x3dase

Python module for drawing and rendering atoms and molecules objects using X3DOM. X3dase can be used as a viewer for the molecule structure in the Jupyter notebook.

Functions:

• Support all file-formats using by ASE, including cif, xyz, cube, pdb, json, VASP-out and so on.
• Ball & stick
• Space filling
• Polyhedral
• Isosurface
• Show element and index
• Measure distance and angle
• Animation
