access view (UAV) means that the shader writes to the resource. In some cases

you can read and write the resource, but this is limited to resources with a na-

tive 32-bit template type; for example,

RWTexture2D<float>. The bind point is

zero, which is needed by the application for attaching the resource for shader

execution. The return type is also

D3D RETURN TYPE FLOAT, but the flag’s

value is f = 0 which implies there is 1 = 1 + (f>>2) component. Thus,

the reflection indicates that

output was declared as RWTexture1D<float>.The

dimension is reported as

D3D SRV DIMENSION TEXTURE1D.
