Animation with a moving pseudoatom as the surface_carve_selection

With the surface_carve_selection and surface_carve_cutoff settings, the visibility of a molecular surface can be limited to the proximity of an atom selection.

Unlike when showing surface representation only for a subset of atoms, the visibility is controlled on the vertex (surface point) level, not the atom level.

The value of surface_carve_selection must be a named selection (created with select), it cannot be a selection expression (e.g. "chain A" won't work).

Example

Visibility control on the vertex level. Hide surface points which are more than 5 Angstrom away from carvesele:

fetch 1rx1, async=0
as cartoon
select carvesele, organic
set surface_carve_selection, carvesele
set surface_carve_cutoff, 5
show surface
show sticks, carvesele

Compare to visibility control on the atom level. Hide surface for atoms which are more than 5 Angstrom away from carvesele.

fetch 1rx1, async=0
as cartoon
select carvesele, organic
show surface, all within 5 of carvesele
show sticks, carvesele
