AI Description

This C++ component is designed to manage descriptor heaps in a DirectX 12 graphics environment. It includes functions for creating, destroying, and managing descriptor heaps, including CPU and GPU heaps. The component uses an arena-based memory allocator to efficiently allocate and deallocate descriptors, ensuring that the heap management is both efficient and easy to use. The component also provides functions for acquiring and releasing sampler heaps from a pool, which helps in optimizing resource usage by reusing descriptor heaps.
