內嵌深度() const
-
如果 Dimension == D3D12_RESOURCE_DIMENSION_TEXTURE3D,則會傳回 DepthOrArraySize。 如果 Dimension != D3D12_RESOURCE_DIMENSION_TEXTURE3D,則傳回 1。
-
inline ArraySize() const
-
如果 Dimension != D3D12_RESOURCE_DIMENSION_TEXTURE3D,則會傳回 DepthOrArraySize。 如果 Dimension == D3D12_RESOURCE_DIMENSION_TEXTURE3D,則傳回 1。 請參閱 D3D12_RESOURCE_DIMENSION_TEXTURE3D。
-
inline PlaneCount(ID3D12Device* pDevice) const
-
會傳回 D3D12GetFormatPlaneCount(pDevice,Format)。 請參閱 D3D12GetFormatPlaneCount 和 ID3D12Device。
-
inline Subresources(ID3D12Device* pDevice) const
-
傳回子資源的數目,計算為 MipLevels * ArraySize() * PlaneCount(pDevice)。
-
inline CalcSubresource(UINT MipSlice, UINT ArraySlice, UINT PlaneSlice)
-
使用 D3D12CalcSubresource 計算子資源索引。
-
operator const D3D12_RESOURCE_DESC&() const
-
定義父結構類型的 和 傳遞參考運算元。
-
operator == (const D3D12_RESOURCE_DESC& l, const D3D12_RESOURCE_DESC& r)
-
如果每個結構的所有成員都相同,則傳回 true。
-
operator != (const D3D12_RESOURCE_DESC& l, const D3D12_RESOURCE_DESC& r)
-
如果每個結構的所有成員都相同,則傳回 false。
