Detailed Description

Retrieve the surface ID between two volume instances.

Given (old, new) physical volumes P0, P1 corresponding to logical volumes L0, L1

• Ordered (P0, P1) interface surface
• Boundary surface of L0
• Boundary surface of L1

This behavior differs from Geant4's order of precedence, which considers if there's a mother-daughter relation between L0 and L1 when both have a boundary surface:

• Ordered (P0, P1) interface surface
• Boundary surface of L1 if it's the daughter of L0
• Boundary surface of L0
• Boundary surface of L1

When multiple layers are implemented, this selector will be responsible for determining the ordering of the layers between the volumes, including both interface and boundary surfaces.

CELER_FUNCTION SurfaceId celeritas::optical::VolumeSurfaceSelector::operator() ( VolumeId  post_volume, VolumeInstanceId  post_volume_inst  ) const

inline

Select surface based on post-volume IDs.

Returns an invalid SurfaceId if no surface data exists for the volumes.
