Presets

How to Apply a Preset

Presets can be found at the top of the sidebar menu. Just create a snowflake, select the preset and grow it!

Gallery

These are renderings of all available presets. Currently, all presets are derived from the figures in the original publication [GG08]. The number of simulation steps required to reproduce the presets is given in the captions.

For presets 15bl, 15bm, and 15br, you should manually adapt some parameters as described in the caption. These parameter changes are identical to those presented in the original paper and allow simulating changing air conditions during the fall of a snowflake.

Note

The look of the presets depends a lot on the number of simulation steps. Here, we only show one picture per preset. However, they can also look quite differently if you let them grow shorter or longer.

Creating Your own Presets

You can also easily create your own presets. Just open the snowflake sidebar menu, create or select a snowflake, enter the desired parameter values, click on the presets button and then on New Preset.
