3Dskenen

3Dskenen is the process of producing digital three‑dimensional models of real-world objects or environments by capturing their shape, color, and texture with specialized scanning technologies. It combines geometric data with surface appearance to create representations that can be visualized, analyzed, archived, or used in manufacturing and design workflows. While the term is commonly associated with Danish-speaking contexts, it is understood in international discussions as a form of 3D scanning.

Techniques used in 3Dskenen include structured light, laser scanning, and photogrammetry. Structured light and laser scanners project signals onto a surface and measure distortions to determine geometry, while photogrammetry reconstructs 3D models from many photographs. The data capture stage often yields point clouds or sparse scans that are processed into dense meshes, sometimes with texture. Output formats such as STL, OBJ, PLY, and USD are commonly used to export the results for further editing in CAD, animation, or visualization software.

Applications span many industries. In manufacturing and engineering, 3Dskenen supports reverse engineering and quality control. In cultural heritage and archaeology, it enables preservation and digital documentation of artifacts and sites. In architecture, film, and gaming, it provides realistic proxies for objects and environments. Medical fields use 3D scans for prosthetics and planning. Limitations include difficulties with shiny or translucent surfaces, occlusions, and large-scale data handling, as well as varying accuracy depending on the method and equipment.

Advances continue in scanner resolution, speed, and integrated color capture, broadening accessibility for professionals and hobbyists alike.
