Radial Prism

This algorithm applies to the meshing of a hollow 3D shape, i.e. such shape should be composed of two meshed shells: an outer shell and an internal shell without intersection with the outer shell. One of the shells should be a 2D Projection of the other shell. The meshes of the shells can consist both of triangles and quadrangles.

The Radial Prism algorithm would fill the space between the two shells with prisms.

This algorithm also needs the information concerning the number and distribution of mesh layers between the inner and the outer shapes. This information can be defined using either of two hypotheses:


“Number of layers” hypothesis


“Distribution of layers” hypothesis

Distribution of layers hypothesis allows using most of 1D Hypotheses to define the distribution of mesh layers.
