Lightweight view() Helper

view() is the shortest Python entry point for the lightweight viewer. It is useful in notebooks when you want a PyMOL-style render surface without the full MolecularViewer control panel.

from ase.build import molecule
from aseview import view

atoms = molecule("CH3CONH2")

viewer = view(
    atoms,
    styles="cinematic",
    hide_hs=False,
    center=True,
    bond_threshold=1.25,
    show_bond=True,
    high_performance=True,
    width=500,
    height=420,
)

Trajectory Playback

For a list of ASE Atoms, view() adds a compact play/stop button and frame slider.

viewer = view(
    trajectory,
    styles="bubble",
    fps=24,
    hide_hs=True,
    center=True,
    width=500,
    height=420,
)

Save the Same Viewer

view() returns the underlying LiteViewer, so the same object can be saved as standalone HTML.

viewer.save_html("lite_view.html")

Common Options
