示例1: chained_path
Polylines PolylineCollection::chained_path(const Polylines &src, bool no_reverse)
{
return (src.empty() || src.front().points.empty()) ?
Polylines() :
_chained_path_from(src, src.front().first_point(), no_reverse
#if SLIC3R_CPPVER >= 11
, false
#endif
);
}示例2: main
int main()
{
// Domain (Warning: Sphere_3 constructor uses squared radius !)
Mesh_domain domain(sphere_function,
K::Sphere_3(Point(1, 0, 0), 6.));
// Mesh criteria
Mesh_criteria criteria(edge_size = 0.15,
facet_angle = 25, facet_size = 0.15,
cell_radius_edge_ratio = 2, cell_size = 0.15);
// Create edge that we want to preserve
Polylines polylines (1);
Polyline_3& polyline = polylines.front();
for(int i = 0; i < 360; ++i)
{
Point p (1, std::cos(i*CGAL_PI/180), std::sin(i*CGAL_PI/180));
polyline.push_back(p);
}
polyline.push_back(polyline.front()); // close the line
// Insert edge in domain
domain.add_features(polylines.begin(), polylines.end());
// Mesh generation without feature preservation
C3t3 c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria,

// Output
