# Vector3::operator==

```cpp
bool operator==(const Vector3& other) const
```

判断两个向量是否相等。使用 EPSILON 进行浮点数比较。

**参数：**
- `other` - 要比较的向量

**返回：** `bool` - 如果两个向量相等返回 true，否则返回 false

**线程安全：** ✅

**复杂度：** O(1)

**示例：**

```cpp
Vector3 a(1.0f, 2.0f, 3.0f);
Vector3 b(1.0f, 2.0f, 3.0f);
Vector3 c(1.0f, 2.0f, 3.00001f);

bool equal1 = (a == b);  // true
bool equal2 = (a == c);  // true（因为差异在 EPSILON 内）
```
