StuffingLattice

Where a field sits in a larger lattice, for a chunked export (construct-tet-export Phase 4).

In the namespace construct::mesh. Declared in src/libs/libconstruct/construct/mesh/IsosurfaceStuffing.hpp.

Detailed description

A chunk stuffs its own cells, and samples one more lattice point on every side that has a neighbor chunk: the warp of a point on the seam reads every cell around it, and half of them are the neighbor's. Both chunks then decide every seam point the same way, and the tets of the two chunks meet face to face.

The lattice keys, the parity of the 5-tet split and the positions come from the global index, so a seam point has the same key and the same float bits in both chunks. The default places the field as the whole lattice.
