# Bounds::GetVolume
|
|
|
|
```cpp
|
|
float GetVolume() const
|
|
```
|
|
|
|
计算包围盒的体积。返回 `extents.x * 2.0f * extents.y * 2.0f * extents.z * 2.0f`。
|
|
|
|
**返回：** `float` - 包围盒体积
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Math/Bounds.h>
|
|
#include <XCEngine/Math/Vector3.h>
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Bounds bounds(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 2.0f, 3.0f));
|
|
float vol = bounds.GetVolume();
|
|
// vol = 2 * 4 * 6 = 48
|
|
```
