Using Vulkan descriptor sets

A descriptor set object is an object that holds a set of descriptors. Think of each descriptor as a handle or a pointer to a resource. We can think of a descriptor set as everything that is "external" to the graphics pipeline or as a resource set. Also, the descriptor set is the only way to specify which textures and buffers can be used by the shader modules in the pipeline. The Vulkan API does not allow you to bind individual resources in shaders; they must be grouped into sets, and only a limited number of descriptor sets can be bound to a given pipeline. This design decision was mostly due to the limitations of some legacy hardware, which must be able to run Vulkan applications. In the next few chapters, we will learn how to partially overcome this constraint on modern hardware with Vulkan 1.2.

Now, let's learn how to work with descriptor sets in Vulkan.

Descriptor sets cannot be created directly. They must come...
