TEX Technology

Based on topology, TEX sorts into 4 groups, the tetrahedra resulting from a Delaunay tetrahedralization of an input mesh representing the surface of the object to be meshed. The groups are labeled 0-D, 1-D, 2-D and 3-D.

3-D tetrahedra connect separate stacks of 2-D tetrahedra to form a network of prisms aligned with the edges of the object. This network of prisms encloses swaths of extrudable volumes within the object. Extrudable volumes are meshed as extruded quad meshes while the remaining prisms and 3D-tetra are algebraically meshed to create an all-hexahedral mesh of the entire object.

Computationally, TEX relies on fast local mesh manipulations which lend themselves to parallelization.
