# D3D12XBOX_DISPATCH_RAYS_DESC (consoles XBOX Series)

> Extension XBOX de D3D12_DISPATCH_RAYS_DESC

Extension XBOX de [D3D12\_DISPATCH\_RAYS\_DESC](https://learn.microsoft.com/en-us/windows/win32/api/d3d12/ns-d3d12-d3d12_dispatch_rays_desc)

## Syntaxe

```cpp theme={null}
typedef struct D3D12XBOX_DISPATCH_RAYS_DESC {  
    D3D12_DISPATCH_RAYS_DESC DispatchArgs;  
    D3D12_GPU_VIRTUAL_ADDRESS_RANGE Scratch;  
    D3D12XBOX_XDXR_STREAM_DESC ExtraOptions;  
} D3D12XBOX_DISPATCH_RAYS_DESC  
```

### Membres

*DispatchArgs*\
Type : D3D12\_DISPATCH\_RAYS\_DESC

Arguments DispatchRays D3D standard.

*Scratch*\
Type : D3D12\_GPU\_VIRTUAL\_ADDRESS\_RANGE

Remplacement facultatif de la mémoire de travail.

*ExtraOptions*\
Type : [D3D12XBOX\_XDXR\_STREAM\_DESC](/fr-CA/reference/graphics/d3d12_xs/structs/d3d12xbox_xdxr_stream_desc)

Options supplémentaires, inutilisées dans les GDK d'août.

## Remarques

Exemple 1 -- une application utilise sa propre allocation de mémoire et doit assurer une synchronisation appropriée

```CPP theme={null}
D3D12XBOX_DISPATCH_RAYS_DESC dispatchDescX {};
dispatchDescX.DispatchArgs = dispatchDesc;
dispatchDescX.Scratch.StartAddress = m_customStackScratch->GetGPUVirtualAddress();
dispatchDescX.Scratch.SizeInBytes = CUSTOM_SCRATCH_SIZE;
m_commandList->DispatchRaysX(&dispatchDescX);  
```

## Configuration requise
