D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088 structure (d3d12umddi.h)
The D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088 structure specifies the range of subresources being transitioned.
Syntax
typedef struct D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088 {
UINT32 IndexOrFirstMipLevel;
UINT32 NumMipLevels;
UINT32 FirstArraySlice;
UINT32 NumArraySlices;
UINT32 FirstPlane;
UINT32 NumPlanes;
} D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088;
Members
IndexOrFirstMipLevel
If NumMipLevels is zero, IndexOrFirstMipLevel specifies a subresource index. A subresource index of 0xffffffff can be used to specify all subresources.
If NumMipLevels is not zero, IndexOrFirstMipLevel identifies the first mip level in the range.
NumMipLevels
The number of mip levels in the range, or zero to indicate IndexOrFirstMipLevel is a subresource index.
FirstArraySlice
Index of the first array slice in the range. FirstArraySlice is ignored if NumMipLevels is zero.
NumArraySlices
Number of array slices in the range. NumArraySlices is ignored if NumMipLevels is zero.
FirstPlane
The first plane slice in the range. FirstPlane is ignored if NumMipLevels is zero.
NumPlanes
The number of plane slices in the range. NumPlanes is ignored if NumMipLevels is zero.
Remarks
The D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088 structure allows developers to transition a range of subresources such as a full mip-chain for a given texture array or a single mip-level for all array slices. The Enhanced Barriers feature allows developers to transition logically-adjacent ranges of subresources using this structure.
See Enhanced Barriers for general information.
