搜索查询返回此错误.我有一种感觉,因为当我试图对另一个对象进行ORM时,in子句在下属对象上是巨大的.
显然,在子句中不应该一次构建1个参数.谢谢ibatis.

我的Delaunay三角测量在1000个均匀随机点上的结果看起来并不正确(见图).有些点似乎属于异常高数量的三角形......有什么想法吗?

细节:CGAL 3.4,Windows XP
这是我使用的类型:
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef CGAL::Triangulation_2<K> Triangulation;
typedef Triangulation::Point Point;

显示如下:
delaunay_c::Triangulation::Edge_iterator eit = T.edges_begin();
delaunay_c::Triangulation::Edge_iterator end = T.edges_end();
for(;eit != end; ++eit)
{
delaunay_c::Triangulation::Segment s = T.segment(eit);
line.m_a = delaunay_c::convert(s.source());
line.m_b = delaunay_c::convert(s.target());
line.draw();

函数转换只是从CGAL Point转换为另一种点格式
编辑:按照选择的答案,我只是将三角测量改为delaunay_triangulation:
