# D3D12RootSignature::CreateStaticSampler

## 函数签名

```cpp
static D3D12_STATIC_SAMPLER_DESC CreateStaticSampler(uint32_t shaderRegister, const D3D12_SAMPLER_DESC& desc, ShaderVisibility visibility = ShaderVisibility::Pixel)
```

## 中文描述

创建静态采样器描述符，静态采样器绑定到根签名中无需描述符堆。

## 参数

| 参数 | 类型 | 描述 |
|------|------|------|
| `shaderRegister` | `uint32_t` | 着色器寄存器编号 |
| `desc` | `D3D12_SAMPLER_DESC` | 采样器描述符 |
| `visibility` | `ShaderVisibility` | 可见性（默认 Pixel） |

## 返回值

`D3D12_STATIC_SAMPLER_DESC` - 静态采样器描述符

## 复杂度

O(1)

## 示例

```cpp
D3D12_SAMPLER_DESC samplerDesc = D3D12RootSignature::CreateSamplerDesc(FilterMode::Anisotropic, TextureAddressMode::Wrap);
D3D12_STATIC_SAMPLER_DESC staticSampler = D3D12RootSignature::CreateStaticSampler(0, samplerDesc);
```
