Mitglieder
Filter
Typ: D3D11_FILTERFiltering method to use when sampling a texture (see D3D11_FILTER).
AddressU
Typ: D3D11_TEXTURE_ADDRESS_MODEMethod to use for resolving a u texture coordinate that is outside the 0 to 1 range (see D3D11_TEXTURE_ADDRESS_MODE).
AddressV
Typ: D3D11_TEXTURE_ADDRESS_MODEMethod to use for resolving a v texture coordinate that is outside the 0 to 1 range.
AddressW
Typ: D3D11_TEXTURE_ADDRESS_MODEMethod to use for resolving a w texture coordinate that is outside the 0 to 1 range.
MipLODBias
Typ: FLOATOffset 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
Typ: UINTClamping value used if D3D11_FILTER_ANISOTROPIC or D3D11_FILTER_COMPARISON_ANISOTROPIC is specified in Filter. Valid values are between 1 and 16.
ComparisonFunc
Typ: D3D11_COMPARISON_FUNCA function that compares sampled data against existing sampled data. The function options are listed in D3D11_COMPARISON_FUNC.
BorderColor
Typ: FLOATBorder 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
Typ: FLOATLower 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
Typ: FLOATUpper 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.
