# 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 a，1 返回 b
|
|||
|
|
|
|||
|
|
**返回：** `Vector3` - 插值结果
|
|||
|
|
|
|||
|
|
**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)
|
|||
|
|
```
