LabeledImage_3 Concept Reference

Definition

The concept LabeledImage_3 describes the requirements for the second template parameter of the class CGAL::Labeled_image_mesh_domain_3<Image,BGT> which represents mesh domains defined by 3D labeled images. A 3D labeled image is a 3D array of elements of an integral type Type. Type can be bool, char, short, int, or long (signed or not). Such an array is associated to a 3D axis-aligned regular grid, in \( \mathbb{R}^3\). A cell of this grid is denoted by voxel. A voxel is an iso-cuboid of size vx(), vy(), and vz().

Has Models:

CGAL::Image_3<Kernel, T>, for any CGAL kernel K and any integral type T
