# Frustum::Contains
|
|
|
|
```cpp
|
|
bool Contains(const Sphere& sphere) const
|
|
```
|
|
|
|
检测球体是否完全位于视锥体内。判断方式为：依次计算球心到 6 个裁剪平面的有符号距离，若任意一个距离小于 `-radius`（即球心到平面的距离小于球半径的负数，说明球体完全在平面外侧），则视锥体不包含该球体。
|
|
|
|
**参数：**
|
|
- `sphere` - 要检测的球体，包含圆心 `center` 和半径 `radius`
|
|
|
|
**返回：** `bool` - 球体完全在视锥内返回 `true`，否则返回 `false`
|
|
|
|
**线程安全：** ✅（只读操作，不修改状态）
|
|
|
|
**复杂度：** O(6)，即遍历 6 个裁剪平面
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Core/Math/Frustum.h>
|
|
#include <XCEngine/Core/Math/Sphere.h>
|
|
|
|
void CheckSphereInFrustum(const Frustum& frustum, const Sphere& sphere) {
|
|
if (frustum.Contains(sphere)) {
|
|
// 球体完全在视锥内
|
|
}
|
|
}
|
|
```
