# Ray::Intersects (sphere)
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
bool Intersects(const Sphere& sphere, float& t) const
|
|||
|
|
```
|
|||
|
|
|
|||
|
|

|
|
|||
|
|
**参数：**
|
|||
|
|
- `sphere` - 要检测的球体
|
|||
|
|
- `t` - 输出最近交点的参数距离
|
|||
|
|
|
|||
|
|
**返回：** `bool` - 相交返回 true，否则返回 false
|

Ray ray(cameraPosition, rayDirection);
|
|||
|
|
float t;
|
|||
|
|
if (ray.Intersects(sphere, t)) {
|
|||
|
|
Vector3 hitPoint = ray.GetPoint(t);
