# RHICommandList::SetIndexBuffer
|
||
|
||
```cpp
|
||
virtual void SetIndexBuffer(void* buffer, uint64_t offset, Format format) = 0;
|
||
```
|
||
|
||
绑定索引缓冲区。索引缓冲区存储顶点索引，用于 `DrawIndexed` 调用，从顶点缓冲区中选择顶点组成图元。
|
||
|
||
**参数：**
|
||
- `buffer` - 索引缓冲区指针
|
||
- `offset` - 缓冲区内的起始偏移量（字节）
|
||
- `format` - 索引格式（Format::R16_UINT 或 Format::R32_UINT）
|
||
|
||
**返回：** `void`
|
||
|
||
**异常：** 无
|
||
|
||
**线程安全：** ❌
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
cmdList->SetIndexBuffer(indexBuffer, 0, Format::R16_UINT);
|
||
```
