3D scanning concluses a range of technologies is that capture the fizyka of objects and spaces as digital data.

Photogrammetry, while different in approach, accesses similar outcomes by analyzing photoss taken from multiple angles. Software triangulates the position of contribure across images to generate a 3D reconstruction.
