# 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);
|
|
```
