# D3D12_SERIALIZED_RAYTRACING_ACCELERATION_STRUCTURE_HEADER

> Define o cabeçalho de uma estrutura de aceleração de traçado de raios serializada.

Define o cabeçalho de uma estrutura de aceleração de traçado de raios serializada.

## Sintaxe

```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
```

### Membros

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

O identificador de correspondência do driver.

*SerializedSizeInBytesIncludingHeader*\
Tipo: UINT64

O tamanho dos dados serializados.

*DeserializedSizeInBytes*\
Tipo: UINT64

Tamanho da memória que será consumida quando a estrutura de aceleração for desserializada.  Esse valor é menor ou igual ao tamanho da estrutura de aceleração original antes de ela ser serializada.

*NumBottomLevelAccelerationStructurePointersAfterHeader*\
Tipo: UINT64

Tamanho da matriz de valores [D3D12\_GPU\_VIRTUAL\_ADDRESS](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/d3d12_gpu_virtual_address) que seguem o cabeçalho.
