5 Medial Axis Projection algorithm can be used for meshing faces with
6 sinuous borders and having channel-like shape, for which is it
7 difficult to define 1D hypotheses so that generated quadrangles to be

12 The algorithm assures good shape of quadrangles by constructing Medial
13 Axis between sinuous borders of the face and using it to
14 discretize the borders.

18 The Medial Axis is used in two ways:
20 <li>If there is a sub-mesh on either sinuous border, then the nodes of
21 this border are mapped to the opposite border via the Medial
23 <li> If there is no sub-meshes on the sinuous borders, then a part of
24 the Medial Axis that can be mapped to both borders is discretized
25 using a hypothesis assigned to the face or its ancestor shapes,
26 and the division points are mapped from the Medial Axis to the both
