+# Ray::Intersects (plane)
+
+```cpp
+bool Intersects(const Plane& plane, float& t) const
+```
+
+检测射线是否与平面相交。
+
+**参数：**
+- `plane` - 要检测的平面
+- `t` - 输出交点的参数距离
+
+**返回：** `bool` - 相交返回 true（射线朝向平面），否则返回 false
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Ray ray(cameraPosition, rayDirection);
+Plane groundPlane = Plane::FromNormalAndPoint(Vector3::Up(), Vector3::Zero());
+float t;
+if (ray.Intersects(groundPlane, t)) {
+    Vector3 hitPoint = ray.GetPoint(t);
+    // 射线命中地面
+}
+```
