A digital representation of a physical object, system, or environment created through 3D modelling, photogrammetry, or LiDAR scanning, serving as a static or dynamic copy for visualisation, simulation, analysis, and testing without the real-time bidirectional data connectivity that distinguishes a full digital twin. Virtual replicas are typically point-in-time snapshots; they support heritage preservation, product safety testing, urban planning, and manufacturing visualisation workflows.

Overview
- Virtual replicas are digital copies of physical objects or environments used for visualization and simulation. Unlike digital twins that maintain real-time data connectivity, virtual replicas are typically static representations or models with limited update capabilities. Creation often begins with 3D scans using LiDAR or structured-light scanning to capture precise geometry. The global digital twin market is projected to reach $73.5 billion by 2027 with 60% annual growth.
