D3D12_TEXCUBE_ARRAY_SRV structure (d3d12.h)
Describes the subresources from an array of cube textures to use in a shader-resource view.
Syntax
typedef struct D3D12_TEXCUBE_ARRAY_SRV {
UINT MostDetailedMip;
UINT MipLevels;
UINT First2DArrayFace;
UINT NumCubes;
FLOAT ResourceMinLODClamp;
} D3D12_TEXCUBE_ARRAY_SRV;
Members
MostDetailedMip
Index of the most detailed mipmap level to use; this number is between 0 and MipLevels (from the original TextureCube for which ID3D12Device::CreateShaderResourceView creates a view) -1.
MipLevels
The maximum number of mipmap levels for the view of the texture. See the remarks in D3D12_TEX1D_SRV.
Set to -1 to indicate all the mipmap levels from MostDetailedMip on down to least detailed.
First2DArrayFace
Index of the first 2D texture to use.
NumCubes
Number of cube textures in the array.
ResourceMinLODClamp
Specifies the minimum mipmap level that you can access. Specifying 0.0f means that you can access all of the mipmap levels. Specifying 3.0f means that you can access mipmap levels from 3.0f to MipCount - 1.
We recommend that you don't set MostDetailedMip and ResourceMinLODClamp at the same time. Instead, set one of those two members to 0 (to get default behavior). That's because MipLevels is interpreted differently in conjunction with different fields:
- For MostDetailedMip, mips are in the range [MostDetailedMip, MostDetailedMip + MipLevels - 1].
- For ResourceMinLODClamp, mips are in the range [ResourceMinLODClamp, MipLevels - 1].
Remarks
This structure is one member of a shader-resource-view description, D3D12_SHADER_RESOURCE_VIEW_DESC.
