# Bounds::Contains
```cpp
bool Contains(const Vector3& point) const
```
2026-03-20 02:35:15 +08:00
检测给定点是否在包围盒内部。边界上的点被视为在盒内。
**参数:**
- `point` - 要检测的点
2026-03-20 02:35:15 +08:00
**返回:** `bool` - true 表示点在盒内(包括边界)
**线程安全:** ✅
**复杂度:** O(1)
**示例:**
```cpp
2026-03-20 02:35:15 +08:00
#include <XCEngine/Math/Bounds.h>
#include <XCEngine/Math/Vector3.h>
using namespace XCEngine::Math;
Bounds bounds(Vector3(0.0f, 0.0f, 0.0f), Vector3(2.0f, 2.0f, 2.0f));
if (bounds.Contains(Vector3(0.0f, 0.0f, 0.0f))) {
// center is inside
}
if (!bounds.Contains(Vector3(10.0f, 0.0f, 0.0f))) {
// far away point is outside
}
```
