Creating a logical device

The logical device is one the most important objects created in our application. It represents real hardware, along with all the extensions and features enabled for it and all the queues requested from it:

The logical device allows us to perform almost all the work typically done in rendering applications, such as creating images and buffers, setting the pipeline state, or loading shaders. The most important ability it gives us is recording commands (such as issuing draw calls or dispatching computational work) and submitting them to queues, where they are executed and processed by the given hardware. After such execution, ...
