3D modelers create accurate historical artifact representations by integrating 3D scanning, manual measurements, and reference materials, ensuring the digital model mirrors physical details through multi-source data merging.
They use tools like laser scanners or photogrammetry (capturing 3D data via photos) to record surface textures and shapes. Manual verification with calipers or historical records cross-checks precise dimensions. For fragile artifacts, non-contact scanning methods preserve the original while maintaining accuracy.
