# D3D12Device::CreateBuffer

```cpp
RHIBuffer* CreateBuffer(const BufferDesc& desc) override;
```

创建 D3D12 缓冲区资源。

**参数：**
- `desc` - 缓冲区描述符，包含大小、类型、标志等

**返回：** 新创建的缓冲区指针，失败返回 `nullptr`

**复杂度：** O(1)

**示例：**

```cpp
BufferDesc bufferDesc;
bufferDesc.size = sizeof(Vertex) * vertexCount;
bufferDesc.stride = sizeof(Vertex);
bufferDesc.bufferType = (uint32_t)BufferType::Vertex;
bufferDesc.flags = 0;

RHIBuffer* vertexBuffer = device->CreateBuffer(bufferDesc);
```
