# Sphere::Sphere

```cpp
Sphere()
```

默认构造函数，使用零初始化 center 为原点，radius 为 0。

**返回：** 无

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
#include <XCEngine/Core/Math/Sphere.h>
#include <XCEngine/Core/Math/Vector3.h>

using namespace XCEngine::Math;

Sphere sphere;
```

Fixed broken references:
- texture-import-settings: Fix 16 files referencing wrong overview filename
- math/rectint: Fix 9 method links (rectint-* → get*, contains, intersects)
- rhi/opengl/device: Fix 8 cross-references (opengl-* → */**)
- resources/mesh: Fix meshsection and vertexattribute links
- rhi/d3d12/sampler: Fix RHISampler reference path
- math/vector3: Fix projectonplane → project-on-plane
- rhi/opengl/command-list: Remove broken ClearFlag enum ref
- rhi/opengl/device: Create 2 new method docs (MakeContextCurrent, GetNativeContext)
- rhi/device: Fix device-info types reference

All 0 broken references remaining.
