CGAL 4.7  3D Mesh Generation

#include <CGAL/Labeled_image_mesh_domain_3.h>
The class Labeled_image_mesh_domain_3
implements a domain described by a 3D labeled image.
A 3D labeled image is a grid of voxels, where each voxel is associated with an index (a subdomain index) characterizing the subdomain in which the voxel lies. This class is a model of the concept MeshDomain_3
. The domain to be discretized is the union of voxels that have an nondefault index (different from the default constructed value of the type Image::Type
).
This class includes a member function that provides, by interpolation, the subdomain index of any query point. An intersection between a segment and bounding surfaces is detected when both segment endpoints are associated with different values of subdomain indices. The intersection is then constructed by bisection. The bisection stops when the query segment is shorter than a given error bound e
. This error bound is given by e=d
\( \times\)bound
where d
is the length of the diagonal of the bounding box (in world coordinates) and bound
is the argument passed to the constructor of Labeled_image_mesh_domain_3
.
Image  is the type of the input image. This parameter must be a model of the concept LabeledImage_3 . 
BGT  is a geometric traits class which provides the basic operations to implement intersection tests and intersection computations through a bisection method. This parameter must be instantiated with a model of the concept BisectionGeometricTraits_3 .
