Surface proximity

When showing the molecular surface of a subset of atoms (not the entire molecule), then the surface_proximity setting controls whether triangles are shown which are between an included and an excluded atom.

Values

• surface_proximity=on: (default) Show all triangles which have at least one vertex belonging to the atom selection. In this case colors from hidden atoms can leak into the open surface edge.
• surface_proximity=off: Show only triangles where all three vertices belong to the atom selection.

Example

This example demonstrates the color "leaking" from atoms which don't belong to the surface selection.
