2. Packard Snowflakes and their Growth Simulation Method
Two models for snowflake growth:
Version of DLA that uses updated mass values instead of random walks
Cellular automata based on a hexagonal lattice seed state
Starts from a single occupied cell and creates a web that serves as boundary conditions for water solidification
Properties of Growth (Cellular Automata):
Different types of snowflakes (hex1, hex135, hex1456, etc.)
Hex1: A site with exactly one neighbor always becomes filled at the next time step, but a site with more than one neighbor does not
Hex1456: A site with exactly one, four, five, or six neighbors always becomes filled at the next time step, but a site with any other number of neighbors does not
What about the hexagonal lattice seed state?
Working with Cartesian coordinate plane (equivalent to a square lattice seed state), but can approximate the shape of the lattice by ignoring the top right and bottom left cells
