Binding Model

Writable storage bindings:

1. Binding: 0 .. D3D11_PS_CS_UAV_REGISTER_COUNT

Other bindings:

1. Shader stage: vs, fs, cs
2. Register: constant buffers (CBV), shader resources (SRV), samplers
3. Binding (tight)

Pipeline Layout

In D3D11 there are tables of CBVs, SRVs, UAVs, and samplers.

Each descriptor type can take 1 or two of those entry points.

The descriptor pool is just and array of handles, belonging to descriptor set 1, descriptor set 2, etc. Each range of descriptors in a descriptor set area of the pool is split into shader stages, which in turn is split into CBS/SRV/UAV/Sampler parts. That allows binding a descriptor set as a list of continuous descriptor ranges (per type, per shader stage).
