D3D12_SAMPLER_FEEDBACK_TIER enumeration (d3d12.h)
Defines constants that specify sampler feedback support.
Syntax
typedef enum D3D12_SAMPLER_FEEDBACK_TIER {
D3D12_SAMPLER_FEEDBACK_TIER_NOT_SUPPORTED = 0,
D3D12_SAMPLER_FEEDBACK_TIER_0_9 = 90,
D3D12_SAMPLER_FEEDBACK_TIER_1_0 = 100
} ;
Constants
D3D12_SAMPLER_FEEDBACK_TIER_NOT_SUPPORTED Value: 0 Specifies that sampler feedback is not supported. Attempts at calling sampler feedback APIs represent an error. |
D3D12_SAMPLER_FEEDBACK_TIER_0_9 Value: 90 Specifies that sampler feedback is supported to tier 0.9. This indicates the following: Sampler feedback is supported for samplers with these texture addressing modes: * D3D12_TEXTURE_ADDRESS_MODE_WRAP * D3D12_TEXTURE_ADDRESS_MODE_CLAMP The Texture2D shader resource view passed in to feedback-writing HLSL methods has these restrictions: * The MostDetailedMip field must be 0. * The MipLevels count must span the full mip count of the resource. * The PlaneSlice field must be 0. * The ResourceMinLODClamp field must be 0. The Texture2DArray shader resource view passed in to feedback-writing HLSL methods has these restrictions: * All the limitations as in Texture2D above, and * The FirstArraySlice field must be 0. * The ArraySize field must span the full array element count of the resource. |
D3D12_SAMPLER_FEEDBACK_TIER_1_0 Value: 100 Specifies sample feedback is supported to tier 1.0. This indicates that sampler feedback is supported for all texture addressing modes, and feedback-writing methods are supported irrespective of the passed-in shader resource view. |
