# 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);
}
```
