# OBB::Intersects (Sphere)
```cpp
bool Intersects(const Sphere& sphere) const;
```
检测该 OBB 与球体是否相交。将球心变换到 OBB 的局部坐标系,然后在局部空间中计算球心到盒子的最近点,最后判断距离是否小于球体半径。
**参数:**
- `sphere` - 待检测的球体
**返回:** OBB 与球体相交返回 `true`,否则返回 `false`
**异常:**
**线程安全:**
**复杂度:** O(1)
**示例:**
```cpp
#include "AABB.h"
#include "Vector3.h"
#include "Sphere.h"
using namespace XCEngine::Math;
OBB obb(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 0.5f, 1.0f));
Sphere sphere(Vector3(0.5f, 0.0f, 0.0f), 0.5f);
if (obb.Intersects(sphere)) {
}
```
