# D3D12_SERIALIZED_RAYTRACING_ACCELERATION_STRUCTURE_HEADER

> Define el encabezado de una estructura de aceleración de trazado de rayos serializada.

Define el encabezado de una estructura de aceleración de trazado de rayos serializada.

## Sintaxis

```cpp theme={null}
typedef struct D3D12_SERIALIZED_RAYTRACING_ACCELERATION_STRUCTURE_HEADER
{
    D3D12_SERIALIZED_DATA_DRIVER_MATCHING_IDENTIFIER DriverMatchingIdentifier;
    UINT64 SerializedSizeInBytesIncludingHeader;
    UINT64 DeserializedSizeInBytes;
    UINT64 NumBottomLevelAccelerationStructurePointersAfterHeader;
} D3D12_SERIALIZED_RAYTRACING_ACCELERATION_STRUCTURE_HEADER
```

### Miembros

*DriverMatchingIdentifier*\
Tipo: D3D12\_SERIALIZED\_DATA\_DRIVER\_MATCHING\_IDENTIFIER

El identificador de coincidencia de controladores.

*SerializedSizeInBytesIncludingHeader*\
Tipo: UINT64

El tamaño de los datos serializados.

*DeserializedSizeInBytes*\
Tipo: UINT64

Tamaño de la memoria que se consumirá cuando se deserialice la estructura de aceleración.  Este valor es menor o igual que el tamaño de la estructura de aceleración original antes de serializarse.

*NumBottomLevelAccelerationStructurePointersAfterHeader*\
Tipo: UINT64

Tamaño de la matriz de valores [D3D12\_GPU\_VIRTUAL\_ADDRESS](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/d3d12_gpu_virtual_address) que siguen al encabezado.
