# Vector3::Project
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
static Vector3 Project(const Vector3& vector, const Vector3& onNormal)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
将向量投影到法线向量上。
|
|||
|
|
|
|||
|
|
**参数：**
|
|||
|
|
- `vector` - 要投影的向量
|
|||
|
|
- `onNormal` - 投影到的法线向量
|
|||
|
|
|
|||
|
|
**返回：** `Vector3` - 投影结果。如果法线长度为 0，返回零向量。
|
|||
|
|
|
|||
|
|
**复杂度：** O(1)
|
|||
|
|
|
|||
|
|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
Vector3 v(1.0f, 1.0f, 0.0f);
|
|||
|
|
Vector3 normal(1.0f, 0.0f, 0.0f);
|
|||
|
|
Vector3 projected = Vector3::Project(v, normal); // (1, 0, 0)
|
|||
|
|
```
