Hi there,
I'm wondering how one can take care of multiply monitors in LWJGL 3 while also making sure the resolution and DPI settings are correct
as I've got a 24" FHD monitor and a 15" WQHD monitor and want to be able to launch the application on a specified monitor depending
whether it is connected or not, but also making sure everything looks the same size.
Note: It should work regardless of fullscreen mode or not (or what is left of fullscreen mode in Win10 1803
)
That's the code I've got in place currently:
// Create the window
this.window = glfwCreateWindow(this.width, this.height, this.title, NULL, NULL);
if(this.window == NULL) {
glfwTerminate();
glfwSetErrorCallback(null).free();
throw new RuntimeException("Failed to create the GLFW window");
}
// Get the thread stack and push a new frame
try(MemoryStack stack = stackPush()) { // thread-local lookup
IntBuffer pWidth = stack.mallocInt(1); // int* ; ip instance eliminated
IntBuffer pHeight = stack.mallocInt(1); // int* ; ip instance eliminated
// Get the window size passed to glfwCreateWindow
glfwGetWindowSize(this.window, pWidth, pHeight);
// Get the resolution of the primary monitor
GLFWVidMode vidmode = glfwGetVideoMode(glfwGetPrimaryMonitor());
// Center the window
glfwSetWindowPos(this.window,
(vidmode.width() - pWidth.get(0)) / 2,
(vidmode.height() - pHeight.get(0)) / 2
);
} // the stack frame is popped automatically
// Make the OpenGL context current
glfwMakeContextCurrent(this.window);
GL.createCapabilities();
glfwShowWindow(this.window);
I don't know if this is relevant to this question, but I'm using OpenGL 4.6.
Thx in advance.

Note that, when KAIHH writes that calling glDraw* is expensive, it also means calling gl* is expensive. When you update data in the gpu's memory, it's expensive.
Why do you update the transform in every frame? Also, why do you even create a new one in every frame? Once data in the GPU's memory, it should only be updated when it was really changed. Here is my rendering logic. Note that, updateBatchDataInGPU gets called ONLY if anything was changed.
