Direzione di ricerca

Look for the dimple anode viewer code, likely in a file related to dimple or viewer. The provided helper function shows how to focus on an isosurface. Find where the viewer currently focuses on the nearest atom and modify it to use the isosurface focus method. Test by running the viewer with anomalous density blobs to ensure the view centers on the blob.

Descrizione

The dimpe anode viewer focusses on the nearest atom to the blob. In cases of unmodelled anomalous density, the blob can be outside of the focussed view as it picks the nearest atom.

Encountered a similar problem when making the metal_iid viewer and solved it with this helper function, which focusses on the isosurface itself rather than the nearest atom:
