Abstract

The solution according to the invention is an automatic method for preparing statue-like copies of bodies during which a three-dimensional virtual copy is created based on digitally recorded data of image points surveyed from multiple directions using a new image editing algorithm, a tactile copy is then created based on the original data file describing the copy. Steps of the procedure: scanning/data survey (1); data retrieval (2); creation of rough mesh (3); updating first cycle (4); densifying second cycle (5); refining third cycle (6); reduction/magnification (7); data saving to file / recording (8); printing / plotting (9). The procedure can be regarded as the spatial equivalent of photography.
