# Vector4::ToVector3
|
||
|
||
将 Vector4 转换为 Vector3，丢弃 w 分量。
|
||
|
||
```cpp
|
||
Vector3 ToVector3() const
|
||
```
|
||
|
||
**返回：** `Vector3` - 转换后的 Vector3 (x, y, z)
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
Vector4 pos4(1.0f, 2.0f, 3.0f, 1.0f);
|
||
Vector3 pos3 = pos4.ToVector3(); // (1, 2, 3)
|
||
```
