Crystal Forms

This app lets the user create crystal shapes from a given list of {hkl} forms and their central distance values. A distance slider (range 0.1-3) can be used for real-time adjustments (for values >3 use text input). The generated crystal shapes are freely rotatable. Also shown is a static stereographic projection plot.

Please note that the true unit cell constants 'abc' of minerals etc. do not need to be used. When creating crystal shapes, it is sufficient when they represent the correct axis ratios. This app only has a GUI real estate for 6 forms, whereas for lower symmetry crystals one would often need more.


Features:
- Select a crystal class / point group
- Enter the editable unit cell dimensions
- Enter '{ h k l }' & 'Distance' values and check their checkbox
- When a closed form can be created, the 3D shape is displayed
- Not all inputs can create viable polyhedra
- Several rendering modes (solid, translucent, drawing)
- Offline app (no Internet required)
