Creates a geometric model corresponding to the given conforming mesh which must be either a 2D or 2D5 mesh, ie a surface. The resulting model will have either have type WLZ_GMMOD_3D (from 2D5) or WLZ_GMMOD_2D (from 2D).
mObj | Given conforming mesh. |
disp | Scale factor for the displacements, 0.0 implies no displacements, 1.0 implies full displacement. |

WlzErrorNum WlzCMeshLaplacianSmooth | ( | WlzCMeshP | mesh, |
int | itr, | ||

Applies a Laplacian smoothing to the 2D mesh in which nodes are iteratively moved to the centroid of their imediate neighbours. If a node is on a boundary of the mesh then it is moved on the boundary, ie to the centroid of it's neighboring boundary nodes. Before calling this function all nodes must have had the boundary node flag bit set or cleared appropriately. This function will shrink meshes when the boundary parameter is set.
Each node at position \form#166 is moved to \form#167:
\[ p'_i = (1 - \alpha)p_i + \frac{\alpha}{n}\sum_{j}^{n}{p_{ij}} \]

Given a conforming mesh with attached values; this function normalises the values to the given range in place. If the zero value is not mapped to a given value explicitly then the the output values will be given using:
\[ V = \frac{U - L}{u - l} (v - l) + L \]
otherwise with the zero value explicitly mapped the values will be
\[ \begin{array}{l} f = \min{\frac{U - V_0}{u}, \frac{L - V_0}{l}} \\ V = f v + V_0 \end{array} \]
Here \(U\) and \(L\) are the required maximum and minimum values on return, \(u\) and \(l\) are the given mesh maximum and minimum values, \(v\) is a given value and \(V\) is a returned value. \(V_0\) is the returned value corresponding to the given value of zero.

Constructs a 3D mesh from a balanced 3D linear binary tree domain.
For tesselation of a 3D LBT node, each node is condidered to be a cube. This can conviniently be represented by it's net and using this representation there are 10 possible node-neighbour relationships when the rotational degeneracy is ignored:
Y ^ f1 | v4 | v5 |/ | / *---------------@ |\ : :\ | \ : : \ f2 | \ : : \ / | \ f5 : \/ | \ : .\ v0 | \ v7 : . \ v6 \| \ / : \ / @...f4..@-------*-------*---->X \ | / . | \ | v1 . | \ | . | \ | . f3 . | \ | . . | \ | v3 . . | v2 \|/ . .|/ @---------------@ \ \ \ \ Z % f0
Faces are defined to have the following orientations, when viewed from outside the cube:
+z +y +y +y +y +x 3-----2 5-----4 6-----5 7-----6 4-----7 5-----6 | | | | | | | | | | | | -x| 0 |+x +x| 1 |-x +z| 2 |-z -x| 3 |+x -z| 4 |+z -z| 5 |+z | -y| | -z| | +x| | +z| | -x| | +y| 0-----1 1-----0 2-----1 3-----2 0-----3 4-----7 -z -y -y -y -y -x
The neighbouring nodes to each of these faces can be found using 3 orthogonal vectors (looking from outside the cube):
^ o2 | | +--|--+ o3 = -o1 | | o4 = -o2 o3 <--- ----> o1 | \| +--|--\ | % o0 o4 | V

By placing a mesh node at the centre of the cube, each face can be tesselated with tetrahedra almost independently of the other faces. This gives the following possible teselations, in which each facet on the cubes surface forms a tetrahedron with the node at the cubes centre. Here the cube faces which share an edge obviously influence the tesselation of a face and so reduce the number of classes to 6:
+---+ +-+-+ +-+-+ +-+-+ 0=(0) |\ /| 1=(1) |\|/| 2=(2) |\|/| 3=(3) |\|/| | X | +-X-+ +-X-+ +-X-+ |/ \| |/|\| |/|\| |/|\| +---+ +-+-+ +-+-+ +-+-+ |\ /| |\|/| |\|/| |\|/| | X | | X | +-X-+ | X | |/ \| |/ \| |/|\| |/|\| +---+---+---+ +---+---+---+ +-+-+---+-+-+ +---+-+-+---+ |\ /|\ /|\ /| |\ /|\ /|\ /| |\|/|\|/|\|/| |\ /|\|/|\ /| | X | X | X | +-X | X | X-+ +-X | X | X-+ +-X-+-X-+-X-+ |/ \|/ \|/ \| |/ \|/ \|/ \| |/ \|/ \|/ \| |/ \|/|\|/ \| +---+---+---+ +---+---+---+ +---+---+---+ +---+-+-+---+ |\ /| |\ /| |\ /| |\|/| | X | | X | | X | | X | |/ \| |/|\| |/|\| |/|\| +---+ +-+-+ +-+-+ +-+-+ +-+-+ +-+-+ +-+-+ +-+-+ 4=(4) |\|/| 5=(5) |\|/| 6=(6) |\|/| 7=(7,8,9) |\|/| +-X-+ +-X-+ +-X-+ +-X-+ |/|\| |/|\| |/|\| |/|\| +-+-+ +-+-+ +-+-+ +-+-+ |\|/| |\|/| |\|/| |\|/| +-X-+ +-X-+ +-X-+ +-X-+ |/|\| |/|\| |/|\| |/|\| +-+-+-+-+-+-+ +-+-+-+-+-+-+ +---+-+-+---+ +-+-+-+-+-+-+ |\|/|\|/|\|/| |\|/|\|/|\|/| |\ /|\|/|\ /| |\|/|\|/|\|/| +-X-+-X-+-X-+ +-X | X-+-X-+ +-X-+-X-+-X-+ +-X-+-X-+-X-+ |/ \|/|\|/ \| |/ \|/ \|/|\| |/|\|/ \|/|\| |/|\|/|\|/|\| +---+-+-+---+ +---+---+-+-+ +-+-+---+-+-+ +-+-+-+-+-+-+ |\|/| |\ /| |\ /| |\|/| | X | | X-+ +-X-+ +-X-+ |/|\| |/|\| |/|\| |/|\| +-+-+ +-+-+ +-+-+ +-+-+
These possible cube face tesselations lead to 6 possible cube face tesselations which define struct::_WlzLBTNodeClass2D.
