Class GeometryIdentifier

Class Documentation

class Acts::GeometryIdentifier

Identifier for geometry nodes within the geometry hierarchy.

An identifier can be split into the following components. They define a hierarchy of objects starting from the high-level volumes:

  • Volume

  • Boundary surfaces (for a volume)

  • Layers (confined within a volume)

  • Approach surfaces (for a layer)

  • Sensitive surfaces (confined to a layer, also called modules)

Public Types
