+# OBB::Intersects (OBB)
+
+```cpp
+bool Intersects(const OBB& other) const
+```
+
+检测两个 OBB 是否相交（使用 SAT 分离轴定理）。
+
+**参数：**
+- `other` - 另一个 OBB
+
+**返回：** `bool` - true 表示相交
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+OBB obbA = ...;
+OBB obbB = ...;
+if (obbA.Intersects(obbB)) {
+    // 两个有向包围盒相交
+}
+```
