|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
inline D3D12_INDEX_BUFFER_VIEW CreateIndexBufferView(
|
|||
|
|
D3D12_GPU_VIRTUAL_ADDRESS bufferLocation,
|
|||
|
|
UINT sizeInBytes,
|
|||
|
|
DXGI_FORMAT format
|
|||
|
|

|
|
- `bufferLocation` - 索引缓冲区 GPU 虚拟地址
|
|||
|
|
- `sizeInBytes` - 缓冲区大小（字节）
|
|||
|
|
- `format` - 索引格式（DXGI_FORMAT_R16_UINT 或 DXGI_FORMAT_R32_UINT）

**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|

|
|||
|
|
D3D12_INDEX_BUFFER_VIEW ibView = CreateIndexBufferView(
|
|||
|
|
indexBuffer->GetGPUVirtualAddress(),
|
|||
|
|
indexBufferSize,
|
|||
|
|
DXGI_FORMAT_R16_UINT
|
|||
|
|
);
|
