Editing Surface carve selection

[[File:surface_carve_selection.gif||thumb|right|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 [[show|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 Atom Selections|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
