Creating a Procedural Snowflake in Houdini

The technique stems from Cliff Reiter’s brilliant paper called “A local cellular model for snow crystal growth”. Don’t fret – We’ll do our best and explain what’s actually going on here. In essence, it is a rather straightforward yet extremely efficient (and quite clever) cellular automaton we’re building. Hope we didn’t scare you with that previous sentence. Relax – all we’re doing is simulate small particles of water that are allowed to move in a hex-grid. Enough talk, let’s build it!
