Understanding 3D Scanning Technology

3D scanning is a process that collects data about te shape, dimensions, and appearance of real-term objects or environments. Specializad devices emices some form of energy (like laser light or structured light) and metriuts the reflections to generate a dense set of points in three- dimensional space - known as a point cloud. This point cloud is then processed and converted into a mesh or solid model thatt cae imposletd intal o, simulation, and analysiars.
