【问题描述】：
我在使用 swig 包装 c 函数以在 python 代码中使用时遇到属性错误。我在 chap 旁边还有其他功能可以正常工作，但有些奇怪的原因是这个不能工作：/
我正在尝试使用 CGAL 来确定所有粒子的凸包（章节）。下面是 chap 函数和回溯：
std::vector<Vec2d> World::chap() const
{
std::vector<Point_2> ch;
std::vector<Point_2> points;
std::vector<Vec2d> result;
for(size_t i = 0, sz = particles.size(); i < sz; ++i)
{
points.push_back(Point_2(particles[i]->position.x, particles[i]->position.y));
}
CGAL::convex_hull_2(points.begin(), points.end(), std::back_inserter(ch));
for(size_t i = 0, sz = ch.size(); i < sz; ++i)
{
result.push_back(Vec2d(ch[i].x(), ch[i].y()));
}
return result;
}
Traceback (most recent call last):
