Meshing essentially means you are connecting the dots of the point cloud to produce a complete model. Once the scanner has created the point cloud, it then meshes it to turn it into a 3D model made up of surfaces. The process of extrapolating the shape of a subject from points is known as reconstruction. Altogether, these 3D points form a point cloud, which appear like in the image below. All 3D scanners use a sensor, which may be a physical probe, laser or light, to measure the distance between a camera and an object.ģD scanners are able to identify 3D points, calculated from photos and depth measurement using triangulation, with each point appearing on the screen individually. While there are a variety of different 3D scanning techniques, they all rely on the same principles.
