+# Ray::Intersects (sphere)
+
+```cpp
+bool Intersects(const Sphere& sphere, float& t) const
+```
+
+检测射线是否与球体相交。
+
+**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
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Ray ray(cameraPosition, rayDirection);
+float t;
+if (ray.Intersects(sphere, t)) {
+    Vector3 hitPoint = ray.GetPoint(t);
+    // 处理命中
+}
+```
