2D Tessellations: Patterns That Tile the Plane

What Are Tessellations?

A tessellation is a pattern of shapes covering a plane without gaps or overlaps. These patterns can be created using regular polygons like squares, triangles, and hexagons, but also through more complex designs that mimic natural forms or artistic creations.

Tessellations are not just abstract mathematical concepts; they have practical applications in fields such as architecture, art, and crystallography.

Lattice Vector Math

Lattice vectors define the repeating pattern of a tessellation. In 2D, these can be represented by two non-parallel vectors that span the plane. By adding multiples of these vectors, you can generate all points in the tessellation.

For example, in a square lattice, one vector might point right and the other upwards; in a hexagonal lattice, vectors would point to adjacent vertices.

Escher-Style Transformations

M.C. Escher's artwork often featured tessellating patterns that transformed from one shape to another seamlessly. In 2D tessellation simulations, you can achieve similar effects by dragging control points on a tile edge, which triggers mirror reflections or translations to maintain the tessellation.

These transformations are governed by symmetry groups, such as rotations and reflections, ensuring the pattern remains consistent across the plane.

Applications of Tessellations

Tessellations have numerous applications. In architecture, they can inspire unique building designs that optimize space and aesthetics. In crystallography, understanding tessellation patterns helps in identifying different types of crystals.

Artists use tessellations to create intricate and seamless designs, often seen in M.C. Escher's work.
