<ol type="1">
|

<li><b>不透明句柄</b>: 所有内部对象（网格、曲线、求解器等）通过 <code>typedef</code> 前向声明 隐藏为不透明指针类型，外部代码只能通过 API 函数操作</li>
|
||
<li><b>C 兼容类型</b>: 仅使用 C 原生类型（int, double, const char*）作为参数和返回值</li>
|
||
<li><b>输出通过指针</b>: 复数返回值（如顶点坐标、包围盒）通过输出参数传递，避免结构体 ABI 问题</li>
|
||
<li><b>显式生命周期管理</b>: 每个 create/load 函数都有对应的 free/destroy 函数</li>
