Dear CGAL developers,
In the past week or so, I've become interested in the new capacity of 3.8 to offer boundary-faithful and controlled-resolution tetrahedralization.
Returning to the example in
examples/Mesh_3/mesh_two_implicit_spheres_with_balls.cpp,
playing with the mesh size a little bit,
Mesh_criteria criteria(edge_size = 0.5,
facet_angle = 25, facet_size = 0.5,
cell_radius_edge_ratio = 2, cell_size = 0.5);
c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria,
odt(time_limit=30),
perturb(sliver_bound=10, time_limit=30),
exude(time_limit=30, sliver_bound=15));
and visualizing the interior with Paraview (by producing a vtk file),
vtkSmartPointer<vtkUnstructuredGrid>
outputUnstructuredGrid = vtkSmartPointer<vtkUnstructuredGrid>::New();
CGAL::output_c3t3_to_vtk_unstructured_grid(c3t3, outputUnstructuredGrid);
outputUnstructuredGrid->Squeeze();
vtkSmartPointer<vtkUnstructuredGridWriter> writer =
vtkSmartPointer<vtkUnstructuredGridWriter>::New();
writer->SetInput(outputUnstructuredGrid);
writer->SetFileName("out.vtk");
writer->Write();
I'm finding nonetheless that some slivers remain in the peanut... See the enclosed visualization. I'd be happy to help track down the problem. Is this a parameter of odt(), perturb() or exude() that I am not using properly?
Best wishes,
Michel
