WebAug 11, 2014 · 1. lattice points are mathematical objects. In fact, a lattice is an infinite array of points in space where each point has identical surroundings to all others. A lattice is thus a purely abstract mathematical object. In 3 dimensions there exist the 14 Bravais lattices filling all space. WebFeb 17, 2024 · In 2-D, there are 5 possible lattices namely, square, rectangle, hexagonal, parallelogram and rhombic. In 3-D, there are 14 possible lattices, and these lattices are called Bravais lattices (after the French mathematician who first described them) like cubic primitive, hexagonal primitve, etc.
WebSep 5, 2016 · In three dimensions, there are exactly 14 types of Bravais lattices. A primitive lattice is one such example. A primitive lattice is generated by repeating a primitive unit cell, which contains a single lattice point. An example of a primitve unit cell in three dimension would be a cube with lattice points only at the vertices.
