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().
| LabeledImage_3::Type | |
|
Type of voxel data. Must be an
integral type.
| |
| LabeledImage_3::RT | |
|
Ring number type.
| |
| 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(). |
