# Vector3::Cross
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Vector3 Cross(const Vector3& a, const Vector3& b)
|
||
|
|
```
|
||
|
|
|
||
|
|
计算两个 3D 向量的叉积。结果向量同时垂直于 a 和 b。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `a` - 第一个向量
|
||
|
|
- `b` - 第二个向量
|
||
|
|
|
||
|
|
**返回：** `Vector3` - 叉积结果，垂直于 a 和 b 的向量
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 right(1.0f, 0.0f, 0.0f);
|
||
|
|
Vector3 up(0.0f, 1.0f, 0.0f);
|
||
|
|
Vector3 forward = Vector3::Cross(right, up); // (0, 0, 1)
|
||
|
|
```
