# Vector3::Lerp
```cpp
static Vector3 Lerp(const Vector3& a, const Vector3& b, float t)
```
在线性插值两个向量之间。参数 t 会在 [0, 1] 范围内被限制。
**参数:**
- `a` - 起始向量
- `b` - 结束向量
- `t` - 插值因子0 返回 a1 返回 b
**返回:** `Vector3` - 插值结果
**线程安全:**
**复杂度:** O(1)
**示例:**
```cpp
Vector3 start(0.0f, 0.0f, 0.0f);
Vector3 end(10.0f, 10.0f, 10.0f);
Vector3 mid = Vector3::Lerp(start, end, 0.5f); // (5.0f, 5.0f, 5.0f)
```
