GLFWwindow* window;
window = glfwCreateWindow(800, 600, "TrackballTest", NULL, NULL);
glfwMakeContextCurrent(window);
// You can set the Trackball camera to another position and give it a name
cam.setPosition(glm::vec4(0.0,0.0,10.0,1.0));
cam.setName("TrackballCam");
cam.setNearFar(0.01f, 100.0f);
// Set all InputMaps and set one InputMap active
iH.setAllInputMaps(cam);
iH.changeActiveInputMap("Trackball");
// Callback
glfwSetKeyCallback(window, key_callback);

// Shader

// Renderer

// Object
Teapot teapot;
teapot.loadBufferData();
// getting the start time
double startTime = glfwGetTime();
while (!glfwWindowShouldClose(window))
{

// You have to compute the delta time
cam.setSensitivity(glfwGetTime() - startTime);
startTime = glfwGetTime();
shader.bind();
// You have to send the uniform matrices of the Trackball camera to the shader
shader.sendMat4("viewMatrix", cam.getViewMatrix());
