Splet06. okt. 2024 · The composition swapchain API provides a few different mechanisms to allow your application to practice proper synchronization of buffers it has presented. A buffer is said to be available if there are no outstanding presents that reference it, and it is currently not being displayed by the system. Otherwise, it is unavailable. SpletTutorial 2: Swap Chain – Integrating Vulkan with the OS Welcome to the second Vulkan tutorial. In the first tutorial, I discussed basic Vulkan setup: function loading, instance creation, choosing a physical device and queues, and logical device creation. I'm sure you now want to draw something! Unfortunately we must wait until the next part. Why?
