### Members

*Dimension*\
Type: D3D12\_RESOURCE\_DIMENSION

One member of [D3D12\_RESOURCE\_DIMENSION](/reference/graphics/d3d12_x/enums/d3d12_resource_dimension), specifying the dimensions of the resource (for example, D3D12\_RESOURCE\_DIMENSION\_TEXTURE1D), or whether it is a buffer ((D3D12\_RESOURCE\_DIMENSION\_BUFFER).

*Alignment*\
Type: UINT64

Specifies the alignment.

*Width*\
Type: UINT64

Specifies the width of the resource.

*Height*\
Type: UINT

Specifies the height of the resource.

*DepthOrArraySize*\
Type: UINT16

Specifies the depth of the resource, if it is 3D, or the array size if it is an array of 1D or 2D resources.

*MipLevels*\
Type: UINT16

Specifies the number of MIP levels.

*Format*\
Type: DXGI\_FORMAT

Specifies one member of [DXGI\_FORMAT](https://learn.microsoft.com/en-us/windows/win32/api/dxgiformat/ne-dxgiformat-dxgi_format).

*SampleDesc*\
Type: DXGI\_SAMPLE\_DESC

Specifies a [DXGI\_SAMPLE\_DESC](https://learn.microsoft.com/en-us/windows/win32/api/dxgicommon/ns-dxgicommon-dxgi_sample_desc) structure.

*Layout*\
Type: D3D12\_TEXTURE\_LAYOUT

Specifies one member of [D3D12\_TEXTURE\_LAYOUT](/reference/graphics/d3d12_x/enums/d3d12_texture_layout).

*Flags*\
Type: D3D12\_RESOURCE\_FLAGS

Bitwise-OR'd flags, as [D3D12\_RESOURCE\_FLAGS](/reference/graphics/d3d12_x/enums/d3d12_resource_flags) enumeration constants.

*SamplerFeedbackMipRegion*\
Type: D3D12\_MIP\_REGION

A [D3D12\_MIP\_REGION](/reference/graphics/d3d12_xs/structs/d3d12_mip_region) struct.
