# ID3D12DescriptorHeap

> A descriptor heap is a collection of contiguous allocations of descriptors, one allocation for every descriptor.

A descriptor heap is a collection of contiguous allocations of descriptors, one allocation for every descriptor. Descriptor heaps contain many object types that are not part of a Pipeline State Object (PSO), such as Shader Resource Views (SRVs), Unordered Access Views (UAVs), Constant Buffer Views (CBVs), and Samplers.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
**Supported Platforms**: XBOX Series consoles and XBOX One family
