7 This algorithm applies to the meshing of a hollow 3D shape,
8 i.e. such shape should be composed of two meshed shells: an outer
9 shell and an internal shell without intersection with the outer
10 shell. One of the shells should be a :ref:`2D Projection <projection_2D>` of the other
11 shell. The meshes of the shells can consist both of triangles and
14 The Radial Prism algorithm would fill the space between the two shells

23 This algorithm also needs the information concerning the number and
24 distribution of mesh layers between the inner and the outer shapes.
25 This information can be defined using either of two hypotheses:
27 .. image:: ../images/number_of_layers.png
31 *"Number of layers"* hypothesis
33 .. image:: ../images/distribution_of_layers.png
37 *"Distribution of layers"* hypothesis
39 *Distribution of layers* hypothesis allows using most of
40 :ref:`1D Hypotheses <a1d_meshing_hypo_page>` to define
41 the distribution of mesh layers.
