LabeledImage_3

Definition

The concept LabeledImage_3 describes the requirements for the second template parameter of the class 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 ℝ3. A cell of this grid is denoted by voxel. A voxel is an iso-cuboid of size vx(), vy(), and vz().

Types

LabeledImage_3::Type
Type of voxel data. Must be an integral type.


LabeledImage_3::RT
Ring number type.

Operations

int image.xdim () First dimension of the 3D array, i.e., the number of voxels along the x coordinate axis.

int image.ydim () Second dimension of the 3D array.

int image.zdim () Third dimension of the 3D array.

RT image.vx () Size of each voxel along x coordinate axis.

RT image.vy () Size of each voxel along y coordinate axis.

RT image.vz () Size of each voxel along z coordinate axis.

const Type* image.data () Pointer to the first element of the 3D image. The size of the array must be xdim() × ydim() × zdim().

Has Models

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