# Frustum::Contains (bounds)

```cpp
bool Contains(const Bounds& bounds) const
```

检测轴对齐包围盒是否完全在视锥体内。

**参数：**
- `bounds` - 要检测的轴对齐包围盒

**返回：** `bool` - Bounds 完全在视锥内返回 true

**复杂度：** O(1)

**示例：**

```cpp
Frustum frustum = camera.CalculateFrustum();
Bounds objectBounds = object.GetWorldBounds();
if (frustum.Contains(objectBounds)) {
    // 包围盒完全在视锥内，需要渲染
    Render(object);
}
```
