3D Scanning
3D scanning is a technology that captures the shape and appearance of physical objects to create digital 3D models. It uses various methods like laser triangulation, structured light, or photogrammetry to collect surface data points, which are then processed into mesh or CAD models. This enables accurate digital replication of real-world objects for applications in manufacturing, healthcare, and entertainment.
Developers should learn 3D scanning when working in fields like reverse engineering, quality control, or digital archiving, where precise physical-to-digital conversion is needed. It's essential for creating assets in VR/AR, 3D printing, and cultural heritage preservation, allowing integration of real objects into digital workflows without manual modeling.
