Abstract
AbstractThe paper presents a work that shows an application of digital modeling of human body where CAD has been applied to design and develop a customized shoe last. The customization process has been divided into seven steps which have been mathematically modeled and implemented automatically through a program. The process starts with the generation of point cloud definition of the foot and existing lasts with an Optical Scanner. The point cloud data are registered and processed, and the last closest to the foot in shape and size is selected. B-spline curves and surface patches are fitted on to the point cloud of the last to generate a water-tight geometry of the last. The surface patches are then diagnosed and edited to conform to the geometry of the foot in the desired manner and a modified version of the last is prepared. This version is converted to STL file and rapid prototyping (RP) technology is used to fabricate a sample of the customized shoe last. The file can also be used to generate codes fo...
