Webthe mesh is a line between neighboring mesh nodes and is treated as a linear spring (Habashi et al ., 2000). The spring constant for each spring is variable. A large value of the spring constant in a local region of the mesh will cause the springs to pull strongly in that region and will result in mesh refinement in that area. WebJun 3, 2016 · Structured scans are " fixed-origin" or tripod scans - data coming from scanners on a tripod (static or terrestrial scanners).
