AlphaPlugins IcePattern can create different kinds of patterns.
One group of possible ice pattern designs is Geometric patterns. You can select a Geometric pattern in the listbox Effect kinds on AlphaPlugins IcePattern dialog window. Different kinds of geometric patterns define how frozen shapes will grow up.
You can adjust many parameters to change the appearance of the selected geometry type.
I recommend you set Render mode as Rough while you are adjusting geometry parameters for increased drawing speed.
