## 概述
|
|||
|
|
|
|||
|
|
`RHIFactory` 是静态工厂类，提供统一的接口来创建不同后端的 `RHIDevice` 实例。通过 `RHIType` 枚举指定要创建的后端类型。

|
|
| [`CreateRHIDevice(RHIType)`](create-rhi-device-type.md) | 使用枚举类型创建 RHI 设备 |
|
|||
|
|
| [`CreateRHIDevice(std::string)`](create-rhi-device-string.md) | 使用字符串创建 RHI 设备 |

|----------|-----------------|
|
|||
|
|
| `RHIType::D3D12` | `"D3D12"` |
|
|||

## 使用示例
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
// 方法1：使用枚举创建
|
|||
|
|
RHIDevice* d3d12Device = RHIFactory::CreateRHIDevice(RHIType::D3D12);
|
|||
|
|
|
|||
|
|
// 方法2：使用字符串创建
|
|||
|
|
RHIDevice* glDevice = RHIFactory::CreateRHIDevice("OpenGL");
|
|||
|
|
|
|||
|
|
// 方法3：根据配置选择
|
|||
|
|
std::string backend = "D3D12";
|
|||
|
|
RHIDevice* device = RHIFactory::CreateRHIDevice(backend);
|
|||
|
|
```
