- Subject: [cgal-discuss] Smooth external surface when meshing 3D images
- Date: Fri, 14 Aug 2015 15:49:13 +0200
Hi, I am using CGAL to mesh 3D medical images described with the CGAL::Labeled_image_mesh_domain_3 class. These images have labels assigned to different regions, much as in the example: http://doc.cgal.org/latest/Mesh_3/index.html#Mesh_3DomainsFromSegmented3DImages However, while the internal boundary between the different labels in the resulting mesh are smooth, on the external surface there are small 'gaps' in the mesh at the join, which I would like to avoid (as in the image below). Do you know of some method by which I can enforce a smooth external surface to the mesh? I had a look at the feature preservation (with a view to enforce preservation of the external 2D surface), but it seems that only 0D and 1D features may be preserved. Best wishes, Andrew Crozier |
