Introduction to Computer Graphics with Vulkan and C++: Setting Up the Window
lve::LveWindow (LVE = Little Vulkan Engine) is created to encapsulate window-related functionality. It uses the GLFW library for platform-agnostic window management.#define GLFW_INCLUDE_VULKAN is used to tell GLFW to include the necessary Vulkan headers.initWindow): A private helper function initWindow is created to handle the GLFW initialization process. It initializes GLFW, sets window hints (disabling OpenGL context creation and resizing), and creates the window using glfwCreateWindow.initWindow. The destructor cleans up by destroying the GLFW window and terminating GLFW.lve::FirstApp is created to manage the application. It contains an lve::LveWindow member, ensuring the window is created and destroyed along with the application object.main function creates an instance of FirstApp and calls its run method within a try-catch block (for potential future error handling).FirstApp::run function contains a while loop that continues as long as the window doesn't signal it should close (!window.shouldClose()). Inside the loop, glfwPollEvents() is called to process window events.shouldClose: The LveWindow::shouldClose() function uses glfwWindowShouldClose() to check if the user has requested the window to close (e.g., by clicking the close button).LveWindow are deleted to prevent accidental copying of the window object, which could lead to double deletion of the underlying GLFW window resource. This follows the RAII (Resource Acquisition Is Initialization) principle.
