# OBB::Contains

```cpp
bool Contains(const Vector3& point) const;
```

检测给定点是否位于 OBB 包围盒内部。通过将点变换到局部坐标系，然后检查其坐标分量是否在半长向量范围内。

**参数：**
- `point` - 待检测的三维点

**返回：** 点在包围盒内返回 `true`，否则返回 `false`

**异常：** 无

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
#include "AABB.h"
#include "Vector3.h"

using namespace XCEngine::Math;

OBB obb(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 0.5f, 1.0f));

Vector3 insidePoint(0.0f, 0.0f, 0.0f);
Vector3 outsidePoint(2.0f, 0.0f, 0.0f);

bool isInside = obb.Contains(insidePoint);
bool isOutside = obb.Contains(outsidePoint);
```
