计算包围盒的体积。返回 `extents.x * 2.0f * extents.y * 2.0f * extents.z * 2.0f`
2026-03-20 02:35:15 +08:00
**返回:** `float` - 包围盒体积
**线程安全:** ✅
**复杂度:** O(1)
**示例:**
```cpp
2026-03-20 02:35:15 +08:00
#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();
2026-03-20 02:35:15 +08:00
// vol = 2 * 4 * 6 = 48
```
