# D3D12_INDEX_BUFFER_VIEW

> 描述要查看的索引缓冲区。

描述要查看的索引缓冲区。

## 语法

```cpp theme={null}
typedef struct D3D12_INDEX_BUFFER_VIEW
{
    D3D12_GPU_VIRTUAL_ADDRESS BufferLocation;
    UINT SizeInBytes;
    DXGI_FORMAT Format;
} D3D12_INDEX_BUFFER_VIEW
```

### 成员

*BufferLocation*\
类型：D3D12\_GPU\_VIRTUAL\_ADDRESS

索引缓冲区的 GPU 虚拟地址。
D3D12\_GPU\_VIRTUAL\_ADDRESS 是 UINT64 的 typedef 同义词。

*SizeInBytes*\
类型：UINT

索引缓冲区的大小（以字节为单位）。

*Format*\
类型：DXGI\_FORMAT

一个 [DXGI\_FORMAT](https://learn.microsoft.com/en-us/windows/desktop/api/dxgiformat/ne-dxgiformat-dxgi_format) 类型的值，用于索引缓冲区格式。
