ID3D10Device::ResolveSubresource method
Copy a multisampled resource into a non-multisampled resource. This API is most useful when re-using the resulting rendertarget of one render pass as an input to a second render pass.
Syntax
void ResolveSubresource( [in] ID3D10Resource *pDstResource, [in] UINT DstSubresource, [in] ID3D10Resource *pSrcResource, [in] UINT SrcSubresource, [in] DXGI_FORMAT Format );
Parameters
- pDstResource [in]
-
Type: ID3D10Resource*
Destination resource. Must be a created with the D3D10_USAGE_DEFAULT flag and be single-sampled. See ID3D10Resource.
- DstSubresource [in]
-
Type: UINT
A zero-based index, that identifies the destination subresource. See D3D10CalcSubresource for more details.
- pSrcResource [in]
-
Type: ID3D10Resource*
Source resource. Must be multisampled.
- SrcSubresource [in]
-
Type: UINT
The source subresource of the source resource.
- Format [in]
-
Type: DXGI_FORMAT
DXGI_FORMAT that indicates how the multisampled resource will be resolved to a single-sampled resource. See remarks.
Return value
Returns nothing.
Remarks
Both the source and destination resources must be the same resource type and have the same dimensions.
The source and destination must have compatible formats. There are three scenarios for this:
| Scenario | Requirements |
|---|---|
| Source and destination are prestructured and typed | Both the source and destination must have identical formats and that format must be specified in the Format parameter. |
| One resource is prestructured and typed and the other is prestructured and typeless | The typed resource must have a format that is compatible with the typeless resource (i.e. the typed resource is DXGI_FORMAT_R32_FLOAT and the typeless resource is DXGI_FORMAT_R32_TYPELESS). The format of the typed resource must be specified in the Format parameter. |
| Source and destination are prestructured and typeless | Both the source and desintation must have the same typeless format (i.e. both must have DXGI_FORMAT_R32_TYPELESS), and the Format parameter must specify a format that is compatible with the source and destination (i.e. if both are DXGI_FORMAT_R32_TYPELESS then DXGI_FORMAT_R32_FLOAT or DXGI_FORMAT_R32_UINT could be specified in the Format parameter). |
