# 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:** 无
|
|
|
|
**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)) {
|
|
}
|
|
```
