Detailed Description

This module provides a Qt widget that presents the detector geometry as a hierarchical tree. It enables users to toggle visibility and adjust visual attributes (color, opacity, representation) for individual volumes.

The group is intentionally named with a module-specific prefix to avoid collisions across tag-file modules.
