# Ray::Intersects (sphere)
|
||
|
||
```cpp
|
||
bool Intersects(const Sphere& sphere, float& t) const
|
||
```
|
||
|
||
检测射线是否与球体相交。使用二次方程求根法计算交点。
|
||
|
||
**参数：**
|
||
- `sphere` - 要检测的球体
|
||
- `t` - 输出最近交点的参数距离（仅在返回 true 时有效，若射线在球体内部则输出最近的出口点）
|
||
|
||
**返回：** `bool` - 相交返回 true，否则返回 false
|
||
|
||
**线程安全：** ✅
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**异常：** 无
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include <XCEngine/Core/Math/Ray.h>
|
||
#include <XCEngine/Core/Math/Sphere.h>
|
||
#include <XCEngine/Core/Math/Vector3.h>
|
||
|
||
using namespace XCEngine::Math;
|
||
|
||
Ray ray(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 0.0f, 0.0f));
|
||
Sphere sphere(Vector3(10.0f, 0.0f, 0.0f), 1.0f);
|
||
float t;
|
||
if (ray.Intersects(sphere, t)) {
|
||
Vector3 hitPoint = ray.GetPoint(t);
|
||
}
|
||
```
