Athene
(also spelled Athena), an ancient Greek God, is the patron of wisdom,
military victory, and women's crafts. She is also known as Tritogeneia
and Minerva (Roman) and is also called Pallas Athene. Her attributes
in iconography include the aegis (a fringed cloak, sometimes decorated
with a Gorgon's head), the helmet, and the spear.
The input surface mesh, 14925 nodes, 29708 triangles.
I got the source data freely from Inria
(use "athene" as the search text). However, it is not in a state that
can be meshed because the surface mesh was not closed. The one in the
above model was patched by me with several additional triangles for
the clossness.
The constrained Delaunay tetrahedralization, 25689 nodes, 84457
tetrahedra, and 51236 boundary faces.
The constrained Delaunay tetrahedralization, same as above, a closed view.
