# VDE-015: StlTrianglef 中 Vector3F / Point3F 拼写错误

## 问题描述

`io_stl.h` 中 `StlTrianglef` 结构体使用了 `Vector3F` 和 `Point3F`，但 `math_types.h` 中定义的类型是 `Vector3f` 和 `Point3f`（小写 `f`）：

```cpp
// io_stl.h:126-128 — 当前（错误）
struct StlTrianglef {
    Vector3F normal;  // 应为 Vector3f
    Point3F  v0, v1, v2;  // 应为 Point3f
};
```

## 编译错误

```
error: 'Vector3F' does not name a type
error: 'Point3F' does not name a type
error: 'Vector3F' is not a member of 'vde::foundation'
error: 'Point3F' is not a member of 'vde::foundation'
```

## 建议修复

改为正确的大小写：

```cpp
struct StlTrianglef {
    Vector3f normal;
    Point3f  v0, v1, v2;
};
```
