Members
Filter
Type: D3D11_FILTER
Filtering method to use when sampling a texture (see D3D11_FILTER).
AddressU
Type: D3D11_TEXTURE_ADDRESS_MODE
Method to use for resolving a u texture coordinate that is outside the 0 to 1 range (see D3D11_TEXTURE_ADDRESS_MODE).
AddressV
Type: D3D11_TEXTURE_ADDRESS_MODE
Method to use for resolving a v texture coordinate that is outside the 0 to 1 range.
AddressW
Type: D3D11_TEXTURE_ADDRESS_MODE
Method to use for resolving a w texture coordinate that is outside the 0 to 1 range.
MipLODBias
Type: FLOAT
Offset from the calculated mipmap level. For example, if Direct3D calculates that a texture should be sampled at mipmap level 3 and MipLODBias is 2, then the texture will be sampled at mipmap level 5.
MaxAnisotropy
Type: UINT
Clamping value used if D3D11_FILTER_ANISOTROPIC or D3D11_FILTER_COMPARISON_ANISOTROPIC is specified in Filter. Valid values are between 1 and 16.
ComparisonFunc
Type: D3D11_COMPARISON_FUNC
A function that compares sampled data against existing sampled data. The function options are listed in D3D11_COMPARISON_FUNC.
BorderColor[4]
Type: FLOAT[4]
Border color to use if D3D11_TEXTURE_ADDRESS_BORDER is specified for AddressU, AddressV, or AddressW. Range must be between 0.0 and 1.0 inclusive.
MinLOD
Type: FLOAT
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
Type: FLOAT
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 to a large value such as D3D11_FLOAT32_MAX.
Remarks
These are the default values for sampler state.
