Members

pMipInfoList

[in] An array of D3D10DDI_MIPINFO structures that contains dimensions for MIP levels. For resource formats where a single pixel or texel cannot be referenced directly with a byte address, the dimensions of the physical resource are typically larger or equal to the texel dimensions, in order to satisfy the necessary space requirements. For example, to create a fully mipped BC1 Texture2D, where the most detailed level is 8x8, the pMipInfoList array is: { { 8, 8, 1, 8, 8, 1 }, { 4, 4, 1, 4, 4, 1 }, { 2, 2, 1, 4, 4, 1 }, { 1, 1, 1, 4, 4, 1 } }.

pInitialDataUP

[in] An array of D3D10_DDIARG_SUBRESOURCE_UP structures that provides initialization information for the resource's list of subresources.

ResourceDimension

[in] A value of type D3D10DDIRESOURCE_TYPE that indicates the resource type and dimensionality.

Usage

[in] A value of type D3D10_DDI_RESOURCE_USAGE that indicates how the resource is used.

BindFlags

[in] A valid bitwise OR of D3D10_DDI_RESOURCE_BIND_FLAG values that indicates how the resource is bound.

MapFlags

[in] A value of type D3D10_DDI_MAP that indicates the access level to map to the resource.

MiscFlags

[in] A valid bitwise OR of D3D10_DDI_RESOURCE_MISC_FLAG values that indicates miscellaneous information about the resource.

Format

[in] A value of type DXGI_FORMAT that indicates the pixel format of the resource.

SampleDesc

[in] A value of type DXGI_SAMPLE_DESC that describes the sample count and quality of the resource.

MipLevels

[in] The number of MIP-map levels for the resource.

ArraySize

[in] The number of array elements for a 2-D texture or 1-D texture. ArraySize must be set to 6 for a cube texture.

Beginning in Windows 8, if the driver must create a stereo back buffer, it should set this member to a value of 2.

pPrimaryDesc

[in, out] A pointer to a DXGI_DDI_PRIMARY_DESC structure that describes a resource that is used as a primary.

The Microsoft Direct3D runtime sets pPrimaryDesc to a non-NULL value only if the D3D10_DDI_BIND_PRESENT bit is set in the BindFlags member; however, even if D3D10_DDI_BIND_PRESENT is set, the runtime does not always set pPrimaryDesc to non-NULL. Setting pPrimaryDesc to non-NULL indicates that the runtime will use the created resource as a primary (that is, the resource is scanned out to the display) and in flip-style present operations.

The user-mode display driver can return the DXGI_DDI_PRIMARY_DRIVER_FLAG_NO_SCANOUT flag in the DriverFlags member of DXGI_DDI_PRIMARY_DESC to prevent the runtime from performing flip-style present operations.

If pPrimaryDesc is set to NULL, the runtime will use the created resource in copy-style (bit-block transfer) present operations.
