Snowflakes from Gravner-Griffeath simulation

cults3d

Martin Krzywinski has crafted an impressive collection of snowflakes generated using the Gravner-Griffeath simulation algorithm, but these snowflakes exist solely as 2D images. You can now transform his 2D snowflakes into STL files with the aid of this javascript webpage. To do so, you will need to provide the snowflake name from Krzywinski's site, and it will then fetch the necessary data from his site and produce an STL file. The sample STLs attached here were all generated using 8 levels. However, beyond that point, the STL files are likely to become too large and unwieldy to be visually appealing. I have also developed a Python script (run gravner_griffeath.py with pypy for speed) that conducts the full Gravner-Griffeath simulation if you wish to alter the parameters. This script generates both STL and SVG files.
