D3D12_SAMPLER_DESC structure (d3d12.h)

Describes a sampler state.

Syntax

Members

Filter

A D3D12_FILTER-typed value that specifies the filtering method to use when sampling a texture.

AddressU

A D3D12_TEXTURE_ADDRESS_MODE-typed value that specifies the method to use for resolving a u texture coordinate that is outside the 0 to 1 range.

AddressV

A D3D12_TEXTURE_ADDRESS_MODE-typed value that specifies the method to use for resolving a v texture coordinate that is outside the 0 to 1 range.

AddressW

A D3D12_TEXTURE_ADDRESS_MODE-typed value that specifies the method to use for resolving a w texture coordinate that is outside the 0 to 1 range.

MipLODBias

Offset from the calculated mipmap level. For example, if the runtime calculates that a texture should be sampled at mipmap level 3 and MipLODBias is 2, the texture will be sampled at mipmap level 5.

MaxAnisotropy

Clamping value used if D3D12_FILTER_ANISOTROPIC or D3D12_FILTER_COMPARISON_ANISOTROPIC is specified in Filter. Valid values are between 1 and 16.

ComparisonFunc

A D3D12_COMPARISON_FUNC-typed value that specifies a function that compares sampled data against existing sampled data.

BorderColor[4]

RGBA border color to use if D3D12_TEXTURE_ADDRESS_MODE_BORDER is specified for AddressU, AddressV, or AddressW. Range must be between 0.0 and 1.0 inclusive.

MinLOD

Lower end of the mipmap range to clamp access to, where 0 is the largest and most detailed mipmap level and any level higher than that is less detailed.

MaxLOD

Upper end of the mipmap range to clamp access to, where 0 is the largest and most detailed mipmap level and any level higher than that is less detailed. This value must be greater than or equal to MinLOD. To have no upper limit on LOD, set this member to a large value.

Remarks

This structure is used by CreateSampler.
