# Vector3::operator*
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 operator*(float scalar) const
|
||
|
|
Vector3 operator*(const Vector3& other) const
|
||
|
|
```
|
||
|
|
|
||
|
|
向量乘法。支持向量与标量相乘，以及向量分量对应相乘。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `scalar` - 标量值（用于第一个重载）
|
||
|
|
- `other` - 向量（用于第二个重载，分量相乘）
|
||
|
|
|
||
|
|
**返回：** `Vector3` - 乘法结果
|
||
|
|
|
||
|
|
**线程安全：** ✅
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 v(1.0f, 2.0f, 3.0f);
|
||
|
|
|
||
|
|
// 标量乘法
|
||
|
|
Vector3 scaled = v * 2.0f; // (2.0f, 4.0f, 6.0f)
|
||
|
|
|
||
|
|
// 分量相乘
|
||
|
|
Vector3 a(1.0f, 2.0f, 3.0f);
|
||
|
|
Vector3 b(2.0f, 3.0f, 4.0f);
|
||
|
|
Vector3 componentwise = a * b; // (2.0f, 6.0f, 12.0f)
|
||
|
|
```
