    // Draw the vertices using VBO
    program.drawArrays(GL_TRIANGLES, 0, 24);

    // Stops the shader program
    program.unbind();
}
